Acoustical and clinical assessment of voice quality with laryngeal pathology

Abstract

Acoustical waveform studies have been conducted since a long time, and results have been reported by many experts, but it is still an interesting matter for clinicians to explore. Clinicians are seeking for a practical automatic and non-invasive technique for clinical purposes. Our study on voice perturbation covered a 3 years period data, from January 1990 until December 1992, including 672 voice data consisting of various diseases, which cause vocal changes. The results revealed that some aims of voice analysis were achieved, although the main target is still a little bit far.
