About the neural text-to-speech tool
A free text-to-speech tool that generates natural-sounding speech entirely in your browser with the Kokoro neural voice model. Use it for narration drafts, voiceovers for video, language learning, accessibility, or previewing writing aloud — with no account, no API keys, and no per-word pricing.
How it works
Kokoro is a compact, high-quality neural TTS model running via Transformers.js, with WebGPU acceleration when the browser supports it. Two engines ship with the tool: 28 American and British English voices (graded A–F for naturalness) and 100 Mandarin voices, including a v1.1-zh build that reads mixed Chinese–English text naturally. Text is synthesized locally into audio you can play instantly and export as WAV. Voices and model weights download once and are then cached, after which synthesis works offline.
Limits & requirements
First run downloads model and voice data. Each generation accepts up to 500 characters, so long passages are best processed section by section; synthesis itself returns in seconds once the models are cached. Quality is strongest on English and Mandarin — the two engines shipped here.
Privacy
Cloud TTS services receive every word you type — including, routinely, confidential draft content. Here your text never leaves the browser. Scripts, notes, and documents you read aloud remain private by construction.
