What You Can Create with AI Lip Sync

Create talking photos, resynced speaker clips, localized messages, and repeatable presenter content in one workflow.

Talking photo

Turn a portrait into a speaker

Use a clear portrait with recorded or generated speech. Keep the face, words, delivery controls, and 720p or 1080p output in one workflow.

Existing video

Resync an existing speaker video

Pair a stable speaker clip with a separate audio file. A visible mouth, clean speech, and limited cuts give PixVerse Lip Sync a clearer timing target.

Generated voice

Localize one presenter across languages

Enter a script, then choose a supported language, voice, and speaking style for explainers, lessons, onboarding, and recurring updates.

Delivery control

Control the look and delivery

Keep speech source, language, speaking style, visual direction, negative guidance, and resolution connected to the same face and audio.

Campaign variants

Update messages without reshooting

Reuse one presenter for product updates, lessons, and internal messages. Review timing and identity before publishing.

How to Use AI Lip Sync Video Generator

Start with the source you already have, keep the first test short, and review the complete speaking performance.

Choose portrait or video lip sync

Select P Video Avatar for one portrait plus speech, or PixVerse Lip Sync for an existing speaker video plus separate audio. The form updates to show only the active model requirements.

Add clear speech

Upload a clean recording or, in portrait mode, enter a script and select a supported language, voice, and speaking style. Match the delivery to the visible expression for a more natural result.

Generate and inspect

Check the credit estimate, create the result, then watch every line for mouth timing, facial consistency, unwanted looping, and audio alignment before you publish.

AI Lip Sync Video Generator Use Cases

Use synchronized speaking video when the message changes more often than the presenter setup.

Localized creator and social videos

Adapt one presenter into short explainers, hooks, announcements, and language variants without recording the same visual setup for every speech track.

Product and brand messages

Create spokesperson drafts, product introductions, founder updates, campaign variants, and ecommerce messages from a consistent presenter and voice.

Lessons, onboarding, and training

Prepare lesson intros, onboarding clips, internal summaries, and recurring training messages with one recognizable presenter and reviewable speech timing.

Who AI Lip Sync Video Generator Is For

The workflow fits teams that need faster talking-video variants from a consistent presenter, voice, and message.

Creators

Make repeatable presenter clips, character tests, social hooks, and multilingual versions from the same source assets.

Marketing teams

Draft product messages, campaign updates, paid-social variations, and spokesperson content without reshooting each line.

Localization teams

Test translations and supported generated voices while comparing delivery, tone, and cultural fit before release.

Why Choose Our AI Lip Sync Video Generator

Flexible speech sources

Reuse existing recordings or create supported generated speech from a script without moving to a separate talking-video tool.

AI Lip Sync Video Generator FAQ

What is an AI Lip Sync Video Generator?

An AI Lip Sync Video Generator makes visible mouth and facial movement follow a speech track. This page supports a portrait-to-talking-video workflow with uploaded or generated speech and a separate workflow for synchronizing an existing speaker video to new audio.

Can I make a talking photo from one image?

Yes. Select P Video Avatar, upload a clear JPG, PNG, or WebP portrait, and then upload MP3, WAV, or M4A speech or enter a script. The current form shows supported voice, language, direction, and resolution choices.

Can I lip sync an existing video to different audio?

Yes. PixVerse Lip Sync accepts an MP4, MOV, or WebM source clip up to 100MB and separate MP3, WAV, M4A, AAC, or OGG speech up to 50MB. Use one visible speaker and note that a short video may loop when the audio is longer.

Which generated voice languages are available?

The current avatar workflow includes English US and UK, Spanish, French, German, Italian, Portuguese Brazil, Japanese, Korean, and Hindi choices. Check the live selector because available voices and languages can change.

How can I get more natural lip sync?

Use a sharp, mostly front-facing face, stable framing, clean speech without overlapping voices, and a delivery that fits the visible expression. Review the entire result because fast syllables, teeth, jaw movement, identity, and extreme turns can still vary.

Does AI lip sync preserve a face perfectly?

No generative workflow guarantees perfect identity or timing in every frame. Test a short segment, inspect the whole result, and regenerate with a simpler source when the mouth, teeth, jawline, expression, or face drifts.

Can I use any face or voice?

No. Use only faces, recordings, and voice material you own or are authorized to process. Do not impersonate people or publish deceptive media, and disclose synthetic or altered content when the context or applicable rules require it.

Choose a clear face, add speech, and create a synchronized video ready for preview and download.
