"Fast, Developer-Friendly Voice API for Real-Time Transcription and Tutoring"
5/5
What do you like best about Deepgram?

What I like best about Deepgram is how fast and developer-friendly it is. The low-latency streaming transcription makes real-time voice features feel natural, and the API is simple enough that I could get a working prototype running quickly. For STEMBridge, that matters because we’re students building with limited time. I also like that you can customize it with keyword boosting, which helps with technical STEM vocabulary, and that it now covers text-to-speech and voice agents, so we could build a full voice-based tutoring experience in one place. Review collected by and hosted on G2.com.

What do you dislike about Deepgram?

What I like least about Deepgram is that it’s closed and proprietary, so unlike Whisper we can’t self-host it or inspect it, and we depend on their pricing and product decisions. The free credits are great for prototyping, but costs could add up once a tutoring platform has lots of audio hours, which matters for a student-run nonprofit. Language coverage is also narrower than Whisper’s, so it may not serve students who speak local languages. And like most speech models, accuracy can drop with heavy accents or background noise, so we’d want to test it on realistic recordings before committing. Review collected by and hosted on G2.com.

"Fast, phone-ready speech to text that keeps getting better"
4.5/5
What do you like best about Deepgram?

We use Deepgram's streaming API as the ears of an in-house AI phone agent that answers calls for a car transport business. It takes the raw 8 kHz phone audio straight off the line, no converting, and turns it round in under a second, which is what makes a live conversation feel natural. The API is simple to wire up, it's been reliable in production, and it's a small part of our cost per minute. When we compared nova-3 with the older phone-call model on 24 real recorded calls, nova-3 got noticeably more Australian town names right (Kalgoorlie, Kempsey, Archerfield) at the same speed and a lower price. Review collected by and hosted on G2.com.

What do you dislike about Deepgram?

Short words on a phone line are still hit and miss. "Quote" comes out as "card" or "quarter" every so often, on both models. There's no setting to ignore a second voice or background noise in the caller's room. Moving to nova-3 also meant changing how we pass hint words, because it rejects the old keywords option. That was easy enough, but it would have been nice to see it flagged more clearly. And speaker labels on streamed phone calls haven't been useful to us. Review collected by and hosted on G2.com.

"HIPAA-Eligible Transcription with Custom Vocabulary That Streamlines Clinical Documentation"
4/5
What do you like best about Deepgram?

Deepgram’s HIPAA-eligible real-time transcription and custom vocabulary model are what I value most as I manage clinical workflows at Pinnacle Behavioral Collective. In my role as Clinical Operations & Stakeholder Partnership Manager, I coordinate group therapy sessions, oversee contract therapists, and handle secure documentation for our outpatient mental health clinic. Our team records telehealth and in-person group sessions only with written patient consent, turning conversations into notes for care planning and supervision reviews. Before adopting Deepgram, our therapists manually jotted session takeaways during meetings or spent hours afterward listening back to audio recordings and typing summaries. This pulled focus away from active patient engagement and created a massive backlog of unfinished clinical documentation.

The custom vocabulary tool has been transformative for our work. Behavioral health conversations are filled with specialized terminology: diagnostic labels, evidence-based intervention names, local support resource codes, and unique patient aliases we use to protect privacy. I upload a glossary tailored to our clinic’s practice, and Deepgram trains itself to recognize these terms consistently. During a recent eight-session dialectical behavior therapy (DBT) group, the transcription captured terms like “wise mind” and “skill chain” without constant misspellings that plagued our older transcription tool. Our licensed therapists no longer pause to correct dozens of terminology errors, cutting their post-session editing time significantly each week.

I also rely heavily on its speaker diarization feature, which separates speech by individual participant. Group therapy often includes multiple patients, a lead therapist, and sometimes a student observer. The labelled speaker tracks let me quickly isolate commentary from our contract therapists for peer supervision, without scrubbing through the whole audio file to locate their feedback. Since we operate under strict HIPAA rules, I appreciate that we can enable end-to-end encryption and lock down data retention settings to auto-delete raw audio files after transcripts are finalized. This removes a big compliance worry our small team carries, especially without an in-house IT specialist to audit data handling.

An unexpected benefit I uncovered is how the timestamped transcripts simplify quality assurance checks. When our clinical leadership team reviews session fidelity for CBT protocols, we jump straight to timestamps where specific interventions should have been introduced, rather than listening through full 90-minute recordings. This streamlined our monthly supervision cycle and helped us spot opportunities for therapist coaching faster.

