The purpose of this article is to quantify and describe stuttering-like disfluencies in speakers with acquired apraxia of speech (AOS), utilizing the Lidcombe Behavioural Data Language (LBDL). Additional purposes include measuring test-retest reliability and examining the effect of speech sample type on disfluency rates.
Two types of speech samples were elicited from 20 persons with AOS and aphasia: repetition of mono- and multisyllabic words from a protocol for assessing AOS (Duffy, 2013), and connected speech tasks (Nicholas & Brookshire, 1993). Sampling was repeated at 1 and 4 weeks following initial sampling. Stuttering-like disfluencies were coded using the LBDL, which is a taxonomy that focuses on motoric aspects of stuttering.
Disfluency rates ranged from 0% to 13.1% for the connected speech task and from 0% to 17% for the word repetition task. There was no significant effect of speech sampling time on disfluency rate in the connected speech task, but there was a significant effect of time for the word repetition task. There was no significant effect of speech sample type.
Speakers demonstrated both major types of stuttering-like disfluencies as categorized by the LBDL (fixed postures and repeated movements). Connected speech samples yielded more reliable tallies over repeated measurements. Suggestions are made for modifying the LBDL for use in AOS in order to further add to systematic descriptions of motoric disfluencies in this disorder.
本文旨在利用利兹康姆行为数据语言（LBDL）对获得性言语失用症（AOS）患者的口吃样不流畅性进行量化和描述。其他目的包括测量重测信度以及检验言语样本类型对不流畅率的影响。
从20名患有AOS和失语症的患者中收集了两种类型的言语样本：按照评估AOS的方案（达菲，2013年）重复单音节和多音节单词，以及连贯言语任务（尼古拉斯和布鲁克希尔，1993年）。在初次采样后的1周和4周重复采样。使用LBDL对口吃样不流畅性进行编码，LBDL是一种专注于口吃运动方面的分类法。
连贯言语任务的不流畅率在0%至13.1%之间，单词重复任务的不流畅率在0%至17%之间。在连贯言语任务中，言语采样时间对不流畅率没有显著影响，但在单词重复任务中时间有显著影响。言语样本类型没有显著影响。
患者表现出LBDL分类的两种主要口吃样不流畅性类型（固定姿势和重复动作）。连贯言语样本在重复测量中产生了更可靠的计数。建议对LBDL进行修改以用于AOS，以便进一步补充对该疾病运动性不流畅性的系统描述。
