A Phoneme is the smallest unit of speech that can be used to make one word different from another word.

In this module, you can practice recognizing aUI phonemes.  Test your ability to understand spoken aUI!  Match a sound with its aUI symbol or its roman letter equivalent.  Questions come in a random order that changes every time you do this activity, so it might help repeat it as you become more and more familiar with the sounds and meanings of the language.
