or "ohty" instead of zeroty to avoid similarity between zero and zeroty?  but ohty sounds similar to eighty.

typically digit strings that are not numbers should be read as digit strings, but place value indicators inserted into the string serve as useful signposts.  in this case, also consider speaking internal zeroes: 

000000 zero hundred zeroty zero thousand, zero hundred zeroty zero
20 twenty zero

10 "ten" remains irregular.  though could we do something like 10 one-ty zero, 20 two-ty zero (future post knlwtvtb).
