The Advantage of IndexTTS2 Emotion Control
This tool is highly effective because it can shift the output emotion (from happy to sad) while perfectly preserving the unique character and tone of the original reference voice.
Tone Experimentation Tips
Most TTS generators only produce flat, neutral tones. Try using the emotion sliders at varying levels (rather than just 0 or 1) to achieve more natural and realistic vocal expressions.

Step by Step
How to Control AI Voice Emotions in IndexTTS2
- Upload a reference audio file (e.g., American female voice) to the IndexTTS2 platform.
- Click the 'Play' button on the original clip to listen to the quality and tone of the reference voice.
- Enter the text you want to generate into the 'Transcript' field.
- Locate the 'Emotion Sliders' section, which features options such as Happy, Sad, and Angry.
- Drag the 'Happy' slider to the right until it reaches '1' for a very joyful tone.
- Click the 'Synthesize' button to generate the voice based on these emotion settings.
- To change the emotion to sad, drag the 'Sad' slider to '1' (ensure other emotion sliders are adjusted accordingly).
- Click the 'Synthesize' button again to produce a new voice output with a sadder tone.
