Abstract
The goal of clinical speech analysis is to describe abnormalities in speech production that affect a speaker's intelligibility. Landmark analysis identifies abrupt changes in a speech signal and classifies them according to their acoustic profiles. These acoustic markers, called landmarks, may help describe intelligibility deficits in disordered speech. As a first step toward clinical application of landmark analysis, the present study describes expression of landmarks in normal speech. Results of the study revealed that syllabic, glottal, and burst landmarks consist of 94% of all landmarks, and suggest the effect of gender needs to be considered for the analysis.
摘要
临床语音分析的目标是描述影响说话者可懂度的语音产生异常情况。地标分析识别语音信号中的突变，并根据其声学特征对其进行分类。这些被称为地标的声学标记可能有助于描述言语障碍中的可懂度缺陷。作为地标分析临床应用的第一步，本研究描述了正常语音中地标的表现。研究结果显示，音节、声门和爆发地标占所有地标的94%，并表明在分析时需要考虑性别的影响。
