The best free text-to-speech for Chrome is already installed

If you search the Chrome Web Store for "text to speech," you will find dozens of extensions. Most of them are wrappers around the same API that Chrome already exposes to every web page. Some of them cost money. Some of them send your text to a server you do not control. All of them are unnecessary.

Chrome ships with a free, built-in set of voices that any website can use through the Web Speech API. On Windows, Mac, and Linux desktop, that set includes voices labeled "Google US English," "Google UK English," "Google 日本語," and dozens more. These are the same neural network voices that Google sells as WaveNet on Google Cloud — except in Chrome they are free for anyone with an internet connection.

They are not perfect. The 14-second cutoff bug is real. The list of voices is not stable across Chrome versions. Some of them require Chrome to call out to Google's servers, which leaks your text out of the page. But for the common case — listening to a news article, an email, a chapter of a book — they sound great and cost nothing.

If you want to use them right now, the fastest way is to open any TTS tool that uses the Web Speech API (Wordcast is one) and start listening. The site will detect your installed voices and let you pick one. No signup, no install.

If you want offline-only voices and you are on Mac, switch to a voice without "Google" in the name — those use macOS Siri voices and run entirely on-device. On Windows, the Microsoft Natural voices give you the best balance: they sound nearly as good as Google's neural voices, and Edge can use them without sending your text anywhere outside Microsoft's read-aloud pipeline.

The takeaway: stop paying for what your browser already gives you for free.
