Text-to-Speech

Problem

Unattended displays and presentations sometimes need spoken narration to accompany visual content.

Solution

Text-to-Speech reads scripts aloud using macOS system voices. Audio ducking automatically lowers video volume during narration. Users write a script with timestamps or scene triggers, and FlexGrid speaks each segment at the appropriate moment.

UI Flow

  1. Open Settings > Audio > Text-to-Speech.
  2. Write or paste a narration script.
  3. Assign segments to scenes or timestamps.
  4. Select a system voice and speaking rate.
  5. Enable audio ducking to lower grid audio during speech.

Tier Availability

Pro only.

Known Limitations

  • Uses macOS AVSpeechSynthesizer; voice quality depends on installed system voices.
  • No SSML support; emphasis and pauses are controlled by punctuation only.
