Analysis of Emotion Control Techniques
Dia enables emotion regulation through three key types of technology:
- Audio cue guide: After uploading the reference audio, the model extracts its rhythmic features (e.g., speech rate, pitch) and migrates them to the newly generated speech.
- Parametric control: The CFG ratio (default 3.0) and temperature parameter (default 1.3) are linked to regulate the deterministic and emotional fluctuation amplitude of speech.
- Script Markup System: Labeling the emotion state directly in the text (e.g., "(excited)"), the model calls the corresponding latent space representation.
Tests show that when used with fixed seeds, the model maintains sentiment consistency across utterances for the same character, which makes it particularly suitable for role-playing type application scenarios.
