I really like the product. I find it very good. The price is fair, if it were cheaper it would be better, but it's fine. I really like the product. I find it very good. The price is fair, if it were cheaper it would be better, but it's fine. AssemblyAI speech to text API is really easy to use; I’m not a tech profile and I use it both with automation platforms (such as Zapier) and custom code. It is cheap, for some use cases it costs almost nothing! (For example: understanding voicemail). And, with the latest model, it is very accurate. **What do you dislike about AssemblyAI - Speech to Text API?** It would be better if the cost were even lower, but it's fine as it is. It will be perfect if in Zapier I can choose EU residency. **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** AssemblyAI helps me automate the transcription of audio content, saving a lot of time and increasing work efficiency. It is perfect for analyzing large amounts of audio data that would be impossible to manage manually. ### 25. Easy to Implement and Cost Competitive **Rating:** 4.0/5.0 stars **Reviewed by:** Fabio V. **Reviewed Date:** February 15, 2026 **What do you like best about AssemblyAI - Speech to Text API?** I like the ease of implementation and the cost of AssemblyAI - Speech to Text API. The initial setup was very easy. **What do you dislike about AssemblyAI - Speech to Text API?** The cost is not very clear and the use of the account is little explored. Sometimes the cost per transcribed hour does not match what is seen on the pricing pages. There is a huge difference in the usage details, for example with OpenAI's APIs. **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** I use it to transcribe meetings, facilitating the creation of summaries. ### 26. Solid Speech-to-Text API but Needs Speed Improvements **Rating:** 3.0/5.0 stars **Reviewed by:** sai c. **Reviewed Date:** November 08, 2025 **What do you like best about AssemblyAI - Speech to Text API?** I find AssemblyAI - Speech to Text API to be highly effective for transcription tasks. Its functionality allows me to seamlessly convert speech into text, particularly highlighting the straightforward nature of this task, which the service handles adeptly. I also appreciate its real-time streaming capabilities, which enhance the efficiency and practicality of the tool for immediate transcription needs. The initial setup of AssemblyAI - Speech to Text API is easy, making it accessible and convenient to integrate into my workflow without any complications. **What do you dislike about AssemblyAI - Speech to Text API?** I experience issues with the speed of AssemblyAI - Speech to Text API, which seems heavy and potentially slows down processes. **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** I use AssemblyAI - Speech to Text API for simple, straightforward transcription, turning speech into text efficiently. **Official Response from Lee Vaughn:** > Hi Sai!

Please reach out to our support team at support@assemblyai.com with more details on the issue you are seeing, and we would be happy to help! ### 27. Excellent support. Low cost. **Rating:** 5.0/5.0 stars **Reviewed by:** Vladyslav H. | CMO, Small-Business (50 or fewer emp.) **Reviewed Date:** July 07, 2025 **What do you like best about AssemblyAI - Speech to Text API?** Excellent documentation and responsive support that will help you resolve any issues with using the API. Multiple language support and automatic detection. The ability to upload files directly to their server, which makes it faster than saving them to third-party services. You pay for usage instead of a subscription, which is very nice. **What do you dislike about AssemblyAI - Speech to Text API?** During my time using the service, I haven't found much that I dislike. The main my issue is that I would like to see support for video files from services such as YouTube directly via a link. Currently, I have to use third-party services to download and process videos from YouTube before sending them to AssamblyAI. **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** I am a mobile and web application developer. My applications are based on converting video or audio files into text. Therefore, AssamblyAI fully covers all the functionality of my applications. **Official Response from Devon Malloy:** > Thank you for this wonderful review, it's great to hear that AssemblyAI is powering your mobile and web applications successfully! Your feedback about direct YouTube URL support is super valuable—we've passed your note on to our product team to explore. If you'd like to stay updated on new features or have additional suggestions, please don't hesitate to reach out to our support team at [support.assemblyai.com]. ### 28. Affordable and Easy-to-Integrate Transcription Service **Rating:** 5.0/5.0 stars **Reviewed by:** Павел . | Xamarin Developer, Small-Business (50 or fewer emp.) **Reviewed Date:** June 23, 2025 **What do you like best about AssemblyAI - Speech to Text API?** I'm impressed with AssemblyAI's transcription service due to its reasonable pricing. For transcribing 243 hours of audio, I paid only $68. In comparison, Google's Chirp_2 model cost $47 for just 35 hours, which would have totaled $326 for the same 243 hours. Additional benefits include the ability to separate text by different speakers (English only) and automatic language detection. The API is straightforward to use and was easy to integrate into both Flutter and .NET Core Web applications. Overall, I'm satisfied with the service and plan to continue using it. **What do you dislike about AssemblyAI - Speech to Text API?