Units Improvements

Opened this issue 4 years ago · 2 comments

Move over some of the MathSpeak rules to Clearspeak (#358)
Check plural considerations (#301)
Add currencies.
Integrate PossibleUnit heuristic.
Finish new SI unit handling on all locales.

I was looking at MathSpeak vs Clearspeak rules and how they dealt with imperial units and found a few oddities. Some common units are missing and pluralization is off in a few places as well. I was working up some examples and thought I'd share here. I hope you find this useful, even if just for testing.

Answer 2 · 2020-05-25T03:47:39.000Z

Thanks @klobetime for all these Imperial measures. Some were quite new to me!
I have just pushed a v3.0.1 release which contains a number of fixes for units.

As for Mathspeak vs Clearspeak; Mathspeak is the more literal of the two grammars, there are a couple of points that are worth pointing out:

All units are always spoken in plural form; Rule 13.1.
Powers are not interpreted wrt. the unit. I.e., it is meters squared and not square meter (Examples 5 above)
Symbols are not interpreted as units, i.e., the primes will be spoken as primes.
