Formule & Méthode de Calcul
Tampon audio = SpeechSynthesisUtterance(Texte) ➔ Moteur vocal du système (Hauteur + Débit)
The browser does not contain audio files. It passes the text string to your device's native operating system (Windows Narrator or macOS VoiceOver), which mathematically generates the sound waves in real time.
Bonnes Pratiques & Conseils
- Optimize the Speech Rate: The default speed (1.0x) is often too slow for intensive proofreading. Adjusting the rate to 1.2x or 1.5x allows for rapid auditory scanning without sacrificing phonetic clarity.
- Use for Proofreading: When you read your own writing, your brain automatically 'fixes' typos and missing words. Listening to a computer read it aloud forces you to hear exactly what is on the page, instantly exposing grammatical errors.
- Adjust Pitch for Clarity: Raising or lowering the pitch slider alters the simulated vocal tract length. Slight adjustments can make robotic synthetic voices sound vastly more natural and easier to comprehend.
