Visit Hume AI (Octave) →Emotionally expressive speech that understands context
Who it's for
Developers and product teams building emotionally expressive voice agents, companions, or interactive applications who want natural-language emotional control without SSML and at roughly half ElevenLabs' pricing.
Who it's not for
Non-technical users wanting a simple point-and-click studio, or teams needing broad language coverage beyond English today, should consider Murf or ElevenLabs instead.

Pros
- Octave 2 is an LLM-native speech model that infers emotional context automatically — no SSML tags needed to whisper, sound sarcastic, etc.
- Fast generation (as low as ~100-200ms), suitable for real-time conversational use
- Preferred over rivals in blind studies for audio quality (71.6%) and naturalness (51.7%) in Hume's own testing
- Roughly half the price of ElevenLabs for comparable emotional TTS
Cons
- Developer/API-oriented platform with a learning curve for non-technical users
- Best results are in English; other languages (11 currently, expanding) lag behind
- Not ideal if you just need basic voice generation without emotional/expressive control
