It's a somewhat hidden feature in Edge as we speak all you have to do is right click anywhere and select 'Read Aloud' from the drop down menu. The Edge 'Read Aloud' feature only goes up to 2X speed and theres no known way yet to increase the speed if its too slow for you but it's better than that robotic bullshit built into the ebook reader accompanied with Calibre lol. To go a step further, I use Calibre Companion on both Android and iOS on the go which syncs my Calibre library and I have all of my eBooks (AZW3, mobi, epub etc) converted to PDF for this reason so that the new Edge browser can read out my books. On mobile it works the same, choose Edge to open all PDF files so you can do TTS.

So you could open the file in the web browser and have it read aloud to you or do the same on mobile.

The Edge browser is available on desktop PC, iOS, MacOS and Android that I know of. The new Edge browser has a free built-in 'Read Aloud' feature containing dozens of premium and natural sounding voices for free and it's unlimited obviously. Then open the PDF-converted eBook in Microsoft's new Chrome-based Edge browser. If you already use Calibre, simply convert the eBook file to the PDF format specifically. There may well still be problems with the DeDRM plugin. Calibre 6.8.0 new features: Allow customizing the buttons available to the right of the search bar in the main calibre window via Preferences->Toolbars & menus->The buttons on the searchbar. For calibre 4.23, you must use the 6.8.1 DeDRM plugin, but the included Obok 7.1.0 plugin should work with calibre 4.2.3. The voice is just as natural as Apple's Siri or Amazon's Alexa in my opinion. It includes the DeDRM and Obok plugins, versions 7.1.0.

Calibre 6.23.0 instal the new
