| Abstract: | An acoustic screening method for indicating the possible presenceof laryngeal cancer was investigated. Three acoustic parameters,comprising perturbations in pitch-period and peak-amplitudesequences, and vocal noise, were measured from a sustained vowel,e, spoken by the subjects taking part in the investigation.Experiments to discriminate between normal and cancer groupswere performed with voice samples taken from 64 normal controlsubjects and 57 patients with laryngeal cancer. Experimentswere also carried out to test the perceptual significance ofthe three parameters. From the results, we have been able toconclude that their combined use will enable us to build anacoustic screening system for laryngeal cancer. |
