Problem statement: Tone of a tonal language is an important feature of a prosodic syllable to identify the meanings of that syllable or that part of word. Ii is very crucial to model the feature related to tone of speech to achieve the most naturalness in speech communication. Approach: The study presents an approach to analyze the model parameters of Thai tones for two genders. The successive modeling of fundamental frequency, Fujisaki¬ís model is selected. We derive seven parameters; baseline frequency, the numbers of phrase commands and tone commands, phrase command and tone command durations, amplitudes of phrase command and tone command. Results: In the experimental results, there are 20 syllables and each syllable includes 50 samples of a tone with male and female speech. Five tones are recorded in the same environment. Thereafter, there are ten thousands samples in the speech corpus. It can be obviously seen that Thai tones are determined by the derived parameters. Conclusion: All in all, Thai tones are able to be discriminated by the derived parameter of Fujisaki¬ís model."
