I imagine you could easily create different scenarios and then record/evaluate. I do seem to remember seeing such a thing for giving public speeches where it'd put you in front of a virtual crowd to give remarks. The demo I saw even looked for keywords like uh's or ums etc and gave realtime feedback. I imagine you could do something similar for general speech quality but I wouldn't know how you'd quantify what's good and bad in a way that could be measured. Perhaps pitch and tonality but is that what really makes a voice pleasant? Who's to say it's quality as much as charisma, energy, rhythm, etc.

I imagine VR speech therapy would be incredibly viable if you knew how to approach it. For that matter so would many types of psychotherapy, curious when the first doctor will start taking actual patients in VR.
