What is AI lip sync?

AI lip sync animates a face to speak any audio track by generating matching mouth shapes, expressions and head motion.

Modern talking-head models go far beyond mouth flaps: they synthesize blinks, eyebrow movement and subtle head sway that track the audio's rhythm and emotion. One clear portrait plus one audio file produces broadcast-ready talking video — the backbone of AI avatars, virtual presenters and multilingual content.

Common questions, straight answers

Can I lip sync a generated AI face?

Yes — generate a face with the Face Generator, then feed it to Lip Sync with your audio. This is the standard AI influencer talking-video workflow on Pixogen.

What audio quality do I need?

Clean speech without heavy background noise syncs best. 44.1kHz MP3 or WAV recordings are ideal; TTS output works excellently.
