About AI Lipsync & AI Dubbing APIs

AI LIPSYNC + AI DUBBING

One unified Pixazo API for AI lipsync, AI dubbing, and AI talking avatars. Re-voice video into any language, generate presenters from a script, or sync any audio to any face — through a single API key, with Sync, Heygen Video Agent, OmniHuman, Kling, Pixverse, and Veed all behind one endpoint.

How AI Lipsync & AI Dubbing Work

STEP 01

Upload

Send a face video + new audio (or a reference image + script for fully synthetic avatars).

STEP 02

Translate

Optional: pipe through Pixazo TTS or voice-clone to generate audio in any language first.

STEP 03

Sync

The model re-drives the mouth region frame-by-frame to match the new waveform.

STEP 04

Deliver

Render-ready MP4 with the new audio muxed in — eyes, blinks, and head motion preserved.

Frequently Asked Questions

What is the difference between AI lipsync and AI dubbing?
AI lipsync syncs a face video to a new audio track so lip movements match the speech. AI dubbing combines lipsync with voice translation/synthesis so a video can be re-voiced into any language while the mouth still matches the new words. Pixazo's AI Lipsync API covers both — bring your own translated audio, or pair the API with a TTS / voice clone model on the same key.
Which AI lipsync API is best for film and TV dubbing?
For high-fidelity film and TV dubbing where the original speaker is on camera, Sync (Sync.so) and OmniHuman (ByteDance) typically produce the most cinematic results. Heygen Video Agent is best when you need a fully synthetic AI presenter rather than re-voicing real footage.
How does the AI multilingual dubbing API handle different languages?
The lipsync models are language-agnostic — they react to the audio waveform, not the script. Generate or upload audio in any language (English, Spanish, Hindi, Mandarin, Arabic, French, German, Japanese, Korean, Portuguese, and dozens more) and the API will resync the speaker's lips to the new track.
Can I use AI lipsync for talking avatars and virtual presenters?
Yes. Heygen Video Agent and OmniHuman generate full talking avatar videos from a single reference image plus an audio file or script. Kling Lipsync and Pixverse Lipsync are best when you already have video footage of a face and need to swap the audio.
What input formats does the Lipsync API accept?
Standard MP4/MOV/WebM for video, MP3/WAV/M4A for audio, and JPG/PNG for reference avatar images. Per-model limits are listed on each model's /models page. The response is render-ready MP4 with the new audio muxed in.
How much does the AI lipsync and AI dubbing API cost?
Pricing is per second of output video and varies by model. There are no monthly minimums and no separate account for each provider. The cheapest tier today is Pixverse Lipsync; the most cinematic is Sync v3.
Does the API preserve original facial expressions during dubbing?
Sync v3 and OmniHuman are explicitly tuned to preserve the speaker's original eye contact, blinks, brow movement, and head sway while only re-driving the mouth region. Kling and Pixverse take a slightly more aggressive approach.
How fast is AI lipsync generation?
Most short clips (10-30 seconds) return in 30 seconds to 3 minutes depending on the model and resolution. Pixverse Lipsync and Kling Lipsync are the fastest. Sync v3 and OmniHuman are slower but produce broadcast-quality output.

One API key. Six models. Lip-sync, dub, and animate — from any voice to any face, in any language.
