Mozilla TTS has not been updated in 4 years (at least). The quality of the sound generated is rather poor, or at least I was not able to generate human passable sound using that tool.

OpenVoice, as you very well mentioned, needs to become more mature before it can be used for the purpose I have in mind, as it shares the same poor quality that Mozilla TTS does.
I am currently playing with F5 which even has online tutorials: https://www.youtube.com/watch?v=ASFoTNpkM8o
It seems quite decent. I was able to run it on my local setup as well, which is a big plus. The problem I now face if twofold:
- I need to find a voice database with male voices in English (have no idea where to find one)
- I need to then train F5 or whatever tool I use with that voice
As a final step, I will also then need to learn and manipulate said tool to read paragraphs, instead of 1 liners.
