First use downloads 63MB - after that it's cached forever.
How it works
100% on-device: Voice models are downloaded once, then cached in your browser's Origin Private File System. No text or audio is ever sent to any server.
Powered by Piper TTS - a fast neural TTS engine from the Rhasspy project. Voice models are open-source (MIT) and hosted on Hugging Face.
Works on every device: Chrome, Safari, Firefox, Edge - desktop and mobile. No microphone or special permissions required.
Your text is processed locally on your device. OptiPix never sees what you type.

About Text to Speech
Last updated: May 2026
OptiPix Text to Speech converteert geschreven tekst naar gesproken audio met behulp van de Web Speech Synthesis API die in uw browser is ingebouwd. Kies uit alle beschikbare systeemsystemen, gegroepeerd per taal. Pas de spreeksnelheid (0,5x tot 2x) en toonhoogte aan. De tool markeert het huidige woord terwijl het leest. Ondersteunt tientallen talen, waaronder Engels, Spaans, Frans, Duits, Japans, Chinees, Hindi en Arabisch. De meeste stemmen draaien op het apparaat zonder netwerkoproepen. Lange tekst wordt automatisch opgedeeld in beheersbare stukken.
How It Works
De tool maakt gebruik van de Web Speech Synthesis API (SpeechSynthesisUtterance) die is ingebouwd in moderne browsers. Het bevraagt beschikbare stemmen via speechSynthesis.getVoices(), past uw snelheids-/toonhoogte-instellingen toe en leest de tekst hardop voor met woordniveau-markering.
Use Cases
- •Laat artikelen hardop voorlezen tijdens multitasking
- •Proeflees schrijven door te luisteren
- •Uitspraak voor taal leren
- •Toegankelijkheid voor slechtziende gebruikers
