摘要
本研究对听力正常的说话人在同步交流中产生的言语的语速和语音起始时间进行了研究。用发声爆破和不发声爆破启动的刺激词被嵌入在用SC说话和产生的句子中。VOT测量从录音中计算出来,结果表明语音和SC条件之间存在显著差异,在SC过程中产生的语音显示出说话速度变慢和不发声辅音的VOT增加。在SC和纯语音条件下产生的vot都遵循英语发音规则,并随着发音位置的不同而适当变化。SC过程中略微放大的发声对比与先前关于语率变化对言语时间精细结构影响的研究结果一致(Miller, 1987),与Picheny, Durlach, and Braida(1986)报道的清晰言语的发声对比结果相似。
Voice onset time in speech produced during simultaneous communication.
This study investigated speaking rate and voice onset time (VOT) in speech produced during simultaneous communication (SC) by speakers with normal hearing. Stimulus words initiated with voiced and voiceless plosives were embedded in a sentence that was spoken and produced with SC. VOT measures were calculated from acoustic recordings and results indicated significant differences between speech-only and SC conditions, with speech produced during SC demonstrating both slower speaking rate and increased VOT of voiceless consonants. VOTs produced during both SC and speech-only conditions followed English voicing rules and varied appropriately with place of articulation. The somewhat enlarged voicing contrast during SC was consistent with previous findings regarding the influence of rate changes on the temporal fine structure of speech (Miller, 1987) and was similar to the voicing contrast results reported for clear speech by Picheny, Durlach, and Braida (1986).
