Mark II Voice Change -- more info

I’m having same issue as Colin (1 Nov). I’ve tried making any number of variations on "mimic --voice ‘en_US/#p###’ " but none work except those s that only have one speaker (e.g. no need for the “p###” part of the command.
Does the mark II use a different syntax in the .config file?
Are there some other changes needed?

Mr. Pope is fine for a short period, but not who I want to live with.
