I actually don't mind Anne. The recordings seem to be different at somewhere like Worcester Foregate Street than somewhere like Bristol Temple Meads though, the pronunciations seem a little different, and at the former for trains to Weymouth, she misses off "Castle Cary" when it's listed on the LED information system. It's slightly annoying how she says "Lawrence Hill" at this station too, where as at FGW land it's said clearly. She also says "This train has X carriages" rather than coaches in Worcester. I prefer her announcements at FGW stations though.
I really like the "Ruth" announcer (Arriva Trains Wales). We used to have her at some parts in the west country. She sounds so enthusiastic... I.e. "Platform ssssix for the sixteen OHHHH ONE Arriva Trains Wales service to BARGOED. Calling at Cardiff QUEEN Street, Heath HIGH level, Llanishen, Lisvane and Thornhill, Caeeeeerphillllyyy, ABER..." etc etc. It's just nice to hear and she doesn't dilly dally through all the welsh stations. However not liking her pronunciation of "Keynsham"...
