Single API for low-latency voice agents bundling Deepgram ASR + LLM + TTS.
Best for developers wanting one provider for ASR, LLM routing, and TTS in a voice agent. Pricing: see vendor pricing.
What it is
Deepgram released its Voice Agent API as a turnkey alternative to OpenAI Realtime, pairing its Nova ASR with an Aura TTS voice and an LLM proxy. The API exposes one streaming WebSocket for the full conversational loop. Buyers pick Deepgram Voice Agent when they already trust Deepgram ASR and want simpler integration than stitching three providers.
Watch out for: Locked into Deepgram's hosted stack; less flexibility per layer.
