Speech Studio
Text-to-speech and speech-to-text — powered by your browser, fully private.
Uses a neural TTS model that runs in your browser. First download is ~40MB (cached for future use).
Speech Studio uses your browser's built-in Web Speech API — no audio is ever uploaded to a server. The Text to Speech tab lets you choose from all voices installed on your device, control speed and pitch, and watch word-by-word highlighting as it reads. The Speech to Text tab uses your microphone to transcribe speech in real-time, showing interim (unconfirmed) results as you speak. Speech recognition is available in Chrome, Edge, and other Chromium-based browsers.
