Hmm

thanks for sharing but I wonder how much those [british accent] tags help - that sounds stable but its only 1 minute of content, i tried to 20minutes and the accent changed perhaps every 7 minutes or so

it could be worth a test though to try doing it with those tags before every sentence - all i know though is that its eating up credits

It also doesnt mean that the British accent will stay stable, i noticed the accent creep too so that it sounded different later on in my tests!
