四个实验证明了韵律结构对言语产生的影响。实验1 - 3采用斯滕贝格等人（1978，1980）准备的言语产生范式的修改版本来寻找句子产生的最后阶段韵律结构产生的证据。实验1提供的证据表明，准备句子生产潜伏期是一个功能的语音单词的数量，句子包括当句法结构，词汇项目的数量和音节的数量保持不变。实验2表明，实验1中的产出延迟确实是由韵律结构决定的，而不是由句子所包含的实词数量决定的。实验三采用不同语调模式和短语结构的话语，复制了语音词效应。最后，在实验4中，一个在线版本的句子生产任务提供了证据的音韵字作为首选的发音单位在连续语音的在线生产。我们的研究结果是一致的假设，即语音词是一个单位的语音编码的连接语音的处理。1997年学术出版社
Four experiments demonstrate effects of prosodic structure on speech production latencies. Experiments 1 to 3 exploit a modified version of the Sternberg et al. (1978, 1980) prepared speech production paradigm to look for evidence of the generation of prosodic structure during the final stages of sentence production. Experiment 1 provides evidence that prepared sentence production latency is a function of the number of phonological words that a sentence comprises when syntactic structure, number of lexical items, and number of syllables are held constant. Experiment 2 demonstrated that production latencies in Experiment 1 were indeed determined by prosodic structure rather than the number of content words that a sentence comprised. The phonological word effect was replicated in Experiment 3 using utterances with a different intonation pattern and phrasal structure. Finally, in Experiment 4, an on-line version of the sentence production task provides evidence for the phonological word as the preferred unit of articulation during the on-line production of continuous speech. Our findings are consistent with the hypothesis that the phonological word is a unit of processing during the phonological encoding of connected speech. q 1997 Academic Press
