Ah yes, you're right w3w has an enormous wordlist which isn't great. The metaphone wordlist I was talking about is verbal-id https://github.com/bandrews/verbal-id#readme https://github.com/bandrews/verbal-id#readme which shouldn't suffer from the problems you mention. > verbalid.parse("vacant brand orchestra kiwi") '8aab9b999' > verbalid.parse("vaycant brahnd orchistra keewee") '8aab9b999' My own wordlist has 'flower' but not 'flour', neither 'ants' nor 'hence', none of 'its', 'hits' or 'tits', neither 'lead' nor 'led', and 'let' but not 'lit', precisely because of the problems you mentioned. I went through my wordlist automatically first of all (with soundex filtering), then manually afterwards, trying to spot all of these problems and removing them.
