In speech analysis, the information about the glottal source is obtained from speech by using glottal inverse filtering (GIF). The accuracy of state-of-the-art GIF methods is sufficiently high when the input speech signal is of high-quality (i.e., with little noise or reverberation). However, in realistic conditions, particularly when GIF is computed from coded telephone speech, the accuracy of...

A model has been developed which is designed to preserve some of the naturalness that is usually lost in speech synthesis. A parametrized function is used to produce an approximation to the cross-sectional rea through the glottis. A circuit model of the subglottal and glottal system is used with the supraglottal pressure to generate the glottal volume velocity. The tract used to obtain the supr...

In the source-filter theory, the complete closure of the glottis is assumed as a glottal boundary condition. However, such assumption of glottal closure in the source-filter theory is not strictly satisfied in actual utterance. Therefore, it is considered that acoustic features of the glottis and the subglottal region may affect vocal tract formants. In this study, we investigated how differenc...

This paper describes the implementation of a new parametric model of the glottal geometry aimed at improving male and female speech synthesis in the framework of articulatory analysis synthesis. The model represents glottal geometry in terms of inlet and outlet area waveforms and is controlled by parameters that are tightly coupled to physiology, such as vocal fold abduction. It is embedded in ...

In this paper, a novel stereo-endoscopic high-speed digital imaging system and a method to estimate the glottal area function are proposed. Glottal length, width, and area of one female participant were estimated in three different fundamental frequencies (F0s).

background: compressive neuropathy of median nerve is relatively common but development of an hourglass like constriction is a rare phenomenon. the purpose of this study is to show morphologic changes of median nerve in advances carpal tunnel syndrome. methods: eighty patients with thenar atrophy, anesthesia and paresthesia of first, second and third finger and severe changes of emg‑ncv were ch...
