About Text to Speech

Text to Speech (TTS) is a technology that converts written text into spoken audio using a computer voice. It is widely used for presentation script review, language learning listening practice, accessibility support for visually impaired users, and listening to long articles while multitasking.

This tool uses the browser's built-in speech synthesis engine (Web Speech API SpeechSynthesis) to convert text to audio. It supports Japanese, English, and many other languages and voices available on your browser and OS. Voices are automatically grouped by language for easy selection.

You can freely adjust the speaking rate (0.5x to 2x), pitch (low to high), and voice type. All processing runs entirely within your browser, and your text data is never sent to any external server. Compliant with WCAG 2.1 AAA accessibility standards with full keyboard control support.
