  • The tool is suitable for proofreading written work by listening to how sentences sound spoken aloud.

Common problems

No voices appear in the dropdown menu

Some browsers load voices asynchronously; wait a few moments or refresh the page to allow the voiceschanged event to fire.

Speech stops abruptly on long texts

Certain browsers have a known 15-second speech synthesis boundary; break long articles into smaller paragraphs for continuous playback.

Frequently Asked Questions (FAQ)

Does this text-to-speech tool send my text to external cloud APIs?

No. The tool uses the W3C Web Speech API, which communicates directly with speech engines installed on your operating system.

Can I download the synthesized speech as an MP3?

The Web Speech API renders audio directly to hardware output streams without exposing raw sample buffers for direct file download.

Which languages are supported?

Any language with an installed voice pack on your operating system will appear in the selection menu.

Files never leave your device; calculations and transformations happen locally.
