# Deep Acting: Real-Time Audio-Driven Facial Animation
Creating expressive digital actors has historically required motion capture suits, facial markers, and hours of cleanup. With Higsfield's neural lip-sync engine, voice recordings instantly drive realistic muscular contractions around the mouth, eyelids, and jaw.

1. Beyond Mouth Flaps: Micro-Expressions
Traditional automated lip-sync only maps basic visemes (shapes for 'A', 'E', 'O', 'M'). However, genuine human speech activates:
- Micro-squints during accented syllables.
- Breathing cycles between sentences.
- Natural head drift and vocal cord tension.
Higsfield's multi-task acoustic encoder reads voice intensity and pitch inflection, applying corresponding natural head tilts and eyebrow movements automatically.

2. Multi-Language Adaptability
Whether your voice track is English, Spanish, Japanese, or French, our model understands phonetic variations and adapts mouth geometry to native speaker standards.
