# Dialogue and Lipsync

> Add voice performances that stay in sync with your characters

The Dialogue and Lipsync tab allows you to generate dialogue audio from text and automatically sync it to your character's lip movements. This two-step workflow lets you create natural-sounding voice performances and apply them to your rendered shots.

## Workflow

### Step 1: Generate Dialogue Audio

1. Enter the dialogue text you want the character to speak
2. Select from the list which character is speaking
3. Click **Generate Dialogue** — Automat will create audio using text-to-speech models
4. Listen to the generated audio clip
5. Generate multiple times — Each generation will have a different performance and delivery
6. Cycle through generations and click **Play** to listen and compare takes
7. Once you're satisfied with a take, select it to use for lipsync

<Note>
  You can make as many dialogue generations as you like. Each generation will have a slightly different performance, allowing you to find the perfect delivery for your scene. See the [Text-to-Audio models guide](/models/text-to-audio) for available voice models.
</Note>

### Step 2: Apply Lipsync to Video

1. With your preferred dialogue audio selected, click **Generate Lipsync**
2. This will apply the selected dialogue to the active video generation
3. Wait for the lipsync generation to complete (typically 30-90 seconds)
4. Watch the new video in the left-hand side viewer
5. Review the synced result — If the sync isn't perfect, adjust settings and regenerate

<Note>
  Lipsync generation applies the dialogue audio to your rendered video, automatically matching lip movements, facial expressions, and subtle head motions to the voice performance. See the [Audio-to-Video models guide](/models/audio-to-video) for details on available lipsync models.
</Note>

## Advanced Options

### Model Selection

Enable **"Show Models"** to select different dialogue and lipsync models. This allows you to:

* Choose specific voice models for different characters
* Select lipsync models based on quality vs. speed preferences
* Experiment with different model combinations for best results

<Note>
  **Recommended models** provide the best balance of quality and speed. **Supported models** may have different characteristics—experiment to find what works best for your specific shot.
</Note>

## Tips for Best Results

1. **Generate Multiple Takes** — Create several dialogue generations to compare different performances
2. **Match Character Voices** — Use consistent voice profiles for each character across your project
3. **Check Sync Accuracy** — Review the final video to ensure lip movements match the dialogue timing
4. **Iterate if Needed** — Regenerate lipsync with different settings or models if the sync isn't perfect
