摘要
目的分析正常青年人不同语料测试的平均基频,探讨适合测试言语基频的语料形式。方法应用Praat软件对60例正常青年人(男22例,女38例)发元音/a/、/i/、/u/和朗读短文的声样进行录音,并选取稳定段分析其基频。结果正常青年人发/u/和/i/的平均基频最高,/a/次之,朗读短文的基频最低;男生发/u/、/i/、/a/及朗读短文的平均基频依次为148.47、146.77、136.33、132.85 Hz,女生依次为:257.39、250.52、239.43、222.16Hz,男生发/a/音的平均基频低于发/i/、/u/音,差异有统计学意义(P<0.01),但与朗读短文的平均基频差异无统计学意义(P>0.01),女生不同语料测试的平均基频之间差异均有统计学意义(P<0.01)。结论朗读短文的形式可更准确地反映正常人的习惯基频,而测试语料为元音时,元音/a/更合适。
Objective This study is to analyze the fundamental frequencies of different speech materials.Methods 60 normal subjects（22males,38females）were studied.When pronouncing/a/,/i/,/u/and the short paragraphs,the fundamental frequencies were measured using Praat software.Results The analysis of the fundamental frequencies for different materials indicates that/i/and/u/were the highest while/a/was the next and the paragraphs were the lowest.For males,the fundamental frequencies from high to low were：148.47 Hz,146.77 Hz,136.33 Hz,and 132.85Hz;for females,they were：257.39 Hz,250.52 Hz,239.43 Hz and 222.16 Hz.The experimental results showed that there was no significant difference between the fundamental frequencies of vowels between the two genders but there were significant differences when pronouncing different vowels among the female subjects.Conclusion When measuring fundamental frequencies,reading short paragraphs can be more accurate and the vowel/a/is more useful in this purpose.
