目的：探讨是否可以通过标记间语音变异性的多项测量来识别残留语音障碍(R-SSD)儿童的亚组。有R-SSD的儿童被记录在快速多音节图片命名任务和口头定向运动任务中。得到了基于转录和声学的令牌到令牌可变性的测量方法。还测量了发音准确性和语言技能的一般指标。语音可变性的基于转录的测量和声学测量之间以及声学测量本身之间的相关性很低。在一项指标上变数最大的儿童在其他指标上不一定有很大的变数。以转录为基础的可变性测量与语言技能有关。对语音变异性的测量并不能确定样本中的儿童始终处于高或低水平。数据不支持这样的概念，即在患有R-SSD的儿童中，可以可靠地识别基于语音可变性的明确亚组。高度可变的语音输出(通过基于转录的衡量标准来量化)与较低的语言技能之间的联系需要进一步探索。
To explore whether subgroups of children with residual speech sound disorders (R-SSDs) can be identified through multiple measures of token-to-token phonetic variability. Children with R-SSDs were recorded during a rapid multisyllabic picture naming task and an oral diadochokinetic task. Transcription-based and acoustic measures of token-to-token variability were derived. Articulation accuracy and general indices of language skills were also measured. Low correlations were observed between transcription-based and acoustic measures of phonetic variability, and among the acoustic measures themselves. Children who were the most variable on one measure were not necessarily highly variable on other measures. Transcription-based measures of variability were associated with language skills. Measures of phonetic variability did not identify children in the sample as consistently high or low. Data do not support the notion that clear subgroups based on phonetic variability can be reliably identified in children with R-SSDs. The link between highly variable phonetic output (quantified by transcription-based measures) and lower language skills requires further exploration.
