Thai intonation can be categorized as paralinguistic information of F0 contour of the utterance. There are three classes of intonation pattern in Thai, the Fall Class, the Rise Class, and the Convolution Class. This paper presents a method of intonation pattern recognition of Thai utterance. Two intonation feature contours, extracted from F0 contour, were proposed. The feature contours were converted to feature vector to use as input of neural network recognizer. The recognition results show that an average recognition rate is 63.4% for male speakers and 75.4% for female speakers. The recognizer can recognize the Fall Class from the others better than distinguish between the Rise Class and the Convolution Class.
