以往的研究表明，正常人和失语症患者的多音节词的重音元音持续时间比单音节词短。然而，失语症患者的重音元音持续时间缩短的幅度和模式在不同的研究中并不一致。我们假设，这种不一致性可以解释基于不同的相对措施的持续时间减少，语音样本获得10名失语症发言人与AOS，10名失语症发言人没有AOS，和10名正常对照。正如所预测的那样，使用两种不同的相对度量，导致不同的元音减少模式，这两个帐篷与以前的报告。研究结果进一步表明，生产的多音节词是特别征税AOS和与其他失语症和正常的扬声器相比，说话率大幅下降。(C)2001年，爱思唯尔科学。
Previous research has established that the duration of stressed word stein vowels is shorter in polysyllabic words than in monosyllabic words for normal speakers and for speakers with aphasia and apraxia of speech (AOS), However, the results are inconsistent across studies with regard to the magnitude and pattern Of the duration reduction for apraxic speakers. We hypothesized that this inconsistency may be explained based on different relative measures of duration reduction, A speech sample was obtained from 10 aphasic speakers with AOS, 10 aphasic speakers without AOS, and 10 normal controls. As predicted, the use of two different relative measure,.; resulted in different vowel reduction patterns, both of which were tent with previous reports. The results further indicate that the production of polysyllabic words is particularly taxing in AOS and is associated with a substantial reduction of speaking rate compared to other aphasic and normal speakers.
