Text to Speech

Text-to-speech (TTS) is a type of assistive technology that converts written text into spoken audio. It is used to improve accessibility for people with visual impairments or reading difficulties, aid language learning, review written content by listening, and create audio from scripts or documents. Modern TTS engines produce natural-sounding speech by modeling human vocal patterns.

The Web Speech API is a browser-native JavaScript API that provides speech synthesis (text-to-speech) and speech recognition capabilities. The SpeechSynthesis interface allows web applications to convert text into spoken audio using the voices installed on the operating system. It requires no external libraries, server calls, or API keys — everything runs locally in the browser.

The SpeechSynthesis API is supported in Chrome (desktop and Android), Edge, Safari (desktop and iOS), Firefox, Opera, and most modern Chromium-based browsers. Internet Explorer is not supported. The available voices and quality vary by browser and operating system. Chrome and Edge typically offer the widest range of high-quality voices. On mobile, iOS Safari and Android Chrome both support the API.

Common use cases include: proofreading written content by listening for awkward phrasing, accessibility aids for people with dyslexia or visual impairments, language learning and pronunciation practice, converting articles or scripts to audio for multitasking, creating voice-overs for informal projects, and auditory review of drafts before publishing. It works with any text — paste an email, article, speech, or document.

No. This tool uses the browser's built-in Web Speech API, which processes text entirely on your device using locally installed OS voices. No text is transmitted to any server, stored, or logged. Everything happens client-side in your browser. This makes the tool safe for sensitive or confidential content.
