# Simultaneous Speech

> Dub multiple speakers talking at the same time within a single segment.

Simultaneous Speech lets you assign multiple speakers to a single segment so their voices are merged into one audio clip when speech is generated. This is useful for moments where multiple people speak at the same time, such as when a group says something in unison.

## Enable Simultaneous Speech

<Steps>
  <Step title="Open the Change Speaker dropdown">
    Click the speaker tag on a segment to open the **Change Speaker** dropdown.
  </Step>

  <Step title="Click the Simultaneous Speech icon">
    Click the **Select Multiple Speakers for Simultaneous Speech** icon in the top-right corner of the dropdown. A **Multi-Speaker Segment** dialog will appear.
