How do you do text-to-speech in iMovie?

Most people are searching for ways to do text-to-speech in iMovie. So is there text to speech feature in iMovie? Unfortunately, iMovie does not have the built-in text-to-speech function for users to generate natural-sounding voiceover from text. Instead, it enables you to record self-narration voice to make your video more engaging or add text overlays to your videos without the text being read aloud by using title templates and captions within iMovie.

While iMovie does not have a built-in TTS tool, you can still apply two workarounds for getting AI voiceover into iMovie:

  • 1)Use External AI Voice Generator: Firstly, you can do text-to-speech on third-party platforms, download the generated high-quality, natural-sounding AI voiceovers and import the downloaded audio file directly onto the timeline under your video clips in iMovie.
  • 2)Free macOS System Audio Trick: If you are on a Mac and do not want to use third-party apps, you can generate speech using Terminal app. Open Terminal on your Mac and type: say -o voiceover.aiff "Type the text you want spoken here" This creates an audio file named voiceover.aiff in your user folder, which you can drag directly into iMovie.
