Physiological Observations and Synthesis of Subharmonic Voices
A subharmonic voice is a voice generated by subharmonic vibrations which include integer-multiple periodicity, such as periodic-double and periodic-triple. In this paper, various types of subharmonic voices were observed using high-speed digital imaging. A new laryngeal source model for synthesis of subharmonic voices were proposed based on the results of physiological observations. The proposed model consists of several modules, such as dumping function, and amplitude modulator. Parameters of the model were estimated by referring to the glottal area function, kymograph, and laryngotopography obtained by analysis of high-speed images. Synthesized sounds were scaled in similarity to diplophonia and the R (roughness) parameter of the GRBAS scale in listening tests. As a result, the proposed model was effective for synthesis of subharmonic voices, such as diplohphonia and rough voices.
