How does text to speech work?

This tool uses the browser-native SpeechSynthesis Web API. Your operating system provides the available voices — typically dozens in different languages and accents. The text is sent directly to the OS speech engine and never leaves your device. Adjust the rate (0.5x-2x), pitch (0-2), and volume (0-1) to fine-tune the output.

Browser support

  • Chrome / Edge — full support, dozens of voices including Google online voices.
  • Safari — full support, uses macOS / iOS system voices.
  • Firefox — limited support, may need OS-level voices installed.

Common uses

  • Accessibility — listen to written content while doing other tasks.
  • Proofreading — catch typos and awkward phrasing by ear.
  • Language learning — hear correct pronunciation in target languages.
  • Content creation — preview voiceover scripts before recording.

Privacy

All speech synthesis runs locally via your browser/OS. No text or audio is sent to any server.
