Text to Speech¶

Create a speech item¶

Open the add menu on an audio track.
Choose Text to Speech.
Select the new item and enter its text in the inspector.
Choose a model and set the controls it shows.
Generate the speech.

Generate speech for captions¶

Select caption clips and choose Generate Speech from the timeline context menu. The same action on a caption track reads every caption that has text.

Pick a model that supports caption timing. Each caption is spoken at its current duration. The audio lands on a track where it does not overlap existing clips.
