การเปรียบเทียบปฏิสัมพันธ์ระหว่างค่าความถี่มูลฐานและค่าระยะเวลาของเสียงสระกับเสียงพยัญชนะท้ายในภาษามลายูถิ่นปัตตานีที่พูดในจังหวัดปทุมธานีกับจังหวัดปัตตานี : การศึกษาทางกลสัทศาสตร์ / กุสุมา เลาะเด = A comparison of the interaction between the fundamental frequency and duration of vowels and final consonants in Pattani Malay spoken in the provinces of Pathumthani and Pattani : an acoustic study / Kusuma Lohde
In this research, we aimed at analyzing and comparing the fundamental frequency (F0) and duration of vowels preceding the following consonants: -?, -h, -ŋ and -Ø in Pattani Malay language, spoken in the provinces of Pathumthani and Pattani in Thailand. We collected data from 20 Pattani-Malay speakers of Pathumthani, and the other 20 speakers of Pattani. Each speaker pronounced 40 tokens with different final consonants in citation form. Each token was measured for the F0 values and for its vowel duration in the Praat sound analysis program. All the values gained from the Praat program were entered and analyzed in the Microsoft Excel 2000. In this study, it is found that the fundamental frequency of the vowels preceding finals such as -? and -h was significantly higher than vowels preceding final - ŋ and without any final -Ø, for Pattani Malay tokens both spoken in the provinces of Pattani and in Pathumthani. It is also found that pitch of vowels of Pattani Malay tokens, spoken in Pathumthani, can be divided into two groups. The first group contains tokens with high pitch on vowels preceding finals - ? and -h and the other group has low pitch on vowels preceding final - ŋ and without any final. Furthermore, this study revealed that pitch of vowels of Pattani Malay tokens, spoken in Pattani, can be divided into three groups. The first group has tokens with high pitch on vowels preceding finals -? and -h, the second group is with mid pitch on vowels preceding final - ŋ, and the third group is with low pitch on vowels without any final. As for vowel duration, it is found that the duration of vowels preceding finals -? and -h is significantly shorter than vowels preceding final - ŋ, and without any final -Ø, both in Pattani and in Pathumthani. The results show further that the phonetic short-long duration of vowels in Pattani Malay spoken in both provinces can be divided into two groups: the group with short vowels which precede finals -? -h and the other group with long vowels which precede final - ŋ and without any final consonant. In summary, the results of this study showed that there is an interaction between the fundamental frequency and duration of vowels in Pattani Malay spoken in both provinces. That is when the fundamental frequency is high, the vowel duration becomes shorter, and when the fundamental frequency is low, the vowel duration is longer.
