Enhancement of electrolaryngeal speech by spectral subtraction, spectral compensation, and introduction of jitter and shimmer
An electrolarynx, a verbal communication aid used by laryngectomy patients, is a vibrator held against the neck tissue to provide excitation to the vocal tract, as a substitute to that provided by the glottal vibrations. Although the user can set the vibration level and pitch, a dynamic control of level, voicing, and pitch during speech production is not feasible. In addition to this basic limi...

15 صفحه اولUsing Jitter and Shimmer in speaker verification
Jitter and shimmer are measures of the fundamental frequency and amplitude cycle-to-cycle variations, respectively. Both features have been largely used for the description of pathological voices, and since they characterise some aspects concerning particular voices, they are expected to have a certain degree of speaker specificity. In the current work, jitter and shimmer are successfully used ...
متن کاملJitter and shimmer measurements for speaker recognition
Jitter and shimmer are measures of the cycle-to-cycle variations of fundamental frequency and amplitude, respectively, which have been largely used for the description of pathological voice quality. Since they characterise some aspects concerning particular voices, it is a priori expected to find differences in the values of jitter and shimmer among speakers. In this paper, several types of jit...
متن کاملJitter and shimmer differences between pathological voices of school children
A study was undertaken to determine differences between jitter and shimmer in voices of children with different syndromes. Voices of 60 children, both sexes, aged 7-12 years were analysed by EZ Voice Analysis Software (program for jitter and shimmer measuring). The main purpose of this paper has diagnostic background. Obtained results show, which acoustical indicators of pathological voice are ...
