i can give you work around.
Copy your text into notepad save it as .txt file.
open edge and drag that file into edge. at end of address bar is readout loud.
install Microsoft Jenny natural TTS in windows 11 speech settings and you can pick TTS voice in edge to get same result.
Track your text in Word when you listen in edge and correct mistakes.
its off in word you can pick male / femal thats it. when you use that feature in crome you can pick any language pack voice you have installed and force it to that voice.
The Jenny voice (among others) is part of the Narrator feature in the speech settings. I've toyed with it in the past, but I don't like how it announces every little thing on my screen. Also, you need to manually scroll line by line for it to read anything. What I like about Read Aloud is I hit a button and let it go, and it helps me proofread stuff. Although the Jenny (and also the Aria) voice does sound good.
A better solution would be to use only ONE language feature, rather than trying to bug-fix so many odd redundant things like this. Word with Read Aloud, Settings with Narrator, etc. Use just one and make it a system default for everything, so you have less work to monitor. How hard can it be for MS to tie in the Narrator feature to Read Aloud. It's all MS anyway, and probably better than trying to program an independent feature in Word alone. Then you just set one voice for all of it and boom, done. And you have nice voices to use anywhere.
And if something breaks, it's easy to figure out which one it is, as there's only one to look at.
