Arunkumar HG - PeerSpot reviewer
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.

A stable solution that is used to vocalize the text written on the API to the client
We use Google Cloud Text-to-Speech when we have an IVR and need to say something written on the API through the IVR. For example, if I'm on the IVR and need to say something to the customer that is written on the API, I need to vocalize this text. I use Google Cloud Text-to-Speech to take this text…

Quotes from Members

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

Pros

"Deepgram's low latency transcription has greatly impacted my ability to deliver reliable voice agents and provided very good transcription."
"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."
"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 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."
"Deepgram is able to handle large volumes of audio data without compromising accuracy."
"The features that I have been using in the tool have been very stable."
"The solution's Speech-to-Text conversion feature is really awesome."
"The best thing with Deepgram is they are continually evolving and doing a lot of market research, and they take feedback seriously."
"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."
"Precision is the most valuable feature of Google Cloud Text-to-Speech because the text is perfectly voiced."
 

Cons

"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."
"We've had issues in the past where it generates the transcript, and a lot of the text is duplicated."
"The solution does not properly identify the number of speakers."
"The traditional Speech-to-Text doesn't understand when the user is done speaking in bot conversations."
"Deepgram is currently restricted to only the English variants, but it should include other languages, such as German or French."
"Regarding improvements for Deepgram, I think the quality of the transcriptions could be enhanced, as the Spanish accent poses challenges, making it harder to transcribe some words, and considering additional accents from Chilean or Argentine speakers could improve the model's performance with local words."
"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."
"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."
"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."
 

Pricing and Cost Advice

"When using Deepgram, one needs to pay for the hours or minutes for which the transcription is needed."
"The pricing is moderate."
"The solution’s pricing is cheap."
"Deepgram is a cheap solution."
"I rate Google Cloud Text-to-Speech three out of ten for pricing."
