I'm assuming this is a voice bot?
Are you using native Genesys language engine, enhanced tts, or byot?
I have certainly not experienced a 19 second or longer delay at all. I would take a look at your end of input timeouts under Settings > Actions
As for registering the case number, not sure, could be the language engine you are using, if possible try another eg through Enhanced TTs.
Another option might be to break it down, ie first say the first digitis before the letters, then say the letts, then say the rest, and then combine the string after.
Might be some other options out there.
