摘要
Gravelin等人(2023)开发了一种以系统功能语言学(SFL)为基础的分割程序,用于分析即兴语音样本。本研究的目的是研究该系统应用于10名帕金森病(PD)患者的样本时的可靠性、实用性和应用。两名专家分析师和一名临床分析师利用基于sfl的分割程序来识别子句和子句复合物。我们计算了每个分析师和一对分析师的内部和内部可靠性。我们还测量了语音声学,包括持续时间,复杂间停顿时间和每个子句复合的语速。分析人员内部和之间的SFL分割程序的内部和内部可靠性都显示出高的一致性,显着大于机会(κ = 0.661-0.855; p
Reliability of a procedure for segmenting extemporaneous speech produced by speakers with Parkinson disease.
Gravelin et al. (2023) developed a segmentation procedure informed by Systemic Functional Linguistics (SFL) for parsing extemporaneous speech samples. The purpose of the current study is to investigate the reliability, utility, and application of this system when it is applied to samples produced by 10 participants with Parkinson Disease (PD). Two expert analysts and one clinician analyst utilised an SFL-based segmentation procedure to identify clauses and clause complexes. We calculated intra- and inter-rater reliability for each analyst and pair of analysts. We also measured speech acoustics, including duration, inter-complex pause durations, and speech rate for each clause complex. Both intra- and inter-rater reliability for SFL segmentation procedures within and between analysts revealed high percent agreement that was significantly greater than chance (κ = 0.661-0.855; p < 0.001) for speakers with PD. Acoustic analyses revealed expected variation in number and duration of spoken syllables of clause complexes between and within speakers. The clause-focused segmentation approach operationalised in Gravelin et al. (2023) and the current study is a reliable method for segmenting extemporaneous speech produced by individuals with PD. Moreover, this method allows for acoustic examination of speech and prosody production.
