Collaborative Research: Establishing a Child Speech Fluency Database

儿童如何学习流畅地说话而不停顿、不重新开始、不出错或不遗漏（称为言语流畅性），很少受到研究关注。 一些表现出流利性困难的儿童，如晚说话和双语儿童，被误诊为语言障碍，如口吃。然而，不同的流利性问题需要不同类型的言语或语言治疗。 更好地理解典型的流利性发展和不同类型的流利性问题可以告知神经，语言和运动协调的要求，语音流畅性。 目前项目的目标是开发一个全面的数据库档案的音频和视频记录的儿童语音和相应的成绩单，可用于基础和临床研究的发展，在儿童的语言流畅性。 该项目通过使用CHILDES项目（www.childes.psy.cmu.edu）的现有数据（一个开放获取的儿童语音样本档案），研究了典型的、晚说话的和双语儿童在学龄前的流利性发展。另外，还将包括来自晚说话和双语儿童的语料库，以建立一个新的、更全面的“流利度银行”档案。 所有的语料库将被重新格式化，以验证和修改成绩单，索引语速，描述不流利的语言，并编码语音的语法特征。 将使用自动和半自动方法将录音和文字记录联系起来。由此产生的流畅性银行将成为一个重要的和独特的研究资源，为那些有兴趣在流利的发展，在两个典型的和典型的发展儿童。

How children learn to produce speech smoothly without stops, restarts, errors, or omissions (known as speech fluency), has received little research attention. Some children who exhibit fluency difficulties, such as later-talking and bilingual children, are misdiagnosed with speech disorders such as stuttering as a result. However different fluency issues require different types of speech or language therapy. A better understanding of typical fluency development and of different types of fluency problems can inform the neural, linguistic and motor coordination demands that underlie speech fluency. The goal of the current project is to develop a comprehensive database archive of audio and video recordings of child speech and their corresponding transcripts that can be used for both basic and clinical research on the development of speech fluency in children. This project examines fluency development during the preschool years in typical, late-talking, and bilingual children, by using existing data contributed to the CHILDES Project (www.childes.psy.cmu.edu), an open access archive of children's speech samples. Additional corpora from late-talking and bilingual children will also be included to establish a new, more comprehensive "Fluency Bank" archive. All corpora will be reformatted to validate and revise transcripts, index speech rate, characterize disfluencies, and code speech for grammatical features. Automatic and semi-automatic approaches will be used to link audio recordings and transcripts. The resulting Fluency Bank will become an important and unique research resource for those interested in fluency development in both typically and atypically developing children.
