**Reviewed by:** Verified User in Consumer Services | Small-Business (50 or fewer emp.)

**Reviewed Date:** June 23, 2025

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.

By delivering clean, accurate text from these challenging files, it eliminates the need for manual corrections and keeps our workflows moving smoothly.

  ### 3. Excellent advanced tool, but simple to use

**Rating:** 5.0/5.0 stars

**Reviewed Date:** June 25, 2025

  ### 4. High quality and Multilingual.

**Rating:** 4.5/5.0 stars

**Reviewed by:** Verified User in Market Research | Small-Business (50 or fewer emp.)

**Reviewed Date:** April 07, 2025

**What do you like best about AssemblyAI - Speech to Text API?**

I like the fact that it works in multiple languages, and then you can use speech dialization, and that it's pretty easy to set up in Python. on, I think, basically, the comprehensiveness combined with the simplicity of that API makes it a really great tool.

**What do you dislike about AssemblyAI - Speech to Text API?**

I think it's more that the tool is so simple that on the back end, There's a lot of things that you have to do as a user, perhaps, to get it exactly how how you want it. I think it would be good if there was more testing in the playground so that it didn't costs loads of money to better understand how to format things or to get things in a way that you most like how to use them.

**What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?**

I primarily use it for transcribing interviews and focus groups and things like that. and it's been super helpful to basically be able to add that to a pipeline of analysis.

**Reviewed by:** VIVEK P. | Performance Marketing Specialist, Information Technology and Services, Small-Business (50 or fewer emp.)

**Reviewed Date:** October 08, 2025

**What do you like best about AssemblyAI - Speech to Text API?**

  ### 6. Great Accuracy, but Diarization Can Be Inconsistent with Similar Voices

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.)

**Reviewed Date:** October 17, 2025

**What do you like best about AssemblyAI - Speech to Text API?**

High accuracy. The main reason we switched to AssemblyAI was that it support diarization out of the box. This feature gives a one stop ease of use.

**What do you dislike about AssemblyAI - Speech to Text API?**

The diarization can either work really well or really poorly. When the 2 voices are similar to each other it really struggles - when the voices are different it's accuracy is much better. This means we have to put in an extra step to diarise in case it fails.

**What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?**

Can analyse many calls to check that points are been hit as required by the business

  ### 7. Accuracy is paramount! AssemblyAI meets that standard.

**Reviewed by:** Scott J. | Chief Investment Officer, Small-Business (50 or fewer emp.)

**Reviewed Date:** September 01, 2025

I don’t have one complain. It works flawlessly and as described.

I use a local machine to transcribe speech and match the results with assemblyAI to increase accuracy.

  ### 8. Great, cost effective solution

**Rating:** 4.5/5.0 stars

**Reviewed by:** Darko D. | Chief Operations Officer, Mid-Market (51-1000 emp.)

**Reviewed Date:** August 11, 2025

There is nothing that we dislike. It is easy and super intuitive product that matches our exact needs.

**What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?**

Coaching our SDR team.

  ### 9. Accurate and Cheap!

**Rating:** 5.0/5.0 stars

**Reviewed by:** Austin V. | Creator/Host, Small-Business (50 or fewer emp.)

**Reviewed Date:** August 06, 2025

**What do you like best about AssemblyAI - Speech to Text API?**

Assembly AI is hands down the fastest, cheapest, and most accurate transcription service I've used. The word-level timestamps are very precise.

**What do you dislike about AssemblyAI - Speech to Text API?**

For my use cases, I would love to see the speed of transcription improve to less than 5 seconds per hour of content.

**What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?**

Transcribing podcasts at the time of playback.

  ### 10. OK Transcription, But Latency and Async API Need Improvement

**Rating:** 2.5/5.0 stars

**Reviewed by:** Verified User in Information Technology and Services | Mid-Market (51-1000 emp.)

**Reviewed Date:** November 22, 2025

**What do you like best about AssemblyAI - Speech to Text API?**

Marketing seems like it's focused on conversational STT use cases -- short utterances, proper nouns

**What do you dislike about AssemblyAI - Speech to Text API?**

Latency, async batch endpoint -- not great for real-time conversations. I found that if I submit a full audio file (1 min) to the endpoint, it does ok but if I replay the audio chunk by chunk, similar to a real conversation, the transcription quality decreases dramatically

**What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?**

Still benchmarking on proper nouns and short utterances

**Official Response from Lee Vaughn:**

> Thank you for sharing your feedback with us!

The behavior you are describing is somewhat expected. When you submit the entire file, the model is able to take the full context of that audio into account, which will improve overall accuracy. But when you submit just a chunk of the audio, like a single sentence or utterance, the model only has that small amount of context to draw from, which can affect accuracy.

That said, there could be ways to improve the results you are seeing, including using our Streaming STT feature, which is optimized for real-time use cases, instead of the async STT feature. If you would like to reach out to us at support@assemblyai.com we would be happy to dig more into the results you are seeing and how they can be improved.

Thanks!

**Reviewed by:** Verified User in Market Research | Small-Business (50 or fewer emp.)

**Reviewed Date:** April 09, 2025

**What do you like best about AssemblyAI - Speech to Text API?**

The documentation is fairly clear, and there's a lot of good libraries to get you going.  If you're using any tech stack, or just want to roll your own connection, it's pretty clear what you need to do.  Of the several different integrations I'm working with at the moment, this one is the easiest.

**What do you dislike about AssemblyAI - Speech to Text API?**

Getting to the API documentation is actually not as easy as I'd like.  Because everything seems to run so smoothly, I don't have to work with AAI too often, it just does the job.  So when I do need to alter something in my usage, I do need to work out how to get to the API documentation.  Minor issue, but it something I think about every time I use it!

