Deepgram

Deepgram is an enterprise voice AI platform that provides speech-to-text, text-to-speech, and voice agent APIs powered by advanced AI models. The platform offers real-time and batch transcription through its Nova model family, natural-sounding speech synthesis through its Aura model family, and an end-to-end Voice Agent API that combines STT, LLM orchestration, and TTS into a single real-time interface.

Deepgram publishes 12 APIs on the APIs.io network, including Voice Agent API, Balances API, Invitations API, and 9 more. Tagged areas include Artificial Intelligence, Speech-To-Text, Text-To-Speech, Transcription, and Voice AI.

The Deepgram catalog on APIs.io includes 3 event-driven AsyncAPI specifications, 1 JSON-LD context, and 5 Spectral governance rulesets.

Deepgram’s developer surface includes authentication, documentation, pricing, changelog, and 25 more developer resources.
