There should be a monospace voice mode where saying any number of equivalent digit length takes the same time
@nyastrid just use sept or s'ven for 7, then is just works out
6969 -> six thousand nine hundred and sixtynice
1073 -> one thousand nil hundred and s'ventythree
1212 -> one thousand two hundred and tenty two
@nyastrid "twenty, done" and "twenty s'ven"