**What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?**

We want transcription for videos.  This does exactly what we need.

The documentation is great, and the WER is best in class. The integration was so smooth as it's compatible with all popular vendors

**What do you dislike about AssemblyAI - Speech to Text API?**

The platform itself isn't mature, has no team management, and no basic features for organizations

**What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?**

The WER for live vidoes generation

  ### 16. Actually best tool for translate speech to text

I tried to have speech to text with other way for example a personal server with Whisper

  ### 17. A cutting edge speech to text service

**Rating:** 4.5/5.0 stars

**Reviewed by:** Verified User in Market Research | Small-Business (50 or fewer emp.)

**Reviewed Date:** April 14, 2025

**What do you like best about AssemblyAI - Speech to Text API?**

There were 2 things we were looking for when evaluating speech to text APIs:
1) Quality of the speech to text (the most important thing)
2) Speed of the speech to text
3) Documentation / ease of use.

And after using this service for a few months now, AssemblyAI knocks all 3 out of the park.

**What do you dislike about AssemblyAI - Speech to Text API?**

The one thing we are having slight issues with is speaker diarization with more than 10 speakers. Honestly, it's a bit of an edge case, but something it doesn't do great with all the time. Anything under that though hasn't been an issue, and that's the vast majority of our use case

**What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?**

It creates transcripts for video interviews we conduct on our site.

  ### 18. Accurate and easy to use

**Rating:** 4.0/5.0 stars

**Reviewed Date:** September 22, 2025

**What do you like best about AssemblyAI - Speech to Text API?**

Speed of async transcription and the quality of the transcript

**What do you dislike about AssemblyAI - Speech to Text API?**

Diazarization needs improvement, and we need streaming available in EU for all European languages.

**What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?**

Taking notes of the meeting, and giving us action items

  ### 20. Great product. Great fidelity.

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Higher Education | Small-Business (50 or fewer emp.)

**Reviewed Date:** October 01, 2025

It is remarkably accurate, even if the audio quality (as assessed by this researcher) is below what might be expected.

**What do you dislike about AssemblyAI - Speech to Text API?**

The diarization feature sometimes fails.

**What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?**

  ### 21. Works well

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.)

**Reviewed Date:** April 11, 2025

**What do you like best about AssemblyAI - Speech to Text API?**

It works well and is pretty accurate in usage. Using LeMUR summaries is great and works well but needs a defined prompt based on the use case. Can return multiple formats which is great. LeMUR responses return fairly quick and are easy to set up.

**What do you dislike about AssemblyAI - Speech to Text API?**

Takes a moment to start up and sometimes punctuation could be better, it  often breaks sentences up into smaller bits.
Setting up websockets for streaming is quite difficult due to many parts.

**What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?**

In our use case, it allows our financial advisers to have a natural conversation with a client and transcribe the whole thing. With lemur summaries we can prompt to answer specific information from the meeting.

It accurately transcribes and diarizes every single transcript I throw at it

**What do you dislike about AssemblyAI - Speech to Text API?**

I think this is a fantastic solution, there's not many issues I have with it. Maybe if they improve the diarization algo, sometimes it merges speakers together

**What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?**

It has made the process of transcribing my meeting audio so simple and straightforward. I have all of those transcription being fed to an Agentic RAG tool, which has unlocked crazy new business value for me.

Extremely easy to implement the api into any code

**What do you dislike about AssemblyAI - Speech to Text API?**

**What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?**

Taking audio and transcribing it into text. As well as all the timestamps of when the audio was said etc...

It’s easy to implement and delivers great value for money. The way the API is designed is excellent!

Difficulties with multiple speech detection with people with English accent. I wish there was a calibration feature for individual voice.

I use it for notes recording and conversations. Easy to record whole length of conversation and apply backend algorithm to brief the conversation details due to accuracy of recording.

I am a college professor and used the AssemblyAI speech-to-text API for a qualitative research project. I had hundreds of interviews in a non-English language that needed to be transcribed.

I could not be happier.

  ### 42. Overall, the Perfect Product!

**Rating:** 4.5/5.0 stars

**Reviewed by:** Jacob S. | Founder/Software Developer, Small-Business (50 or fewer emp.)

**Reviewed Date:** June 21, 2024

**What do you like best about AssemblyAI - Speech to Text API?**

Assembly has been the go-to for our business for all things Speech to Text related. We love the ease-of-use with integration, extremely clear documentation (implementation), phenomenal support, and accuracy of the speech to text recognition.

Assembly has kept up with our startup's high volume of requests. We grew quickly from 0-180,000 users within 7 months and used Assembly from our very first MVP into our full scale production versions now. We have had practicaly no issues throughout this process - and if we did - support was quick to provide a solution.

In addition to all of the above, the price for the product is perfect.

**What do you dislike about AssemblyAI - Speech to Text API?**

They are limited in the number of languages they offer. While I haven't done extensive competitor research, I believe that others may offer more language variety which we would greatly benefit from in our app.

The other downside is the number of customizable outputs from the API. We wanted our Speech to Text output to deliver us an SRT file that only displays one word at a time on the screen (since this is a popular format on social media). Assembly does not support these kinds of customizations - however, they did offer a solution for this that requires custom code post-processing of the API call which we appreciated. 

Therefore, while there are a few small drawbacks, we have been able to accurately deliver speech-to-text recognition to our 180,000+ users thanks to Assembly.

**What problems is AssemblyAI - Speech to Text API solving and how is that benefiting you?**

They recently added speaker diarization which is great and will benefit our product. They also added new languages recently which we now can also provide to our users (which we appreciate). In addition to this, they told me they are also improving the languages they currently support as well. This is helpful because we have had some users experience inaccuracies with their STT.