Deepgram still requires careful access controls, as every transcript holds sensitive patient information, and it does not feed directly into our EHR system. I export finalized, redacted transcripts manually for chart integration. Even with this extra step, its accurate, privacy-focused transcription stack lightens the documentation burden on our clinicians. Therapists can stay present with patients during sessions instead of rushing to capture notes, which aligns perfectly with our core priority of delivering thoughtful, uninterrupted behavioral care. Review collected by and hosted on G2.com.

What do you dislike about Deepgram?

For our behavioral health clinic, Deepgram’s core transcription engine delivers solid results, but gaps in speaker separation, native EHR connectivity, and built-in PHI scrubbing create persistent operational headaches that eat into my bandwidth as Clinical Operations & Stakeholder Partnership Manager at Pinnacle Behavioral Collective. Our lean team manages group therapy and one-on-one telehealth sessions, and without dedicated IT support, every manual workaround adds risk and slows our clinical documentation cycle.

Speaker diarization is the most frequent pain point. Group therapy naturally overlaps, with patients talking over one another, pausing, or offering quiet, hesitant responses. Deepgram often merges multiple participants under a single speaker label or misassigns therapist commentary to a patient. During a recent DBT skills group with seven attendees, nearly 30% of the transcript lines had incorrect speaker tags. My contract therapists spent extra time splitting and relabeling segments before supervision reviews; this manual correction work can take an hour for a single 90-minute recording. The tool does not offer a simple way to lock speaker identities mid-transcript, so fixes do not carry over to future uploads from the same recurring group.

I also struggle with its limited native integration with our behavioral health EHR. Deepgram functions largely as a standalone transcription API, with no pre-built connector for common mental health charting platforms. Once a transcript is finalized, our team must manually export, redact, and paste relevant excerpts into patient charts. For our clinic, this is more than an inconvenience: every copy-paste step introduces accidental PHI exposure risk. I have to audit every exported file separately to remove nicknames, hometown references, and identifying details the automatic redaction misses. Its native redaction tool only catches standard fields like phone numbers and dates of birth; it cannot recognize context-sensitive identifiers unique to our therapy sessions.

The custom vocabulary workflow carries hidden friction as well. While the glossary helps with standard clinical terms, it does not retain context for softer, conversational phrasing common in counseling. Slang, regional speech patterns, and fragmented patient speech regularly get misinterpreted, and batch editing these errors line by line adds up quickly. There is no option to save session-specific correction rules to apply automatically for the same patient cohort across follow-up appointments.

An unexpected downside I’ve encountered ties to access governance. The platform’s permission model only offers broad editor or viewer roles. I cannot create a restricted access tier for contract therapists, one that lets them upload their own session audio and view only their assigned transcripts. If I grant upload access, they can potentially see files for other providers’ patient groups. That forces me to handle every upload myself, creating a transcription backlog when I’m pulled into referral coordination or vendor check-ins.

Deepgram is built around generic voice-to-text use cases rather than the nuanced privacy and documentation rules of outpatient behavioral care. It produces usable transcripts, but the constant need to fix speaker labels, scrub sensitive context manually, and guard access slows our clinical team down. Until these clinic-specific workflows are refined, Deepgram remains a tool that demands consistent oversight rather than a seamless fit inside our HIPAA-aligned care pipeline.

"Deepgram: Fast, Developer-Friendly, and Great for Domain-Specific Vocabulary"
4/5
What do you like best about Deepgram?

Deepgram is really a developer-friendly solution and is extremely fast if you compare it against other vendors like OpenAI Whisper and Speechmatics. I mention friendly because I never had to reach out to support to get the integration working, is pretty easy, well-documented, and self-explanatory. Something that caught my attention about making the switch is the ability to train domain/industry specific vocabulary; this is very useful when you need to focus your solutions in the industry, reducing friction for the final user. Review collected by and hosted on G2.com.

What do you dislike about Deepgram?

There is a big data privacy trade-off. If you leave the Model Improvement Program that uses the audio data to train their models, you lose the 50% rate discount, this is bad for FinTech startups, where money is a valuable asset that you need to take care of, but as a highly regulated industry, you can't share your data easily; the previous thing combined with the modular pricing means that the cost add up quickly when you need advanced features.

"Fast and Accurate Transcription with Deepgram, Easy Integration and Flexible Models"
4/5
What do you like best about Deepgram?

What I love most about Deepgram is the accuracy and speed with which it transcribes. I've tried other solutions and always missed some details, but with Deepgram, I feel the result is much more reliable. Additionally, the integration is simple, and the platform is very intuitive, allowing me to focus on my work without wasting time configuring things. I also highlight the flexibility of its models, which adapt well to different accents and contexts. In summary, it gives me peace of mind knowing that I can rely on a tool that truly understands what is being said. Review collected by and hosted on G2.com.

What do you dislike about Deepgram?

