The legacy standard for lightweight 3D character animation and community-driven motion synthesis.

The industry standard for speech-driven facial animation and lip-sync performance.

JALI (Joint Acoustic-to-Linguistic Inference) is a sophisticated AI-driven facial animation suite that automates the process of creating high-fidelity character performances from audio and text. Originally developed through research at the University of Toronto and showcased globally via CD Projekt Red's Cyberpunk 2077, JALI operates on a rule-based acoustic model rather than simple machine learning playback. It calculates phonemes, co-articulation, and anatomical constraints of the human face to produce believable speech-driven movement. By 2026, JALI's architecture has transitioned into a hybrid cloud-and-local model, offering deep integration with Maya and Unreal Engine 5. It excels in the 'uncanny valley' problem by managing secondary motions like micro-expressions, gaze direction, and blinking based on the emotional cadence of the input audio. Its market position is centered on AAA game development pipelines and high-end cinematic production, where the volume of dialogue renders manual animation impossible but quality cannot be compromised. The technical framework supports massive localization projects, allowing developers to generate lip-sync for dozens of languages using the same underlying phonetic engine.

Explore all tools that specialize in automated lip-sync. This domain focus ensures JALI Research delivers optimized results for this specific requirement.
Models the physical limitations and overlap of mouth shapes based on preceding and succeeding sounds.
Uses the International Phonetic Alphabet to generate accurate sync for over 30 languages.
Runtime engine for real-time lip-sync in games based on dynamic voice-over or AI dialogue.
Analyzes audio peaks and pauses to trigger realistic eye darting and blinking.
Visual interface to manually adjust the timing of specific phonemes against the waveform.
Allows layering of 'angry', 'sad', or 'happy' facial states over the lip-sync data.
Scriptable interface to process thousands of audio files through the JALI pipeline without manual intervention.
Install JALI LipSync plugin for Autodesk Maya.
Initialize character rig using JALI's specific naming convention or mapping tool.
Import high-quality WAV audio file (mono, 48kHz recommended).
Provide corresponding text script for increased phonetic accuracy.
Run the Acoustic-to-Phonetic inference engine.
Review generated phonemes in the JALI Timeline editor.
Adjust emotional intensity sliders for the 'Performance' layer.
