Phonetic Matching

This is one of these cases where inheriting hacked-together piece of crap (English spelling) makes a lot of additional work higher up.

Another example is poetry. A regex can find rhymes in Polish. Same postfix == it rhymes.

In English it's a feat of engineering.

It's really just a feat of data collection (e.g. rhymezone.com). You just compile all English words and record which ones rhyme with which.

(Yeah it's labor-intensive, but probably not moreso than, say, writing a dictionary.)

I suppose, if we ignore accents and heteronyms... both of which English is famous for, unfortunately!
