来自声学和发音语音学的证据表明，儿童的共发音比成人多，但以前的工作主要集中在类型学同质样本中与音韵学的共发音实例化。协同发音与儿童语速的相互作用也被忽视了。协同发音和说话速度（持续时间）在发育过程中是如何相互作用的，这种相互作用在不同的形态环境中是否表现不同？为了回答这个问题，目前的研究测量了双语克丘亚-西班牙儿童（5-10岁）和成年人的语言模式。在两个词环境中，在语素内和跨语素边界测量协同发音和持续时间。不出所料，在两种形态环境中，成年人始终在较短的持续时间序列中进行更多的协同表达。然而，儿童的协同发音持续时间模式因形态环境而异。此外，儿童的语言模式，而不是成人的，对韵律长度很敏感：在音节较多的单词中，儿童发出的音越来越短。成人和儿童之间的差异可归因于成人更快的语速和克丘亚语的优势。
Evidence from acoustic and articulatory phonetics suggests that children coarticulate more than adults, but previous work has focused on the instantiation of coarticulation with phonology in a typologically homogeneous sample. The interplay of coarticulation with children’s speaking rate has also been ignored. How do coarticulation and speaking rate (duration) interact over the course of development, and does the interaction manifest differently across distinct morphological environments? To answer this, the current study measured the speech patterns of bilingual Quechua-Spanish children (5–10 years) and adults. Coarticulation and duration were measured in two word environments, within morphemes and across morpheme boundaries. Unsurprisingly, adults consistently coarticulated more in shorter duration sequences, in both morphological environments. The children’s coarticulation-duration patterns, however, varied by morphological environment. Additionally, the children’s speech patterns, but not the adults’, were sensitive to prosodic length: children produced increasingly shorter phones in words with more syllables. It is suggested that the differences between adults and children are attributable to adults’ faster speaking rate and increased dominance in Quechua.
