由儿童产生的语音的特征在于高基频，这使得声道共振的测量以及因此的协同发音变得复杂。在这里，两个全频谱措施的协同发音进行验证，一个时间和频谱，这些挑战是不太敏感。使用这些措施，辅音-元音协同发音计算在一个大样本的4岁儿童的讲话。测量复制已知的舌coarticulatory的研究结果从文献中，表明这些声学措施的coarticulatory在所有年龄段的扬声器的效用。(C)2019年美国声学协会
Speech produced by children is characterized by a high fundamental frequency which complicates measurement of vocal tract resonances, and hence coarticulation. Here two whole-spectrum measures of coarticulation are validated, one temporal and one spectral, that are less sensitive to these challenges. Using these measures, consonant-vowel coarticulation is calculated in the speech of a large sample of 4-year-old children. The measurements replicate known lingual coarticulatory findings from the literature, demonstrating the utility of these acoustic measures of coarticulation in speakers of all ages.
