À propos de cet outil

This reads text aloud using the speech synthesis engine already built into your browser and operating system. That has a practical consequence worth knowing: the available voices come from your device, not from this site, so a Mac, a Windows PC and an Android phone will each offer a different set - and the quality varies with them. Modern system voices are considerably better than the robotic synthesis people remember. The most valuable use is not accessibility but proofreading. Reading your own writing silently, your brain supplies what you meant rather than what you typed, which is why typos survive several careful reads. Hearing it spoken breaks that: missing words, doubled words, and sentences that run too long become obvious immediately. Note that this plays audio live and does not produce a file - if you need a downloadable MP3, the Text to Speech (MP3) tool is built for that. Everything runs on your device.

Comment utiliser cet outil

  1. Paste your textA paragraph, an article, or a full document.
  2. Pick a voiceThe list comes from your own operating system, so the options differ by device.
  3. Adjust rate and pitchSlower helps for proofreading; faster suits listening through longer content.
  4. ListenPlayback is live. For a saved audio file, use the Text to Speech (MP3) tool instead.

Pourquoi l’utiliser

  • Catches typos and clumsy sentences that silent reading reliably misses.
  • Uses your system voices, which on current devices sound markedly better than older synthesis.
  • Runs entirely on your device - nothing is uploaded, so drafts stay private.
  • No account, no character limit and no per-use charge.
  • Works offline once the page has loaded.

Usages courants

  • Proofreading your own writing by ear before publishing.
  • Listening to an article or document while doing something else.
  • Checking how a script or speech sounds when spoken aloud.
  • Making written content accessible for someone who prefers listening.
  • Practising pronunciation in another language using a native voice.

Conseils pour de meilleurs résultats

  • Slow the rate down when proofreading. At normal speed your ear glides past small errors the same way your eye does.
  • Try more than one voice - quality varies substantially between the voices your system provides.
  • Break long text into sections. It is far easier to re-listen to one paragraph than to scrub through a whole article.
  • If you need a file rather than playback, use the Text to Speech (MP3) tool, which is built for export.
  • Voice availability depends on your operating system, so a colleague on a different device will see a different list.

Erreurs à éviter

  • Expecting a downloadable file from this tool. It plays live only - the MP3 tool is the one that exports.
  • Assuming everyone sees the same voices. They come from the device, not from the site.
  • Proofreading at normal speed, which defeats much of the benefit.
  • Pasting an entire book at once rather than working through it in sections.
  • Expecting correct pronunciation of unusual names and technical terms - synthesis guesses from spelling.

Yes. No account, no character limit and no per-use charge, because the synthesis runs on your device rather than on a paid service.

Not from this tool - it plays live only. The Text to Speech (MP3) tool produces a downloadable file, which is the one to use if you need to keep the audio.

Yes, from whatever your operating system provides. That list differs between Windows, macOS, Android and iOS, so the options you see depend on your device rather than on this site.

No. Synthesis happens locally in your browser, so unpublished drafts and confidential documents never leave your device.

There is no hard limit, though very long passages are easier to work with in sections - re-listening to one paragraph beats scrubbing through an hour of audio.

Because synthesis infers pronunciation from spelling, which fails on unusual names, acronyms and technical terms. Spelling a word phonetically in the text is the usual workaround.

Yes. Text To Speech is free for normal use with no account required, and ToolBox does not add a watermark to your result.
