A Powerful, Adaptable, and Constantly Evolving STT Solution for Voice Automation
Honestly, Deepgram has been exceptionally proactive in addressing the primary area that needed improvement. My main challenge was with the real-time detection of when a user has finished speaking in a live conversation, which is critical for a responsive voice bot. They directly solved this by releasing their Flux model. Because Flux is a recent release, I haven't yet had enough time to thoroughly test it and identify new limitations. At this stage, any "improvement" would be more of a "nice-to-have" feature rather than a fix for an existing problem. The core service is already very robust and meets all of our current needs. What additional features should be included in the next release? ---------------------------------------------------------------- Looking toward the future, here are a few features that could add even more value to an already excellent platform: * Advanced Built-in Analytics: While I can get the raw transcript and build my own analytics pipeline, it would be powerful to have features like sentiment analysis, emotion detection, or automatic summarization offered directly through the API. This would save significant development time. * More Granular Speaker Diarization: For calls with multiple participants, enhancing the real-time speaker diarization (labeling who is speaking) to be even more precise would be a fantastic addition for creating detailed call analyses. * Tighter Integration with TTS: Since Deepgram is also expanding into Text-to-Speech (TTS), offering a more seamlessly integrated STT-to-TTS pipeline could simplify the development stack for creating voice agents from start to finish. * Specialized, Pre-Trained Industry Models: While the general models are highly accurate, offering even more specialized, pre-trained models for specific industries like finance, healthcare, or legal-which are heavy on specific jargon-could push the accuracy even higher for those niche use cases.

Support issues overshadow solid features in daily operations
The support is inadequate. We are dealing with them on our development talk today. There's a lot of finger-pointing going on in terms of whose problem it is. Moving our stuff up to the Google Cloud and getting it to work just as well as it does on people's development machines is problematic. Their support for that, even though we paid for it, isn't really very helpful. That's prevalent in the computer business. You need to have your own experts, otherwise you're really in trouble. The product is an eight out of 10. The support is at best a five. We have to write certain features ourselves because their offerings aren't very powerful. When I don't have a problem, it works pretty well, better than anybody else. But when I do have a problem, I'm severely impacted. It takes a lot of time and money to go back and fix it. What has gotten better with Google Cloud Text-to-Speech is their stuff sounds so natural, it really brings a smile to my face. I wish their support would be better.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The best thing with Deepgram is they are continually evolving and doing a lot of market research, and they take feedback seriously."
"Deepgram's low latency transcription has greatly impacted my ability to deliver reliable voice agents and provided very good transcription."
"The features that I have been using in the tool have been very stable."
"Deepgram's transcription stands out compared to other solutions primarily due to its speed and accuracy; those are important points for me because not all providers or tools handled Spanish well, but Deepgram adjusted perfectly for that use case, and we also chose 11Labs voice, a South American voice, which worked very well with Deepgram."
"Deepgram is able to handle large volumes of audio data without compromising accuracy."
"The recognition of industry-specific terminology phrases and abbreviations is really important for us. We were able to get a good level of industry specificity with Deepgram."
"The speed of the solution for transcribing videos is good."
"The most valuable capabilities of Deepgram that I've found so far include low latency, as it offers less than 200 milliseconds, which is not provided by any other text-to-speech models."
"Precision is the most valuable feature of Google Cloud Text-to-Speech because the text is perfectly voiced."
"What has gotten better with Google Cloud Text-to-Speech is their stuff sounds so natural, it really brings a smile to my face."
"It's not complex to set up."
 

Cons

"We haven't seen a return on investment with Deepgram so far; we have been building POCs for the last two years but recently switched to AWS in the last two months due to scalability issues with the pay-as-you-go model."
"The solution does not properly identify the number of speakers."
"The area of live transcription could be improved. Sometimes, Deepgram's WebSocket is disposed due to redundancy."
"Deepgram is currently restricted to only the English variants, but it should include other languages, such as German or French."
"I would like it to be more accurate."
"Even though Deepgram has many customization options, I wish that Deepgram had voice cloning customization to a much larger extent."
"We've had issues in the past where it generates the transcript, and a lot of the text is duplicated."
"The traditional Speech-to-Text doesn't understand when the user is done speaking in bot conversations."
"Google Cloud Text-to-Speech has just one female voice and one male voice in Brazil, while it has a lot of voices in other countries."
"Google Cloud Text-to-Speech is 100 out of 100 when it works, and when it doesn't work, which is fairly often, it gets a zero."
"We had some problems with Dialogflow."
 

Pricing and Cost Advice

"The pricing is moderate."
"Deepgram is a cheap solution."
