Free open-source AI voice generator that turns any text into natural speech
Generates speech from the openly licensed Kokoro TTS model, which produces smoother, more human-like intonation than classic concatenative engines.
You can generate audio immediately in the browser without creating an account, entering a credit card, or working through a credit balance.
The interface can be run on your own machine or server, letting you keep text and audio entirely inside your own environment.
Offers a range of voice presets so you can match a narrator tone to narration, dialogue, tutorials, or accessibility use.
Text to speech and voice AI across every device
Listen to books, PDFs, documents and web pages read aloud in a large library of lifelike AI voices.
Dictate instead of typing in almost any app, across Google Docs, Gmail, Slack, Outlook and more.
Turn documents or a short prompt into an AI podcast, and get instant summaries of what you are reading.
Use the web app, Chrome and Edge extensions, and native iOS, Android, Mac and Windows apps.
