We investigated phonetic imitation of coarticulatory vowel nasality using an adapted shadowing paradigm in which participants produced a printed word (target) after hearing a different word (prime). Two versions of primes with nasal codas were used: primes with a natural degree of vowel nasality and hypernasalized primes. The version of the prime participants heard varied, whether consistent with their past experience with nasality from the talker or inconsistent, and the duration of delay between prime and target. People spontaneously modify coarticulatory nasality to resemble that demonstrated in the prime they were exposed to. Furthermore, this imitation also reflects the degree of nasality demonstrated by overall experience with the speaker's vowels. The influence of past experience on imitation increases with increased delay between prime and target. Imitation of another speaker appears to involve tracking general articulatory properties about the speaker, and not solely what was specific to the most recent experience.
我们使用一种改编的跟读范式，研究了协同发音元音鼻音的语音模仿，在该范式中，参与者在听到一个不同的单词（启动词）后说出一个印刷单词（目标词）。使用了两种带有鼻韵尾的启动词版本：具有自然程度元音鼻音的启动词和过度鼻音化的启动词。参与者听到的启动词版本各不相同，无论与他们过去对说话者鼻音的体验一致与否，以及启动词和目标词之间的延迟持续时间。人们会自发地改变协同发音的鼻音，使其与他们接触到的启动词中所展示的鼻音相似。此外，这种模仿还反映了通过对说话者元音的整体体验所展示的鼻音程度。过去经验对模仿的影响会随着启动词和目标词之间延迟的增加而增强。对另一个说话者的模仿似乎涉及追踪关于该说话者的一般发音特性，而不仅仅是最近体验中特有的内容。
