Siri Voice - Different on MacBookPro/iPhone12 and iMacPro
I have the siri settings EXACTLY the same on all devices: English (US), American Female.
The MacbookPro's sounds smoother, more natural with inflections, etc. - same on my iPhone 12.
My iMacPro 1,1 OS 11.2 - sounds more synthesized and without natural inflections. I've tried changing to other voices, then back. No difference.
Any other ideas?
