Abstract：The identification of six pairs of Korean and Chinese monophthongs which are similar in pronunciation is studied based on formant. Firstly, the first three formant F1, F2 and F3 in audio file are extracted; secondly, the differences between the formant distributions of the six pairs of monophthongs are examined, and different characteristic parameters of formants or their combination are employed for different objects as classification feature; at last, the classification threshold is determined by using information gain. The experimental results reveal that the Korean monophthongs and Chinese monophthongs with similar pronunciation can be distinguished by the method proposed in this paper.
