Validation of the Cepstral Spectral Index of Dysphonia (CSID) as a Screening Tool for Voice Disorders: Development of Clinical Cutoff Scores

摘要

Objectives. The purposes of this study were to (1) evaluate the performance of the Cepstral Spectral Index of Dysphonia (CSID-a multivariate estimate of dysphonia severity) as a potential screening tool for voice disorder identification and (2) identify potential clinical cutoff scores to classify voice-disordered cases versus controls.
