- Increase sensitivity from 0.5 to 1.0 for better vowel/consonant detection
- Reduce min_duration from 0.1s to 0.05s for faster response to mouth movements
- Lower confidence_threshold from 0.3 to 0.02 for more permissive detection
- Boost viseme_sensitivity from 1.0 to 2.0 for enhanced geometric analysis
- Disable viseme_smoothing (0.3→0.0) for immediate response without temporal delay
These optimizations improve detection accuracy and responsiveness based on testing feedback.
