Frequently Asked Questions
Is my text sent to a server?
No. This tool uses the Web Speech API built into your browser. Your text is processed locally on your device and is never sent to any server, API, or third-party service.
Why do I see different voices on different devices?
The available voices depend on your operating system and browser. macOS, Windows, iOS, and Android each include different built-in voices. Chrome and Edge may also offer additional online voices.
Can I adjust the speed and pitch?
Yes. The Speed slider lets you set the rate from 0.5x (half speed) to 2x (double speed). The Pitch slider lets you adjust pitch from 0.5 (lower) to 2.0 (higher). Changes take effect on the next playback.
Does word highlighting work in all browsers?
Word highlighting relies on the SpeechSynthesis boundary event, which is supported in most modern browsers including Chrome, Edge, and Safari. Some browsers may have limited support for boundary events.
Is there a text length limit?
There is no hard limit imposed by this tool. However, some browsers may pause or split long texts internally. For best results with very long texts, consider breaking them into sections.