** There are some aspects I'd like to see improved. The API response contains too many unnecessary fields that I don't need, which increases loading times. I would also appreciate faster speech-to-text processing speeds and an increase in the maximum duration limit beyond the current 10-hour restriction. Additionally, the slam-1 model only works with English text, and I would like to see this model become internationalized to support multiple languages. **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** AssemblyAI enables me to efficiently convert large volumes of audio data into text, which is highly beneficial for both educational purposes and note-taking. ### 29. Easy Integration and Excellent Universal Pro Models **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in E-Learning | Small-Business (50 or fewer emp.) **Reviewed Date:** March 07, 2026 **What do you like best about AssemblyAI - Speech to Text API?** It's easy to use and integrate into my system, the universal pro models are very good **What do you dislike about AssemblyAI - Speech to Text API?** There were some minor problems with queuing/rate limiting even though I thought I never submitted more than 50 concurrent jobs **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** We're building a voice agent and AssemblyAI model is among the best so far ### 30. Best Speech-to-Text Service Overall **Rating:** 5.0/5.0 stars **Reviewed by:** Rodrigo F. | Consultant, Small-Business (50 or fewer emp.) **Reviewed Date:** May 19, 2025 **What do you like best about AssemblyAI - Speech to Text API?** AssemblyAI is seriously impressive. Before I found it, I tried out Google Cloud, Whisper, and some open-source tools for diarization. I even gave Read.ai a shot, but honestly, none of them gave me the results I was looking for. Then I saw someone mention AssemblyAI on Reddit, and I decided to give it a try. I’m so glad I did—their transcription and diarization are on another level. I barely ever need to edit the transcripts, which is rare with these kinds of tools. The pricing is super reasonable for what you get, and the API is really flexible. I’ve been able to build my own workflows to transcribe meetings, interviews, and videos without any hassle. I use it pretty much every day for transcribing meetings I record on my computer, and I save everything in Markdown format. If you’re looking for a solid, reliable transcription service that just works, I can’t recommend AssemblyAI enough. **What do you dislike about AssemblyAI - Speech to Text API?** It's not that I don't like but I think there is high bareer for non-techs to access the serviece. I know tht they ahve a playground, but it's still scary for peop,e who want to use the service but see the. Some friends who see my workflow wants to mimic but stop when they see the api nterface. The docs are very well detailed, but there are barreres for adoption for certain customer segments still. Another thing that I would like would to store the cluster of voicers that are recorded I would like the odel to automatically name them. I think this would be too complicated and probably there's privacy concerns involved. But it would be a quality of life approach. But I guess this is a niche need instead of something the custoemr base would be interested at **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** AssemblyAI is solving the problem of turning audio into accurate, structured text—especially with speaker diarization and high transcription quality. It saves me a huge amount of time. I use it to transcribe meetings, interviews, and video content recorded locally on my computer, and the results are so good I rarely need to edit them. Having access to a reliable API also means I can fully automate my workflow and store the transcripts in Markdown, exactly the way I need. It’s made transcription effortless and consistent, which is a big deal for someone who works with audio content daily. ### 31. Developer-Friendly and Accurate Transcripts **Rating:** 5.0/5.0 stars **Reviewed by:** Max M. | CTO, Small-Business (50 or fewer emp.) **Reviewed Date:** August 18, 2025 **What do you like best about AssemblyAI - Speech to Text API?** Beyond accurate transcripts, AssemblyAI made it easy to determine each call’s outcome, flag unqualified leads, and capture the exact reason a lead wasn’t qualified. Those structured insights rolled up into useful reports and metrics that our team could act on immediately. The whole process felt simple, reliable, and developer-friendly. **What do you dislike about AssemblyAI - Speech to Text API?** Using the default analysis was not that great, but once I figured out how to use LeMUR I got exactly what I needed. **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** Reviewing call recordings. Doing it manually is a very time consuming process. With Assembly AI I was able to create a process to review call recordings at scale and flag them for specific outcomes. ### 32. Quick Switch to Efficient, User-Friendly API **Rating:** 5.0/5.0 stars **Reviewed by:** Rohan P. **Reviewed Date:** August 04, 2025 **What do you like best about AssemblyAI - Speech to Text API?** I appreciate that AssemblyAI offers quick and accurate transcriptions, essential for maintaining compliance within our industry. The diarization feature is beneficial, providing clear speaker differentiation, which aids in compliance documentation. The user-friendly documentation made the setup process straightforward, which coupled with the appealing business insights and aesthetics of the platform, makes it enjoyable to use. The capability to seamlessly integrate with existing systems, like handling S3 links for file locations, significantly streamlines our workflow. **What do you dislike about AssemblyAI - Speech to Text API?