Review Deepgram?

Reviewers mostly praise Deepgram for fast, accurate transcription and low-latency performance, with several users also calling out easy APIs, strong speaker diarization, and useful voice generation. The sentiment is consistently positive, especially around real-time and scalable speech work. A few makers of products built on it, including Daily.co, Vapi, and Shimmer ADHD, endorse it too, but they provide no extra detail. The main criticism is narrower: some users want better text-to-speech accuracy and improved multilingual detection.

We use Deepgram to transcribe live AI-driven training calls, where SDRs and sales reps practice conversations with an AI agent impersonating real prospects. The fast, accurate transcription is essential — it enables our coaching system to deliver instant feedback and correction right after each mock call. This real-time loop helps reps improve faster, and we’re thankful to the Deepgram team for enabling it.

used Deepgram to build InterviewBee AI

•3 reviews

Deepgram outperforms Google Speech-to-Text and AWS Transcribe for our interview transcription needs with higher accuracy for diverse accents and technical terminology (95%+ vs 85-90%). Unlike Whisper, Deepgram processes speech in real-time with minimal latency (200-300ms), which is crucial during interviews. Assembly AI was competitive but didn't match Deepgram's performance with background noise in typical video call environments.

used Deepgram to build Layercode CLI

•3 reviews

Nailing accurate speech-to-text transcription is the first — crucial — step to any agent powered by a voice pipeline. We've tested a lot of STT models and found Deepgram to consistently beat the alternatives when it comes to speed and accuracy. We're excited to be able to offer their speech-to-text transcription to all users building voice agents with Layercode.
