Acoustic screening for laryngeal cancer.
An acoustic screening method for indicating the possible presence of laryngeal cancer was investigated. Three acoustic parameters, comprising perturbations in pitch-period and peak-amplitude sequences, 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 groups were performed with voice samples taken from 64 normal control subjects and 57 patients with laryngeal cancer. Experiments were also carried out to test the perceptual significance of the three parameters. From the results, we have been able to conclude that their combined use will enable us to build an acoustic screening system for laryngeal cancer.
