Deepgram Aura-2
purpose-built for english voice agents
built for conversational agents: simple per-character pricing, low-latency streaming, generous free credit, and it pairs with deepgram stt for a full agent loop. narrower on languages, not a cloning tool.
deepgram's aura-2 is a tts model aimed squarely at english voice agents — a large voice set, low-latency streaming, and clean rest/websocket apis, with $200 in free credit for new accounts. its real advantage is pairing with deepgram's speech-to-text so your whole agent loop (listen and speak) comes from one vendor with one integration.
it's english-focused with narrower language coverage than google or azure, its sub-250ms latency claim is unbenchmarked, and it isn't a cloning or narration tool. for english ivr and voice agents where stt+tts unity matters, it's a strong, simple choice.
