摘要
在五种不同的发音方式(大声、正常、小声、加快和放慢)下,研究说话声级、说话速度和言语基频F_O之间的相互作用。发音人一男一女,言语材料为四个元音/a,i,u,u/,在不同声调下嵌入负载句。结果表明:1.说话声级提高导致基频升高、音域扩大,说话速度变化对基频影响较小,只是速度加快音域下限略有上升;2.单句的起始基频主要决定于说话声级;3.单句的基频F_O下降率既与说话速度又与说话声级都有关系;4.句尾基频跟说话方式关系不大。
The interaction between speech level, speech rate, and fundamental frequency F0 was investigated under five different speech styles (loud, normal, soft, fast, and slow) by using four Chinese vowels /a, i, u,y/ with four tones embeded in a frame sentence respectively. Two speakers (one male and one female), who are native of Beijing, were recorded in a listening room. The results show that: 1. The pitch range is moved up and enlarged as increasing the speech level, 2. The lower boundary of pitch range is somewnat moved up as increasing the speech rate, 3. The onset F0 of the sentence is mainly dependent on tne speech levels, 4. The declination rate is related to both speech level and sentence length, 5. The sentence final F0 is almost invariant in different speech styles.
