rhymer is a utility written in C++ for the purpose of finding rhymes given a dictionary of words to phonemes like the one found here.

Rhyming words are defined having their tail phonemes match, starting from the last vowel phoneme. For example, "orange" (AO1 R AH0 N JH) and "challenge" (CH AE1 L AH0 N JH). Vowel phonemes are defined here.

As an option, rhymes may not match the stress value of the last vowel phoneme. For example, "orange" (AO1 R AH0 N JH) and "sponge" (S P AH1 N JH).
