Featured Reviews

Mihir Jadhav - PeerSpot reviewer
Software Engineer at Futurescape Technologies
Voice agents have automated support and now handle customer queries with lower latency
Deepgram has a vast UI and a vast range of models, but there could be a simpler version for creating AI agents rather than providing a full-fledged platform for minimal use cases. It could be multilingual, as in India, there are multiple several languages. If it had support for many more languages, especially regional languages, it would be valuable.

Facilitating seamless international communication through efficient transcription and translation tasks
The product is limited when it comes to integrating with different platforms and using many other APIs. The marketplace is very limited and it's difficult to implement solutions in it. Enhancing features by integrating with other AI solutions like Gemini and Menus, as well as improving communication across platforms, would make it a more comprehensive solution.

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."
"We have tracked a reduction of around 70% in the support cost and direct human interaction for support."
"The ROI has been excellent; the cost is night and day compared to the cost of human transcription, and we're spending maybe a tenth of the cost we would if we were still doing manual transcriptions."
"Deepgram has significantly improved our transcription process in terms of speed and accuracy, allowing us to efficiently convert verbal feedback into text, enabling quicker analysis and implementation of new features."
"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."
"The solution's most valuable feature is its speed of transcription, as it is one of the fastest tools, especially if you compare it to the second fastest solution that you can get, which is 20 times faster, so it is not just a marginally faster product."
"The best features of Deepgram for me are the level of transcription accuracy it provides and the amount of time it saves."
"The documentation and boilerplate code [a template of code] was available."
"Useful text-to-speech and speech-to-text features."
"Overall, in my opinion, the transcription service is rated as ten out of ten."
 

Cons

"The solution does not properly identify the number of speakers."
"When I had an AI interview for coding, Deepgram didn't capture the names of programming languages or well-known LLMs accurately all the time."
"The traditional Speech-to-Text doesn't understand when the user is done speaking in bot conversations."
"Deepgram has a vast UI and a vast range of models, but there could be a simpler version for creating AI agents rather than providing a full-fledged platform for minimal use cases."
"Even though Deepgram has many customization options, I wish that Deepgram had voice cloning customization to a much larger extent."
"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."
"I would like it to be more accurate."
"I would not recommend Deepgram to other users because it does not properly identify video communication."
"The product is limited when it comes to integrating with different platforms and using many other APIs."
"It can improve based on the native language."
"Lacks a voice recording option."
 

Pricing and Cost Advice

"Deepgram is a cheap solution."
"When using Deepgram, one needs to pay for the hours or minutes for which the transcription is needed."
"The solution’s pricing is cheap."
"The pricing is moderate."
