背景资料：言语失用症（AOS）和失语症伴音素性失语症之间的鉴别诊断具有挑战性，因为这两种疾病具有相似的言语特征。AOS的语音轮廓的量化是need.Aims：To classification的相对频率的声音失真的错误与失语症与无AOS的扬声器和独立listeners.Methods和程序之间的可靠性，以评估观察员之间的可靠性，这个度量：14名成年人与左半球病变被招募从一个连续的临床样本。根据多音节词产生率和感知明显的声音错误，他们被分配到可能的言语失用症（P-AOS）组或可能的失语症伴音素错语（P-APP）组。四个听众产生独立的语音transmittance从音频记录的电机语音评价。结果与结果：观察者间的信度对整体失真误差的频率是令人满意的（ICC=0.73，p
Background: The differential diagnosis between apraxia of speech (AOS) and aphasia with phonemic paraphasia is challenging because the disorders share similar speech characteristics. Quantification of the speech profile of AOS is needed.Aims: To characterise the relative frequency of sound distortion errors in speakers with aphasia with and without AOS and to evaluate inter-observer reliability for this metric among independent listeners.Methods & Procedures: Fourteen adults with left hemisphere lesions were recruited from a consecutive clinical sample. They were assigned to groups of probable apraxia of speech (P-AOS) or probable aphasia with phonemic paraphasia (P-APP), based on the multisyllabic word production rate and perceptually evident sound errors. Four listeners generated independent phonetic transcriptions from an audio-recorded motor speech evaluation. The percentage of distorted segments and inter-observer reliability were calculated.Outcomes & Results: Inter-observer reliability was satisfactory for frequency of the overall distortion errors (ICC=0.73, p
