Oh dear God I want that so much. It's invaluable to driving to know who calls so you know whether to ignore and call later or if it's an emergency or if it's worth getting up.

I would certainly buy/donate on that.

I'm thinking it can be worked around via a ringtone that naturally mutes/fades to lower from second 2 to second 5, allowing the speech synth to be heard. One still needs the hook for the ringing event. I saw voice synth is already available via CLI so that should be easy.

Just execute the CLI command on second 2 and remember to break it if there's answer event - you don't want voice-over-voice.

I can live with a sagging volume curve ringtone.
