Text to Speech Reader

No — it uses the Web Speech API's built-in SpeechSynthesis interface, which is implemented natively by your browser/operating system. Your text is processed entirely on your device and never sent anywhere.

Available voices come directly from your browser and operating system's installed speech synthesis voices, which vary by platform (Windows, macOS, Chrome OS) and can take a moment to load asynchronously — the list automatically repopulates once your browser reports the voices are ready.

Rate controls how fast the speech plays (1.0 is normal speed, higher is faster), and Pitch controls the relative pitch of the voice (1.0 is the voice's default pitch) — both map directly to the standard SpeechSynthesisUtterance.rate and .pitch properties.

Some browsers require a user interaction (like a click) before allowing audio playback, and this tool's Play button already satisfies that — if it still doesn't work, check that the "Unsupported" warning isn't showing, since SpeechSynthesis support does vary by browser.

Yes — the Pause and Resume buttons call the browser's native speechSynthesis.pause() and .resume() methods, which suspend and continue the same utterance rather than restarting it from the beginning.
