Hume's Octave, an LLM developed by Hume AI, claims to outperform ElevenLabs in capturing human-like emotions in AI voices.
Octave is an Omni-Capable Text and Voice Engine specifically designed for text-to-speech tasks.
Hume organized a blind comparison study with 180 human raters, where Octave's outputs were favored over ElevenLabs in several aspects like audio quality, naturalness, and prompt matching.
Octave's voice cloning feature will soon allow users to clone a voice from as little as five seconds of audio.
