目标.探讨声信号分型与气管食管（TE）发声者持续元音感知评价之间的关系以及信号分型在临床中的应用。两个评估独立分类1.75秒段的窄带声谱图根据声学信号类型和独立评估的记录相同的段的视觉模拟规模根据整体感知声学语音质量。研究了声信号类型与整体语音质量（连续量表和四点顺序量表）之间的关系，并分析了两种测量方法之间的一致性比例和可靠性。信号类型（I-IV）和顺序语音质量（四点量表）之间的协议是低的，但显着的，有一个显着的变量之间的线性关系。信号类型正确预测的语音质量数据不到一半。信号类型对连续语音质量评分有显著的主效应，信号类型I-IV、I-III和I-II之间的中值质量评分存在显著差异。信号分型可以用作TE语音的相同刺激的感知和声学评估的辅助手段，作为多维评估协议的一部分。目前形式的信号分类提供了有限的语音质量预测信息，并且在信号类型II和III与感知类别之间存在显著重叠。今后的工作应考虑是否可以改进目前的四种信号类型。
Objectives. To investigate the relationship between acoustic signal typing and perceptual evaluation of sustained vowels produced by tracheoesophageal (TE) speakers and the use of signal typing in the clinical setting.Methods. Two evaluators independently categorized 1.75-second segments of narrow-band spectrograms according to acoustic signal typing and independently evaluated the recording of the same segments on a visual analog scale according to overall perceptual acoustic voice quality. The relationship between acoustic signal typing and overall voice quality (as a continuous scale and as a four-point ordinal scale) was investigated and the proportion of inter-rater agreement as well as the reliability between the two measures is reported.Results. The agreement between signal type (I-IV) and ordinal voice quality (four-point scale) was low but significant, and there was a significant linear relationship between the variables. Signal type correctly predicted less than half of the voice quality data. There was a significant main effect of signal type on continuous voice quality scores with significant differences in median quality scores between signal types I-IV, I-III, and I-II.Conclusions. Signal typing can be used as an adjunct to perceptual and acoustic evaluation of the same stimuli for TE speech as part of a multidimensional evaluation protocol. Signal typing in its current form provides limited predictive information on voice quality, and there is significant overlap between signal types II and III and perceptual categories. Future work should consider whether the current four signal types could be refined.
