Text to Speech
Text to Speech converts written text into spoken audio directly in your browser using the Web Speech API — no server, no uploads, no data leaves your device. Simply type or paste any text, choose a voice from the list of voices installed on your operating system, and adjust the speaking rate and pitch to your preference before pressing Play.
This tool is ideal for proofreading documents by ear, creating quick audio previews, assisting users with reading difficulties, or testing how content sounds before recording a professional voiceover. Because it relies entirely on browser-native synthesis, it works offline and is completely free with no usage limits.
How it works
No mathematical formula applies. The browser's SpeechSynthesis API tokenises the input text, maps phonemes to the selected voice model, and applies the rate (0.5×–2×) and pitch (0–2) parameters to the generated audio waveform in real time.
Use cases
- Proofreading long articles or reports by listening instead of re-reading
- Assisting people with dyslexia or other reading difficulties
- Previewing how a script or presentation sounds before recording
- Language learners checking pronunciation of foreign-language text
- Accessibility testing to verify how screen readers interpret content
