The Pinyin Tutor website includes two components. First, there is a set of web pages that summarize the rules of Pinyin and allow students to test out and here the pronunciation of each possible Chinese syllable. Sound playback relies on a Flash plug-in, so no special software is needed, as long as the student’s computer has a recently updated web browser. The second component of the Tutor is a set of lessons that train the student to produce correct Pinyin forms for both old and new words they hear over the browser. The student is prompted by an audio recording of a word in Standard Chinese after which they must correctly enter the Pinyin for this word. If correct, the student progresses to the next trial; if incorrect they are given a second chance, along with diagnostic feedback regarding the difference between their form and the target. If they fail on the second attempt, the application remembers the incorrect word and presents it again later. On each trial, students also have the option of comparing the sound of the Pinyin that they typed with the target sound following each of the two Pinyin entry attempts.
