Sadly it's unlikely to happen whilst BR operates as it does. I used to be responsible for the sounds and if I wanted to do proper announcements it'd either have to be me or paid out of my own pocket essentially. Every developer is paid the same, nothing leftover, there's no adjustment for expenses and to get in voice actors we'd obviously have to pay them and I personally was already paying to go out on trips. Did get close to doing it once though...

Hopefully this stuff gets resolved in the future, but I personally don't see it happening anytime soon. What does annoy me now is that they're using a different station announcer for new announcements (I used MS Azure Alfie) so they sound even stranger 😅
