Open **AI Studio → Imagine → Lip sync** to create a speaking portrait. This is different from general video generation: the audio supplies the performance that the face follows.

## Prepare the portrait and voice

<Steps>
  <Step title="Choose the portrait">Supply a clear image of the intended face. Use a portrait you own or have permission to animate.</Step>
  <Step title="Supply the speech">Add an audio reference, or use the integrated Text to Speech option to create narration from your script.</Step>
  <Step title="Review settings and credits">Choose the supported model/settings and check the estimate before generating.</Step>
  <Step title="Inspect the result">Play the finished clip. Check timing, pronunciation and facial movement before sharing it.</Step>
</Steps>

## Text to Speech inside Lip sync

The narration option uses the same Speech workspace as the main **Speech** tab. Choose a voice, model and delivery settings, then use the generated audio for your portrait. See [Speech and voices](/studio/speech) for voice filters, expressive delivery and output settings.

## Get a cleaner result

* Start with a clear face and an uncluttered composition.
* Use clean audio with one intended speaker.
* Correct the script and pronunciation before generating the animation.
* Inspect the full clip; realistic results still need human review.

<AccordionGroup>
  <Accordion title="Can I use audio I already recorded?">Yes, supply it as the audio reference and pair it with the portrait.</Accordion>
  <Accordion title="Do I need to generate a video first?">No. Lip sync starts from a portrait and speech; general scene clips belong in [Video](/studio/video).</Accordion>
  <Accordion title="Is this covered by Speech's ZDR badge?">Speech generation and portrait animation are separate operations. Do not extend the Speech badge to Imagine's Non-ZDR animation service.</Accordion>
