言语产生障碍可能伴随着言语感觉反馈的异常处理。在这里，我们介绍了一个半自动化的分析，旨在评估扬声器使用自然的在线反馈，以减少语音的声学变化的程度。由于失语症的产生缺陷被假设源于感觉运动整合的问题，我们调查了失语症（PWA）患者是否可以在线纠正他们的语音声学。慢性期的八个PWA产生了三个单音节词的200次重复。在音节内的多个时间窗口中测量每个元音的共振峰变异性，并量化从元音起始到中点的共振峰变异性的减少。PWA显着降低声学变异的过程中的音节，提供证据的在线反馈校正机制。这种校正共振峰运动的幅度超过了过去的测量控制参与者。元音中心的行为表明，纠错能力至少部分地幸免于失语症的扬声器，并可能依赖于弥补前馈赤字，使话语回到正轨。这些概念数据的证据表明，这种分析技术的潜力，阐明的机制，语音产生障碍的基础。
Disorders of speech production may be accompanied by abnormal processing of speech sensory feedback. Here, we introduce a semi-automated analysis designed to assess the degree to which speakers use natural online feedback to decrease acoustic variability in spoken words. Because production deficits in aphasia have been hypothesised to stem from problems with sensorimotor integration, we investigated whether persons with aphasia (PWA) can correct their speech acoustics online. Eight PWA in the chronic stage produced 200 repetitions each of three monosyllabic words. Formant variability was measured for each vowel in multiple time windows within the syllable, and the reduction in formant variability from vowel onset to midpoint was quantified. PWA significantly decreased acoustic variability over the course of the syllable, providing evidence of online feedback correction mechanisms. The magnitude of this corrective formant movement exceeded past measurements in control participants. Vowel centering behavior suggests that error correction abilities are at least partially spared in speakers with aphasia, and may be relied upon to compensate for feedforward deficits by bringing utterances back on track. These proof of concept data show the potential of this analysis technique to elucidate the mechanisms underlying disorders of speech production.