What I like least about Deepgram is that, although the accuracy is very good, it can sometimes be a bit difficult to adjust the models for very specific cases or when there is technical jargon. I would also like the documentation to be clearer in some points, because at first, I had to spend extra time to fully understand how to take advantage of all the features. These are not serious problems, but details that could be polished to improve the experience and make it even smoother. Review collected by and hosted on G2.com.

"Fast, Affordable Voice AI with Great Support—Room to Improve Voices"
4.5/5
What do you like best about Deepgram?

I find Deepgram cheap, but that doesn’t mean it performs poorly—the voices are actually great, and the latency is amazing for voice assistant work. I love the text-to-speech, and the voices are pretty good. The free limits are generous, and the credits I get as a student are pretty good. I also like the speed, cost, support, and developer experience. Even though the Discord server is a bit quiet, Naomi and Greg are available, and they listen to feedback and work on it. I shared feedback about Indian-accent voices, and they listened. Setup was pretty easy, and the same thing works for everything. Deepgram is my first choice. Review collected by and hosted on G2.com.

What do you dislike about Deepgram?

I’d like more voice options and better accents so the voices feel more natural. I’d also like block support for expressing emotion, like using [serious] to make a voice sound serious. I’m not sure whether that’s supported now. Review collected by and hosted on G2.com.

"Lightning-Fast and Affordable, but Irish Accent Accuracy Lags"
4/5
What do you like best about Deepgram?

I mainly like the speed of Deepgram Flux. Its response time is around 250 milliseconds for me, and having it available in the UK or Ireland helps compared with the US-based models I used before. It has helped with response times for my AI receptionists, and it’s quite cheap to use. I also find that integrating it with Telnex works better for me. Review collected by and hosted on G2.com.

What do you dislike about Deepgram?

I find Deepgram Flux isn’t as accurate as other models in my benchmarks and testing, especially with Irish accents—not necessarily the Irish language, but the accents used in Northern Ireland and Ireland. I feel Deepgram has fallen slightly behind Assembly AI, which seems to have improved on this recently, and I might have to move to Assembly AI at some point.

"High-Quality Voice API with Effortless Setup"
5/5
What do you like best about Deepgram?

I find Deepgram's API reliable, quick, and high quality. The voices are really high quality and help make interviews and video narrations feel human. I use the text-to-speech API for narrations and voice-to-voice for interviews. The $200 in free credits made it easy to get started and was really valuable. Setup was extremely easy, maybe the easiest of all the APIs I've hooked up. I was impressed that I could build my own solution and use Deepgram with Daily Pipecat, and it stood out as a high-quality, low-cost text-to-speech option. Review collected by and hosted on G2.com.

What do you dislike about Deepgram?

I don't really have any complaints. AI models keep leapfrogging each other, and OpenAI's Live API seems impressive and more like true voice-to-voice, while Deepgram seems more like speech generated from text, though I could be wrong. I'd just suggest continuing to improve. Review collected by and hosted on G2.com.

"Simple Integration, Natural Voice, and More Speed"
4.5/5
What do you like best about Deepgram?

I like the ease of integrating the agent: I manually configure it on the Deepgram dashboard and then just need to integrate it into my code. The documentation is very explicit and facilitates adjustments for the agent to have a more humanized behavior. I really like the naturalness of Nova 3 in identifying speech and then transcribing it. The voice functionality of my agents works extremely well. Speaking is more natural and helps save time; I can also send prompts by voice to my code agent much faster. The initial setup was very easy and I had no problems. Review collected by and hosted on G2.com.

What do you dislike about Deepgram?

I couldn't find a Deepgram TTS model that speaks European Portuguese, so I use ElevenLabs to get the voice. It would also be fantastic to have a "speech" model and receive some feedback while the LLM model is thinking, like "hmm...", "okay, I see". Review collected by and hosted on G2.com.

"Accurate, Affordable Transcription with Easy API Setup"
5/5
What do you like best about Deepgram?

I think Deepgram’s pricing is very fair, and the 200 euro or dollar credit I got when I signed up is still far from running out. I think its transcription quality is way better than some other tools I’ve tried, especially compared to local transcription and the built-in transcription in LLM tools. I appreciate being able to have my data processed in an EU data center, and I like that the API lets me plug transcription into the apps I want, including Open Whisper. Setup was very easy: I just created an API key and put it into Open Whisper. Review collected by and hosted on G2.com.

What do you dislike about Deepgram?

I don’t think I’ve found anything to complain about with Deepgram. The transcription quality could always improve, though I feel it’s already at a very good level. I tried the text-to-speech API and it worked okay, but I don’t really have a use case for it, and I feel like other tools such as ElevenLabs are better on that front. I haven’t tested it much, so I might be wrong. Review collected by and hosted on G2.com.
