Add "Natural" TTS voices to Reader Mode

[blackdagor_28]

For those who use Firefox's Reader Mode, especially Text To Speech, I think it would be a good idea to add some "natural" voices to Reader Mode, and make the distinction between Offline and Online Voices, Offline Voices (system voices) are robotic and sometimes fails to speak words or to pronunciating them well, so, being a browser with 20+ years, Firefox needs to have more innovating features and not going backwards, it would be a good Usability and Accessiblity feature that other browsers like Edge has (the only browser which can be compared with Firefox in terms of features), and Audiobook listeners will be very thankful for this.

I appreciate anyone who could find this a good idea, thank you so much.

100% agree on updating these. I always want to use this feature, then encounter it and realise the voices are so bad, then don't use the feature. And switch to Edge.
