Why the voices differ on every device
This tool does not have voices of its own. It asks your browser to speak, and the browser uses the voices your operating system and browser provide. So the same text sounds different on a phone, a Mac, a Windows laptop or a Chromebook, and the list of languages changes too.
Some voices are installed on the device and work offline. Others, often marked as online or network voices, are streamed by the browser maker and need a connection. If a language you need is missing, add a voice for it in your device’s language or speech settings and reload this page.
- On iPhone and iPad, more voices can be downloaded in the accessibility settings under spoken content.
- On Android, the voices come from the text to speech engine chosen in the device settings.
- On Windows and macOS, extra voices are added in the system language or speech settings.
When you need an AI voice instead
Browser voices are good for listening: proofreading a script, hearing an article while you do something else, or checking how a line sounds. They are not made for publishing. A browser cannot save what it speaks as an audio file, and the voice you hear depends on the listener’s device, not yours.
For a voiceover, a video or anything you share, you need a voice that renders to a file and sounds the same everywhere. That is what an AI voice generator does, and with voice cloning it can be your own voice reading the script.
