A Web-based Talking Dictionary with Visual Corrective Feedback on Learner's Spoken Mandarin

Project: Research

View graph of relations



The merit of the web-based talking dictionary is that it can display the intonation, loudness and duration of an input utterance as a curve (hereafter called tonal-graph) with varying level, width and length. The software runs as follows. First, a learner inputs any Chinese characters, words or sentences in written form. The system then plays back the correct pronunciation of the input. At the same time, a reference tonal-graph of the input is displayed in the upper half of the computer screen. When the learner imitates the system's audio output, the tonal-graph of the learner's utterance is displayed in the lower half of the screen. In addition, the system points out the positions of the learner's pronunciation faults, and scores the learner's utterance. By comparing the differences between the two tonal-graphs, the learner can realize his/her pronunciation faults and make more practice to correct the faults.This project aims at developing CLU Putonghua course, which is a non-credited Putonghua elective course at City University. At the same time, outcome of the project can help all the Putonghua learners of City University to correct their Putonghua pronunciation. (To our knowledge, there is no such kind of software in the other Mandarin Society)
