The objective is to describe analysis methods that enable tracking vocal dysperiodicities in running speech. Vocal dysperiodicities here refer to deviations from strict periodicity in voiced speech sounds. Two methods are described. They respectively enable the sample-by-sample extraction of vocal noise from the speech signal or the isolation of speech cycles in voiced segments to quantify pert...

We conducted an AX-discrimination task to test for differences in perceived auditory similarity in monozygotic (MZ) and dizygotic (DZ) twin pairs and unrelated speakers. In addition, we performed acoustic analyses to find acoustic correlates that explain the differences in perceived similarity. Results indicate that unrelated speakers are significantly easier to distinguish than twins, but zygo...

conclusions significant difference in the fundamental frequency, jitter, shimmer, silence duration, friction duration, vocalization duration, and vocal cords contact quality index between the two groups was observed (p < 0.01). results the mean of fundamental frequency for the hearing loss children and the control group were 323.04 hz and 267.53 hz, jitter 10.05% and 1.52%, shimmer 17.24 and 5....

in order to comparison and determination of the best drought tolerance indices in sweet corn hybrids, an experiment was conducted using a randomized complete block design in split plot lay out with three replications at seed and plant improvement institute in karaj in 2006. three irrigation levels (irrigation after 75 as control, 100 and 125 millimeters cumulative evaporation from class a evapo...

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...

This study aimed to evaluate the effects of auditory-verbal rehabilitation on voice parameters after implantation with cochlear implants 2 and 5 months after rehabilitation and compare them with normal voice children (under 12 years of age). A perceptive and electroacoustic evaluation of voice was carried out through a digital analysis after implantation and rehabilitation. The study was pe...

background : a head and neck (h&n;) cancer severely affect the voice and compromises the patient’s vocal independence. the present study proposed to investigate the difference in the three vital components of voice the pitch, jitter and shimmer in h&n; cancer patients and compared it with age matched healthy volunteers. methods : the voice parameters were ascertained in the freshly diagnosed h&...

backround laryngopharyngeal reflux (lpr) is the backflow of stomach contents above upper esophageal sphincter, into the pharynx, larynx, and upper aerodigestive system. objectives in this study, effects of omeprazole over voice quality in muscle tension dysphonia with laryngopharyngeal reflux was ınvestigated. patients and methods nine patients, 7 males and 2 females, aged between 27-43 (mean a...
