Free browser text-to-speech with natural neural voices
Pick from neural AI voices with five reading styles so the output sounds like a person rather than a satnav, and set speed from 0.5x up to 2x.
Each sentence is highlighted while it is read, so you can follow along on screen, which is what makes it work for studying and proofreading by ear.
Paste plain text or upload a document, or drop in a link and the article text is extracted for you before playback.
Download the generated audio as an MP3 and keep it for commuting, the gym or any podcast app—no repeated regeneration needed.
Listen to PDFs, ebooks, and webpages in natural AI voices with synced highlighting.
As the document is read, sentences highlight in sync with the audio and the page scrolls automatically, so you never lose your place.
Six OpenAI TTS voices, including Alloy, Echo, Fable, Onyx, Nova, and Shimmer, cover neutral, narrative, and expressive styles for different content types.
Read in over 140 languages and dialects, with regional English, German, French, Spanish, and Chinese variants available.
Built-in filters skip footnotes, superscripts, and bracketed text, and you can manually exclude sections you do not want spoken.
