What is TTS?

A text-to-speech player using the browser's native speechSynthesis: choose a system voice and rate, then hear your text read aloud.

How it works

A SpeechSynthesisUtterance is created for your text, assigned the selected voice and rate, and queued on speechSynthesis — all local to the browser.

Frequently asked questions

Why does the voice list vary?

Voices come from your operating system and browser — different devices have different installed voices, which is why the list changes per machine.
