Text to Speech
Free online text-to-speech tool: natural main engine (CosyVoice 3) + emotional voice engine (IndexTTS-2), supports multiple voices, adjustable speed/pitch/volume, multilingual, emotional styles, voice cloning, and multi-speaker dialogue.

Style/emotion works best with “Voice clone” and custom reference voices; preset named voices mostly keep their own character.
