Text to Speech

Text to speech (TTS) converts written text into spoken audio. This free tool does it entirely through the Web Speech API that ships inside modern browsers, so it uses voices already installed on your computer or phone rather than a paid cloud service. You paste text, pick a voice, set the speaking rate and pitch, and the browser reads it aloud through your speakers. Because the synthesis happens on your own device, the words you type are never uploaded to a server, which matters for confidential emails, unpublished drafts, and private notes. The voices you can choose from depend on your browser and operating system, not on this tool. Chrome on Windows typically exposes around twenty system voices, macOS Safari and the Mac system add many high-quality neural voices, and Edge can surface additional online voices. That is why the dropdown looks different on different machines, and why some voices read instantly while others briefly buffer. The rate slider controls how fast the voice speaks and the pitch slider raises or lowers its tone, which is useful for slowing down a language-learning passage or speeding up a long article you want to skim by ear. Common uses include proofreading by listening for awkward sentences your eyes skip over, accessibility testing, hands-free reading of documents while you do something else, and checking the pronunciation of unfamiliar words. One honest constraint: the Web Speech API streams audio straight to your speakers and does not expose a downloadable file, so there is no built-in MP3 export. If you need an audio file, a paid TTS API is the right tool. For listening on demand, in private, with no quotas or watermarks, the browser-native approach is hard to beat.
