Hume Octave TTS

What we know about Hume Octave TTS

Hume Octave TTS is a text-to-speech apis platform: expressiveness-first TTS (Octave understands the meaning of the text it speaks); subscription plans gate commercial use, with Octave 2 (preview) adding ~100ms latency and 11 languages for realtime use. This profile tracks what we have verified about Hume Octave TTS, each fact linked to a primary source and dated.

On pricing, Hume Octave TTS starts at $3 per month for its entry tier. That is the sticker rate: real production cost usually runs higher once you add a language model, a voice provider, and telephony minutes. Every Hume Octave TTS comparison on the site works from that all-in figure rather than the headline number, because the headline number is rarely what the invoice says.

On capabilities, Hume Octave TTS covers streaming audio output, realtime websocket api, instant voice cloning, emotion / style controls, and word-level timestamps, and does not offer commercial use on free tier. Each of those is verified against Hume Octave TTS's own docs or dashboard, not marketing copy.
