What is Deepgram?

Deepgram is a developer platform for speech AI: its Nova speech-to-text models transcribe live and recorded audio with high accuracy and low latency, and the platform adds text-to-speech, diarization, redaction and speech-understanding features around it. Developers integrate through a clean API and SDKs, paying for what they process rather than buying seats.

Call centres, meeting tools and voice agents run on Deepgram because it holds up on accents, noisy audio and domain vocabulary better than most rivals. It is not a consumer product — there is nothing to click if you just want a transcript — and costs need watching on always-on streaming. For builders, though, it is a default shortlist choice for speech infrastructure.
