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 converte testo scritto in audio parlato utilizzando l'API Web Speech Synthesis integrata nel tuo browser. Scegli tra tutte le voci di sistema disponibili raggruppate per lingua. Regola la velocità del parlato (da 0,5x a 2x) e il tono. Lo strumento evidenzia la parola corrente mentre legge. Supporta decine di lingue tra cui inglese, spagnolo, francese, tedesco, giapponese, cinese, hindi e arabo. La maggior parte delle voci viene eseguita sul dispositivo senza chiamate di rete. Il testo lungo viene automaticamente suddiviso in blocchi gestibili.
How It Works
Lo strumento utilizza l'API Web Speech Synthesis (SpeechSynthesisUtterance) integrata nei browser moderni. Interroga le voci disponibili tramite speechSynthesis.getVoices(), applica le impostazioni di velocità/tono e legge il testo ad alta voce con evidenziazione a livello di parola.
