Acoustic and perceptual analysis of vocal tremor
The objective is to present a method to analyze vocal tremor in sustained speech sounds and compare the results with a perceptual scoring of the degree of tremor. The vocal cycle lengths are tracked by salience analysis and dynamic programming. The cycle length time series is then split into three components by empirical mode decomposition: jitter, tremor and trend. Tremor cues are obtained via...
متن کاملAcoustic and perceptual analysis of vocal registers in children
According to Hirano, Kurita and Nakashima (1983) the vocal fold structure changes continuously from earliest childhood to late adolescence. During pubert), the elastic fibers are differentiated from the deeper collagenous fibers. These changes can be assumed to affect the vocal register function. The pitches at which register transitions occurred were identified perceptually in recordings of 15...
متن کاملAcoustic analysis of vocal fatigue in professional voice users
vocal fatigue is a voice symptom which is frequently reported by professional voice users. teachers, singers, actors and other professions that require prolonged voice use are especially at-risk group. the vocal fatigue results in auditory perceptual and acoustic changes in the voice signal and can lead to serious pathological conditions. the present study has examined acoustic manifestations o...
متن کاملAuto-meshing algorithm for acoustic analysis of vocal tract
We propose a new method for an auto-meshing algorithm for an acoustic analysis of the vocal tract using the Finite Element Method (FEM). In our algorithm, the domain of the 3 dimensional figure of the vocal tract is decomposed into two domains; one is a surface domain and the other is an inner domain in order to employ the overlapping domain decomposition method. The meshing of surface blocks c...
متن کاملThe Vocal Expression of Emotion: An Acoustic Analysis of Anxiety
During conversations, speakers are assumed to provide information about their emotional state. This study is a systematic investigation of the voice characteristics of the emotion of anxiety. For this purpose speech samples of 63 subjects were collected in a situation which induced mild anxiety. On the basis of the acoustic measurements it appears that anxiety affects vocal parameters and showe...
