What happened
Deepgram extended the turn-aware Flux design from speech recognition to speech synthesis. That gives it a full in-house agent stack (Flux STT + LLM + Flux TTS) behind its Voice Agent API.
Why it matters
Voice-agent vendors are building TTS around dialogue state (turns, interruptions, what was actually heard) rather than isolated sentences. Deepgram’s $100M ARR also shows the market for speech APIs is growing.
