What it does

Deepgram is an enterprise voice AI platform that unifies speech-to-text, text-to-speech and voice-agent orchestration behind a single API. Its model families include Nova and Flux for conversation-aware speech recognition, expressive text-to-speech models, and a Voice Agent API that combines STT, TTS and business logic, running in real time or batch, in the cloud or self-hosted.

How to use: 1. Sign up for a free Deepgram Console account with trial credits. 2. Try models in the API Playground. 3. Integrate the speech-to-text, text-to-speech or Voice Agent API into your app using the docs and SDKs. 4. Scale on pay-as-you-go pricing or move to enterprise or self-hosted deployment.
