Abstract

The objective of this research was to investigate the acoustic characteristics of tones in Bangkok Thai spoken by three different age groups. 50-60 years (x equal 54), 30-50 years (x equal 35) and 10-20 years (x equal 16.5), in order to determine whether there was variation by age group, and if so what is the pattern of this variation. The acoustic characteristics under study are the x of the fundamental frequency, the range of the fundamental frequency, the shape of the fundamental frequency, and the duration of the fundamental frequency of the 5 tones spoken in citation style. The wordlist consists of 31 one-syllable words with all the 8 possible syllable structures in Thai. The test words all have aspirated and unaspirated stop initial consonants with low-mid vowels. The subjects were 30 speakers from the three age groups coming from similar speech communities. The corpus of data comprises some 930 token words. (310 words for each age group). The spectrographic analysis of the 930 token words was carried out and decriptions of the acoustic characteristics of the tones of the three groups given. In the study of the variation of the acoustic characteristics of the 5 tones of the three age groups, trend analysis operating with a significance level of p equal .05 was done by GANOVA. The results of the research are as follows: 1. With one exception, the patterns of acoustic characteristics of the 5 tones spoken by the 50-60 year group and the 30-40 year group are not significantly different. The exception is the range of the falling tone in long dead syllable shows significant difference between these two age groups. (p equal .04) 2. The x of fundamental frequency of the 5 tones spoken by the 50-60 year and the 30-40 year groups are significantly different from that spoken by the 10-20 year group. 3. The range of the fundamental frequency in the high tone and the falling tone of the 50-60 year group and the 30-40 year group are significantly different from that of the 10-20 year group. 4. The shape of the fundamental frequency in the high tone and the falling tone of 50-60 year and the 30-40 year groups are significantly different from that of the 10-20 year group. 5. The duration of the fundamental frequency in the mid tone, the high tone and the falling tone of the 50-60 and the 30-40 year groups are significantly different from that of the 10-20 year group. 6. The range of the fundamental frequency and the shape of the fundamental frequency of the low tone, the mid tone and the rising tone show no significant difference due to age
