声学方法已经发展到可以通过对语音子系统（例如发声、鼻腔共鸣、元音发音、辅音发音、语调和节奏）的参数评估来构建运动性言语障碍的声学类型。该分析的结果可以根据语音的全局功能（例如语音质量、清晰度和韵律）来解释。本文回顾了一些研究，这些研究表明，特定的声学分析对于构建构音障碍和言语失用症的声学特征的总体目标已经证明或具有潜在的价值。几种不同的声学测量与运动性言语障碍的研究相关，并且这些测量越来越受到规范数据和临床应用指南的支持。针对各种特定的神经系统疾病或知觉类型的障碍讨论了这些应用的示例。声学研究对于运动性言语障碍的研究很有用，最近的进展表明参数分析。
Acoustic methods have progressed to the point that an acoustic typology of the motor speech disorders can be constructed from a parametric assessment of the speech subsystems (e.g., phonation, nasal resonance, vowel articulation, consonant articulation, intonation, and rhythm). The results of this analysis can be interpreted in respect to global functions in speech (e.g., voice quality, intelligibility, and prosody). This paper reviews studies showing that specific acoustic analyses have demonstrated or potential value toward the overall goal of constructing acoustic profiles of dysarthria and apraxia of speech. Several different acoustic measures are relevant to the study of the motor speech disorders, and these are increasingly supported by normative data and by guidelines for clinical application, Examples of these applications are discussed for a variety of specific neurologic diseases or perceptual types of disorder. Acoustic studies are useful in the study of motor speech disorders and recent progress points to a parametric analysis.
