Description :
The Thai and Chinese languages are tonal languages. Tones are core of the language. Tones distinguish the meaning of one word from another. Thai and Chinese languages are two of the languages that use tones for communication. To speak Thai or Chinese correctly in terms of meaning the tones of the words must be pronounced correctly. This research work was to study the tone characteristics of Thai and Chinese languages using Fast Fourier Transform (FFT) to analyze the frequency patterns of the 5 tones in Thai language and 4 tones in Chinese language. Apart from the tone characteristics of these language, some animal sounds were also studied. Fast Fourier Transform takes a time-varying input signal and transforms it into a frequency spectrum. The voice signals of the various tones are recorded and analyzed. Each syllable is pronounced with one of five distinct tones – Mid, Low, Falling, High and Rising. There are 5 tones in Thai language. But there are only 4 tones in Chinese Language: Mid, Low, Falling, and Rising. From experiments, it was found that each animal species gives obviously different sound spectrum. Some animal sounds are compared between real animal sounds and imitating sounds of animals.