** I find it problematic that the diarization feature does not differentiate between real human dialogue and automated call menus. It would be very useful if there were an option to ignore these automated voices or classify them separately, as they often appear as additional speakers in the transcription, which complicates the process for us. This issue requires us to manually remove irrelevant portions, which wastes time and effort. **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** I use AssemblyAI to accurately transcribe voice calls, ensuring compliance in our industry by documenting call details and enabling automated reporting, which is essential for our financial services. **Official Response from Devon Malloy:** > Thank you so much for your thoughtful review, Rohan! We're glad to be helping with your reporting automation needs. Your feedback about differentiating automated call menus from human speakers is super valuable—I've passed that insight along to our product team. If you have any additional context or details you'd like to share about your use-case, feel free to reach out to support@assemblyai.com to help us prioritize effectively. Devon ### 33. Accurate transcription, reasonably easy to integrate **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Internet | Small-Business (50 or fewer emp.) **Reviewed Date:** November 04, 2025 **What do you like best about AssemblyAI - Speech to Text API?** Assembly's accuracy is strong and on-par or better with many competitors in the space, especially after the launch of Slam-1. LLM Gateway is convenient for transcript summarization. Developer experience is largely strong with some exceptions. New feature releases continue demonstrating value. **What do you dislike about AssemblyAI - Speech to Text API?** Additional language support for Slam-1. Clearer documentation for more complex/specific workflows (Zoom + multichannel). Existing docs only explain how to implement in Python and support is having trouble helping us diagnose our issue. Out-of-the box speaker diarization and speaker labeling could be more accurate. **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** Speech-to-text transcription of live conversations. Higher accuracy than many out-of-the-box solutions (namely what's offered by Zoom). ### 34. a great solution to build into your product **Rating:** 4.0/5.0 stars **Reviewed by:** Timur M. | Developer, Small-Business (50 or fewer emp.) **Reviewed Date:** May 20, 2025 **What do you like best about AssemblyAI - Speech to Text API?** We recently started using the AssaemblyAI api to transcribe videos from our educational channels. The API works quickly and reliably. So far we have never encountered any limitations of the platform, although our videos are quite large. The quality of recognition is very high, the price is about the same as with OpenAI analogs, but there is no limit of 25 minutes per video fragment. **What do you dislike about AssemblyAI - Speech to Text API?** I wish the price was even lower, we have so many more videos to process. Also it is not quite clear how formatting into paragraphs works, according to the api we get exactly the text without paragraphs, although in the version available for free through the interface, the recognized text is already formatted **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** We are using the AssaemblyAI api to transcribe videos from our educational channels to build RAG system ### 35. High-quality speech recognition with robust diarization and smart API design **Rating:** 5.0/5.0 stars **Reviewed by:** Andrea R. | Manager, Small-Business (50 or fewer emp.) **Reviewed Date:** June 18, 2025 **What do you like best about AssemblyAI - Speech to Text API?** AssemblyAI impresses with its high transcription quality, even when dealing with messy or low-quality audio inputs. The diarization capabilities are particularly strong—accurately distinguishing between speakers in less-than-perfect recordings. The API suite is fast, well-documented, and returns a rich, detailed output format that makes post-processing straightforward and powerful. I also found the Word Boost feature especially helpful: being able to prioritize tricky or uncommon words significantly improves recognition accuracy in niche use cases. Overall, it’s a developer-friendly platform that balances precision with flexibility. **What do you dislike about AssemblyAI - Speech to Text API?** Honestly, there’s little to complain about. The pricing model is reasonable for the level of quality and features provided, and I haven’t encountered any significant drawbacks in my usage **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** Transcription and diarization of complex audios ### 36. Great Transcripts and Excellent Value, Even on the Free Plan **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Consumer Services | Small-Business (50 or fewer emp.) **Reviewed Date:** February 15, 2026 **What do you like best about AssemblyAI - Speech to Text API?** Great transcripts, amazing free option - really enhanced when you pay but value is there **What do you dislike about AssemblyAI - Speech to Text API?** Wish it could to text to speech outside of itself, twilio would be great. **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** Transcripting outbound/inbound calls for sales team ### 37. Much more affordable and accessible then other options **Rating:** 4.5/5.0 stars **Reviewed by:** Nick H. | Head of technology and marketing, Small-Business (50 or fewer emp.) **Reviewed Date:** April 09, 2025 **What do you like best about AssemblyAI - Speech to Text API?** One of the best things about AssemblyAI is how much more affordable and accessible it is compared to many other options on the market. The pricing is straightforward and budget-friendly, which makes it an excellent choice for both small developers and larger teams. Despite the lower cost, the transcription accuracy and feature set remain top-notch. The API is easy to implement, and the documentation is clear and helpful. It’s reliable, fast, and packed with features like speaker diarization and topic detection that are usually reserved for much more expensive platforms. **What do you dislike about AssemblyAI - Speech to Text API?