Pitch Perfect Pinyin is to be a two-part interactive website for learning Pinyin pronunciation. It is part of COERLL’s Gateway to Chinese project. Currently the first part, Learning, is operational; the Practice part is incomplete at this point. Students can hear syllable pronounced and then hear words for practice.
