compact auditory feedback mode

To enable faster real time auditory feedback for monitor mode.
Alternative option to pronounce the number in the following compact format:

Examples:
135 - one three five
48 - four eight
73 - seven three
8 - zero eight

The short beep signals the end of the current iteration.
This is much faster than to pronounce: one hundred thirty five, forty eight, seventy three etc.
It will simplify and speed up how the user can get auditory feedback
before the next feedback cycle.
The difference would be in milliseconds, but I consider it substantial for serious users.
