Let Fonoguru solve your phonology assignment! Simply input a set of phonetic data, and click a button, Fonoguru will automagically determine whether two or more phones are separate phonemes or allophones of the same phoneme, and state the conditioning environment for you.

A neat utility for revising the International Phonetic Alphabet (IPA), or simply use it as a reference tool. You can even listen to the pronunciations of the symbols in the charts of Pulmonic Consonant and Vowel.