** Currently there are some features not available to the European users but I believe these are in development. **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** We use it to transcribe conversations between brokers and clients, which ensures that key details aren’t missed and can be easily reviewed or referenced later. This is incredibly valuable for our brokers, who can focus on the conversation without needing to take extensive notes, then use the transcriptions to follow up with tailored advice or next steps. **Official Response from Madison Boyd:** > Thank you for your feedback! We are continuously working to expand our features to all users, including those in Europe. We appreciate your patience as we work on further development. ### 38. Great transcription for Spanish, quicker than other providers **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Financial Services | Small-Business (50 or fewer emp.) **Reviewed Date:** June 16, 2025 **What do you like best about AssemblyAI - Speech to Text API?** It's really great for Spanish specifically and user diarization. Also, it's quick compared to Speechmatics API; it's really slow, so kudos on that also, and it's been really cost-effective. I must have transcribed 800-1000 calls with the free credits, so that's really great. Overall super solid though. **What do you dislike about AssemblyAI - Speech to Text API?** I think the worst part about Assembly has been that the API itself is a bit complicated to work with, since with recordings you've got to make them into links first and then send the links and transcript IDs to a separate endpoint. I can still work with it and have done lots of things, but it would be easier if it was a single API if I'm working with recordings that did this in the background. **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** It is the only API we've found that reliably transcribes some of our more lower quality/foreign accents calls in Spanish with correct dieratization. We haven't found another API that did this well after trying most of the popular API's (e.g. deepgram, speechmatics) ### 39. Opens new doors for text analysis research **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Research | Small-Business (50 or fewer emp.) **Reviewed Date:** June 16, 2025 **What do you like best about AssemblyAI - Speech to Text API?** I'm an academic- I recently started using Assembly AI for a project I've been interested in doing for years. I just didn't have a good way to generate transcripts off of videos. Thus, I've been using it extensively over the past few weeks. I imagine it will be a case where I use it a lot in brief spurts over the coming months/years. I reached out with a question about academic use and was surprised by how quickly AAI responded (but, please recognize .edu as a valid work e-mail). I started working with Assembly AI on the free credits (which is a great way to "test drive"). It took me a while to get things just as I wanted, but once I got there, it has been smooth sailing and largely automated its integration into my research workflow. I've found the transcription quite accurate (this is the standard model, not the fancy new one). Processing time is fast- and everything is readily scriptable. There is rather nice documentation. **What do you dislike about AssemblyAI - Speech to Text API?** I think there are two things I would like to see in the future. First, I think the documentation is kind of balkanized. It would be nice if it was more streamlined. In my case, this really goes for formatting the output. More sample scripts for the output would be great. This would have made initial implementation a fair bit easier (I'd call it a 5/10 difficulty... and I'd call myself an ok-ish Python user). Second, I would like to see interruption/overlay detection. I get that might be hard without multiple microphones. For this one, I'm just going to hold out hope for the steady march of progress. **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** In my research, I'm keen to build transcripts for text analysis. I'm dealing with a corpus that isn't written down- it just exists as audio/video recordings. AAI is helping me construct those documents. I've always been excited by my research- but I am REALLY excited by where AAI can help me take it! **Official Response from Devon Malloy:** > Thank you for this thoughtful and detailed review—it's super rewarding to hear how our product is enabling and accelerating your research. Your feedback is extremely valuable, we've passed both items along to our support and product teams accordingly. Thank you for being part of our community and for pushing the boundaries of what's possible with STT! ### 40. A better tool then OpenAI APIs **Rating:** 5.0/5.0 stars **Reviewed by:** Kyle-Anthony H. | Video Editor, Small-Business (50 or fewer emp.) **Reviewed Date:** July 23, 2025 **What do you like best about AssemblyAI - Speech to Text API?** I loved the speed of the transcription and the token size. I was getting timeout errors in m applications despite much trouble shooting. But once I switched over, I was shocked by the speed! **What do you dislike about AssemblyAI - Speech to Text API?