Hi Based on only dimly remembered conversations long long ago:
Getting all the “message fragments” so they sound natural and not choppy is not quite as easy as it seems at first. It’s by not quite rocket science, but there is more fiddling involved than one might think. One “solution” is to use fewer fragments and record larger portions of the message. Back in the day, storage limited your ability to record every message “full up”. Assuming you record the “at the stroke the time will be” only once, the rest is under 3 seconds of audio. At maybe 16 bits / 32K sps. (yes that’s overkill). this comes up just under 200 K bytes. Recording the full time message for every minute of the day would be less than 270 megabytes. That’s a pretty small flash drive ….
