Transdev also use real voices for their announcements.
As of note, I think the latest Arriva Leicester streetdecks have forgot to install speakers upstairs (I've noticed zero!) because when I did a 74 reg electroliner on 127, only downstairs was working. Hopefully Salisbury Reds and Southern Vectis remember to install theirs upstairs before entering service
Other operators I've noticed in the past: Does anyone know if Blackpool still uses the 3 (or was it 4)-tone before every single announcement? I find that so annoying and needed to be removed.
Does any other operator have like a loud tone (like 2-tone, similar to East Midlands Airport "ladies and gentlemen...") at the very start of the route? I'm aware High Peak do (even Hulleys by High Peak).
Another observation (only happened once), was on one of the 73 reg Mansfield MMC's, even if a bus didn't stop, it still says "this is..." passing it, sometimes cut off as the next voiceover part was played.
Anyway our local network (NCT) now plays an announcement if a bus is on diversion, something they never did in the past. Trent also do but only if the drivers feel like pressing the button.
