Generate natural speech with 28 American and British AI voices, adjustable speed, private browser processing, and MP3 or WAV downloads.
The quantized Kokoro model downloads once and is cached by your browser. Your text and generated audio stay on this device.
AI text to speech converts written words into spoken audio with a neural voice model. Unlike basic browser narration, it models rhythm, pronunciation, and vocal tone to create more natural speech.
This online text to speech generator runs the quantized Kokoro 82M model in your browser. It currently provides 28 English voices across American and British accents, adjustable speaking speed, instant playback, and downloadable MP3 or WAV audio.
Choose from American and British female and male voices for narration, study audio, short videos, and spoken content.
Your text is processed on this device after the voice model loads. The script and generated audio are not sent to our server.
Set the voice from 0.5x for careful listening to 2.0x for faster narration without editing the source text.
Export a compact MP3 for publishing and sharing or a WAV file for editing and lossless production workflows.
The voice library is organized by accent and voice style so you can compare a smaller, relevant set before generating a complete script.
Compare 11 US English voices for narration, tutorials, study audio, product videos, and spoken articles.
Choose from 9 US English voices with different pacing and vocal character for explainers, podcasts, and presentations.
Preview 4 UK English voices when a British accent better matches the script, audience, or listening material.
Use 4 UK English voices for narration, educational audio, dialogue drafts, and accessibility-focused listening.
Create downloadable speech in three steps. The first generation downloads the AI model; later visits can reuse the browser cache.
Type or paste a script, article, narration, or study notes, or import a plain .txt file from your device.
Select one of 28 American or British voices, play a short voice preview, and set the speaking speed from 0.5x to 2.0x.
Choose MP3 or WAV, generate the speech locally, listen to the complete result, and download the finished file.
A downloadable AI voice can turn text-first work into audio without a recording session.
Create narration for YouTube videos, product demos, tutorials, Shorts, Reels, and presentation videos.
Convert notes and reading material into audio for review, pronunciation practice, or listening while away from the screen.
Listen to an article, email, or script to catch awkward phrasing, repeated words, and missing transitions.
Produce drafts, intros, announcements, or spoken versions of text for audiences who prefer audio.
Small changes to punctuation and sentence structure can make generated speech easier to understand.
Use short sentences, normal punctuation, and paragraph breaks so the voice has clear places to pause.
A voice that suits a tutorial may not suit a dramatic script. Compare several voices before generating long text.
Rewrite unusual abbreviations, symbols, dates, or technical terms when pronunciation matters.
Choose WAV when you plan to cut, mix, normalize, or process the generated speech in another audio tool.
Text to speech tools differ in voice quality, privacy, setup, and export support.

Desktop Chrome, Edge, or Firefox is recommended. Safari does not currently run this local AI model reliably.
Yes. You can enter text, choose a voice, adjust speed, generate speech, preview it, and download MP3 or WAV without creating an account.
No. After the Kokoro model downloads, speech generation runs locally in the browser. Your text and generated audio stay on this device.
The quantized browser model is roughly 80 to 100 MB. A typical desktop connection may load it in 15 to 60 seconds, while slower connections can take longer. The browser can cache it for later visits.
Generation time depends on the device and script length. On a modern desktop, one minute of speech often takes about 12 to 50 seconds to generate, with a few additional seconds for MP3 encoding.
The current tool includes 28 English voices grouped into American female, American male, British female, and British male voices.
Yes. Choose MP3 for a smaller file that is easy to publish and share, or WAV for lossless editing and production.
The page processes long text in smaller sections rather than applying a fixed short character limit. Very long scripts still require more memory and generation time, so keep the tab open until processing finishes.
The local Kokoro model depends on browser features that are currently more reliable in desktop Chrome, Edge, and Firefox. Use one of those browsers for generation and downloads.
Check the license terms for the Kokoro model and any text you provide before commercial use. You are responsible for having the rights to the input text and for using generated speech lawfully.
Shape vocal formants, register, breath, vibrato, envelope, stereo width, and melody, then export WAV, MP3, M4A, FLAC, or OGG.
Detect vocal pitch, snap notes to a musical scale, preview the correction, and export a mainstream audio format.
Use chipmunk, robot, demon, anime, deep voice, alien, radio, and advanced controls.
Choose from 28 American and British voices, adjust speed, preview, and export MP3 or WAV.
Upload or record speech, generate timestamped text, edit the transcript, and download TXT or SRT.
