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 challenges persist despite audio technology advancements
Google Cloud Speech-to-Text is not entirely accurate, so we have to correct for those errors in our AI software. It uses neural networks, and that stochastic processing is 70% to 75% accurate. It gets it wrong too often, and since I personally work with this, I don't appreciate that. However, they seem to be the best option currently. We have to write our own improvements because their tools to improve transcription accuracy in our domain aren't very powerful. The timestamp technology for recognized words is inadequate, so we don't use it. We understand words based on their meaning, and we have a whole AI engine that does that, which is one of our differentiators from a product standpoint. We didn't use the custom voice creation feature; we just use their voices, which are fine for our purposes.

Quotes from Members

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

Pros

"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 speed of the solution for transcribing videos is good."
"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 features that I have been using in the tool have been very stable."
"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."
"Deepgram is able to handle large volumes of audio data without compromising accuracy."
"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."
"I would suggest Google Cloud Speech-to-Text to others, primarily for the speaker diarization feature."
"The implementation is simple, and the outputs are very accurate and crisp."
"During the time I used Google Cloud Speech-to-Text, it was very impactful to the organization as it made our tasks much easier to perform."
"Google Cloud Speech-to-Text helps to keep my team more productive."
"You could dictate a bunch of stuff, and then you can get ChatGPT or something to clean it up."
"We've found the solution scales well."
"Google Cloud Speech-to-Text sounds incredibly natural, which is impressive."
"The product's initial setup phase is very easy."
 

Cons

"The solution does not properly identify the number of speakers."
"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."
"The traditional Speech-to-Text doesn't understand when the user is done speaking in bot conversations."
"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."
"I would like it to be more accurate."
"Deepgram is currently restricted to only the English variants, but it should include other languages, such as German or French."
"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."
"Google Cloud Speech-to-Text is 100 out of 100 when it works, and when it doesn't work, which is fairly often, it gets a zero. It doesn't fail gracefully; it fails in an unexpected way."
"The one thing that I find is when I often use specialized terms, and the solution doesn't know them."
"The multilanguage support for the chatbot needs to be better."
"Given the numerous accents and dialects in India, Google Cloud Speech-to-Text could improve its handling of Indian accents."
"Since it is a paid service, it is very difficult to access if a user does not have the credentials. Also, we have to create the API keys and secret keys repeatedly to maintain authentication and privacy."
"Sometimes, speaker diarization is affected, leading to incorrect speaker identification."
"Google Cloud Speech-to-Text's trial experience could be improved by adding some extra minutes in the trial version."
"The tool's telephony model does not produce accurate results."
 

Pricing and Cost Advice

"The pricing is moderate."
"When using Deepgram, one needs to pay for the hours or minutes for which the transcription is needed."
"The solution’s pricing is cheap."
"Deepgram is a cheap solution."
"Cost-wise, I would say it is all-inclusive in the payment made to Google."
"The tool's cost is also very low. The tool is cheaply priced. It charges around 0.13 INR per call with a duration of five minutes."
