许多研究致力于检查非受损说话者的清晰语音与会话语音。这些先前研究的目的主要是为了帮助提高语音清晰度，以造福听力受损的听众。本研究的目的是检查帕金森病（PD）患者的会话和清晰语音之间的差异。12个人被记录生产会话和清晰的讲话。声学分析显示，PD患者使用了一些与非受损扬声器相同的清晰语音策略。具体而言，PD患者的清晰语音特征为清晰度降低、平均基频（F-o）增加和说话FoS. D增加。与会话相比。讨论探讨的可能性，个人与PD可能已经独立地应用一个清晰的语音策略的基础上，他们习惯性增加的百分比暂停值。学习结果：通过本活动，参与者将能够（1）描述非障碍个体所产生的清晰语音的特征，（2）描述帕金森病个体所产生的清晰会话语音的声学特征;（3）描述帕金森病患者在被要求发出清晰语音时使用的策略。(c)2004年爱思唯尔公司All rights reserved.
A number of studies have been devoted to the examination of clear versus conversational speech in non-impaired speakers. The purpose of these previous studies has been primarily to help increase speech intelligibility for the benefit of hearing-impaired listeners. The goal of the present study was to examine differences between conversational and clear speech in individuals with Parkinson disease (PD). Twelve individuals were recorded producing conversational and clear speech. Acoustic analysis revealed that individuals with PD used some of the same clear speech strategies used by non-impaired speakers. Specifically, clear speech in PD was characterized by decreased articulation rate, increased mean fundamental frequency (F-o), and increased speaking FoS.D. compared to conversational speech. The discussion examines the possibility that individuals with PD may have been independently applying a clear speech strategy based on their habitually increased percent pause values. Discussion also focuses on implications of the present findings to management of individuals with PD, and research implications.Learning outcomes: As a result of this activity, the participant will be able to (1) describe the characteristics of clear speech produced by non-disordered individuals, (2) describe the acoustic characteristics of clear and conversational speech produced by individuals with Parkinson disease; and (3) describe the strategies individuals with Parkinson disease use when asked to produce clear speech.
