Hi Wolfgang,
We tested this proposal and checked with several screenreader users, you can see the thread:
https://github.com/w3c/wcag/issues/1117
The recommendation was not to make this change, for the reasons outlined in this comment:
https://github.com/w3c/wcag/issues/1117#issuecomment-1059303545
It is an area that needs improvement though and there is a "Pronunciation Gap Analysis and Use Cases<https://www.w3.org/TR/pronunciation-gap-analysis-and-use-cases/>" doc from the W3C. This might be a good use-case to mention.
If you wish to pursue it, I suggest raising an issue (i.e. this use-case) for that document:
https://github.com/w3c/pronunciation/issues
Kind regards,
-Alastair

Subject: correct character for (contrast) ratio
Please use the correct character code for ratio (e.g. 3กร1 and not 3:1)!
WCAG 2.1 and the working draft for WCAG 2.2 use : but it should be กร (∶ or ∶).
Visually both look nearly the same, but good screen readers announce them differently.
