Why is the TTS quality in speaking mode so bad compared to the voice that you get when clicking on words for explanations? I like the principle of the reading mode, but at least for Slovak its quite hard to understand. However, the other voice used when getting translations of words is great. Can we get the better voice in reading mode as well?
The TTS used for the Read Aloud feature depends upon your specific device and browser. I’ve found the highest quality voices on Microsoft Edge browser for desktop.
The TTS used for speaking mode (which speaks the words and phrases you click on) is provided by MS Azure regardless of your specific device and browser. I’ve been thinking of adding these voices for Read Aloud as part of the Premium Plus plan (since I need to pay per character for this). No promises.
Change your browser to Microsoft Edge, the reading voices are great there.
I use mostly my iphone, and I believe all browsers use the system voice.
That’s true. On iOS all the browsers are forced to use the same underlying engine so the differences in many respects, including TTS voices, aren’t so great.
