Text to Speech

How to use the text to speech tool

1. Pick a voice — 9 options across US and UK English, male and female.
2. Choose a speed: 0.75× for slow and clear, 1× normal, 1.25× or 1.5× for faster listening.
3. Paste or type any text into the box — articles, emails, scripts, docs. No character limit.
4. Click Generate speech. Audio starts streaming sentence by sentence — no wait for the full text.
5. Follow the read-along pane as each sentence is highlighted while it plays.
6. Click Download WAV once generation finishes to save the full audio file.

Why use this tool?

• Streaming playback — audio starts immediately for the first sentence while the rest is still generating, so you never wait for long texts.
• Read-along highlighting — each sentence is highlighted as it plays, making it easy to follow along with articles or scripts.
• No character limit — paste an entire book chapter, a long report, or anything else. The model handles it sentence by sentence.
• 9 natural voices — US and UK English, male and female, with distinct personalities from warm and expressive to professional and neutral.
• 100% private — the Kokoro AI model runs entirely in your browser. Your text never leaves your device.
• WAV download — save the full audio file for offline listening, podcast production, or accessibility tooling.
