To determine if Parkinson's disease (PD) patients have increasing difficulty as speech tasks become longer or more complex, the timing and accuracy of isolated syllables and repeated sequences of syllables were studied. Acoustic measures of PD patient's syllables were similarly impaired relative to normal controls for both isolated and repeated syllable sequences. Listeners' identification scores were equally high for both types of productions. Unlike previous studies of other types of movements in PD, speech accuracy and timing does not deteriorate as items become longer or more complex.
为了确定帕金森病（PD）患者在言语任务变长或变得更复杂时是否会有越来越大的困难，研究了孤立音节和重复音节序列的时间和准确性。对于孤立音节序列和重复音节序列，PD患者音节的声学指标相对于正常对照组同样受损。对于这两种类型的发音，听众的识别分数同样高。与之前对PD患者其他类型运动的研究不同，随着项目变长或变得更复杂，言语准确性和时间控制并不会恶化。