** There was bot much helpful documentation on using AssemblyAI in swift projects. I've been having much trouble figuring out how to set up AssemblyAi with Web-sockets for streaming input and output. **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** Its allowing me to reliably transcribe long form audio form sermon for Churches. Like mentioned earlier- the speed and audio length abilities are greater than other tools I've tried. ### 41. Accurate and reliable **Rating:** 4.0/5.0 stars **Reviewed by:** Nicolo L. | Founding Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** July 09, 2025 **What do you like best about AssemblyAI - Speech to Text API?** Accurate transcription, reliable service and great prices. It is easy to integrate, easy to use, and full of valuable insights for your audio **What do you dislike about AssemblyAI - Speech to Text API?** It only supports EU and US data residency. Regional self deployments would be great. Moreover, for companies that deal with both text and audio data, it would be useful to have the same pii redaction and insights for both data types, but AssemblyAI only accepts audio inputs, forcing us to try and replicate their pii redaction on text data through other means, or skip their pii redaction and insights for sake of uniformity. **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** Transcription of calls **Official Response from Devon Malloy:** > Thank you for the thoughtful feedback, Nicolo! We've shared your input with our product team—your insights on expanding data residency options and adding text processing capabilities are key to shaping our roadmap. In the meantime, please don't hesitate to reach out to our support team if you'd like to explore any workaround solutions. We appreciate you being a valued customer and taking the time to help us improve 😄 ### 42. Best-in-Class Speech-to-Text Solution **Rating:** 5.0/5.0 stars **Reviewed by:** Giorgio S. | CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** April 10, 2025 **What do you like best about AssemblyAI - Speech to Text API?** The exceptional accuracy, even with challenging audio and technical terminology, combined with their developer-friendly API that integrates seamlessly. Advanced features like speaker diarization and content moderation provide tremendous value beyond basic transcription. **What do you dislike about AssemblyAI - Speech to Text API?** Integration with complex database systems like VertexDB can be challenging and requires additional development effort. The response latency can sometimes be longer than expected, especially when processing large audio files, which can impact real-time applications that require immediate transcription results. **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** AssemblyAI is solving our critical need for accurate and scalable speech-to-text capabilities in our clone platform. By implementing their API, we've eliminated the resource-intensive task of developing our own transcription engine while gaining enterprise-grade accuracy. This has significantly accelerated our development timeline and allowed us to focus on our core platform features while providing users with reliable transcription services for audio content analysis and searchability.RetryClaude can make mistakes. Please double-check responses. ### 43.

Using AssemblyAI to get podcast episodes transcripts **Rating:** 4.5/5.0 stars **Reviewed by:** Francesco M. | Frontend developer, Small-Business (50 or fewer emp.) **Reviewed Date:** May 20, 2025 **What do you like best about AssemblyAI - Speech to Text API?** I use AssemblyAI to get transcripts of my podcast episodes, and the accuracy is pretty good. The timestamp associated with each word allow us to easily make a connection with the podcast audio and jump right where we need. Customer support has been great. **What do you dislike about AssemblyAI - Speech to Text API?** Nothing to complain. Sometimes it's a bit tricky when the podcaster say the spelling of the promo code he uses. For example, if the promocode is SUMMER. I may get S-U-M-M-E-R, which is not easy to work with. But I it's an edge case. **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** Get the podcast episodes transcript, associating each word with a timestamp. Give lot of insight to what podcasters are saying and how are promoting our promo codes **Official Response from Madison Boyd:** > We're thrilled to hear that our API is providing valuable insights for your podcast episodes.

Powerful and Accurate Speech-to-Text API **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Consumer Services | Small-Business (50 or fewer emp.) **Reviewed Date:** June 23, 2025 **What do you like best about AssemblyAI - Speech to Text API?** I love how AssemblyAI delivers outstanding transcription accuracy even on noisy or low-quality audio. The SDKs, documentation and code samples made integration into our codebase very easy and almost instantaneous. On top of all that, features like custom vocabulary tuning, topic detection, and sentiment analysis mean I can rely on a single platform for everything from basic transcripts to deep audio insights. **What do you dislike about AssemblyAI - Speech to Text API?** Occasionally the API struggles with heavy accents or extremely fast speech, leading to minor mis-transcriptions that require manual correction **What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?** AssemblyAI makes it possible to transcribe audio that other services struggle with, such as recordings with heavy accents, background noise or low volume. By delivering clean, accurate text from these challenging files, it eliminates the need for manual corrections and keeps our workflows moving smoothly. ### 48. Excellent advanced tool, but simple to use **Rating:** 5.0/5.0 stars **Reviewed by:** Emanuele D. | freelance, Small-Business (50 or fewer emp.) **Reviewed Date:** June 25, 2025 **What do you like best about AssemblyAI - Speech to Text API?** ...is a very comprehensive tool that not only allows for a very accurate transcription of the text, but also includes punctuation.
