Reviewer scorecard
“The API is clean and the latency is impressive — sub-300ms for real-time transcription. Building voice features into apps has never been easier or cheaper.”
“Accuracy is competitive with Google Cloud Speech and AWS Transcribe at a lower price point. The developer experience is significantly better than both.”
“The API design is thoughtful. Integrates well with existing stacks.”
“Voice interfaces are the next platform shift. Deepgram is building the pipes. Every app will have voice input within 3 years — Deepgram will power many of them.”
“Fast, reliable, and the docs are actually good. Ship.”
