As I’ve said before, I just love NVDA. And it has all the features I need being an average computer user. I do think that NVDA. Should add more of the

her added to NVDA. Without charge.  I think the original voices that NVDA. Had are now pasee and should be droped because their quality isn’t good anymore.
What do you guys think?

I think by "original voices", you mean Espeak.  That being the case, I couldn't disagree more.

Its quality may not be what you want, but Espeak, in my workflow, sounds much better and more clear at high rates of speed than OneCore does.  Plus, One Core is just not my cup of tea. Too many pauses, and it does weird things to some words.

How does it hurt anything to continue including Espeak?  It isn't the default, and if you don't like it, you don't have to use it.

Which is the point: different people like different things, and "most human like" of the voice is not a quality that everyone values or weights equally. Clarity and comprehensibility at significant rates of speech is much more interesting to me.

Plus, I'm pretty sure eSpeak supports many more languages than most of the higher quality voices, although I could be wrong about that by now.
