A Study of Subharmonics in Connected Speech Material

摘要: Summary Subharmonics are often observed in running speech spectrograms that difficult to quantify. This study investigates the relationship between rough voice quality and presence—and amount—of subharmonics connected material a group of 35 male female speakers with pathology. Spectrum analysis was undertaken 145 pathologic voices, which 77 had speech. Only 34% 70 subjects under investigation developed both sustained phonations. All voices were judged as perceptually rough. The results this indicate do not differ examined acoustic characteristics except for modal fundamental frequency ( F 0 ). A small but significant difference roughness scores genders seems be caused by confounding perception factors related measurements number subharmonics. degree has irregularity index, percentage low estimates, and, lesser extent, power
