Objective Voice Analysis of Iranian Speakers with Normal Voices
Journal of Voice, 2010 Objective measurements in general and acoustic measurements in particular have become a substantial aspect of voice assessment during the last few decades and studies have established that normative data is necessary for acoustic analysis. Voice acoustic analysis including fundamental frequency (F(0)), jitter, shimmer, harmonics-to-noise ratio (HNR ...

Even though recent investigations have used multiparametric protocol, the set of robust parameters in determining the effects of vocal fatigue and voice rest in teachers is not clear. The first objective of the study was to document the impact of prolonged voice use and voice rest on the subjective and objective voice parameters among Indian secondary ...

Predictability analysis of voice signals
IEEE Engineering in Medicine and Biology Magazine, 2009This paper, proposes a method of voice signal analysis based on predictability measures. The objective is the differentiation of three groups of signals: healthy, nodules on the vocal folds, and Reinke's edema. This method is a slight reformulation of a measure called predictive power (PP) that uses the relative entropy between the signal and its ...

A Meta-Analysis of the Association Between the Voice Handicap Index and Objective Voice Analysis
Journal of Speech, Language, and Hearing Research, 2020Purpose Dysphonia can be evaluated by both patient-reported quality of life instruments and objective acoustic and aerodynamic analyses. However, less is known about the association between the two metrics. The goal of this study was to perform a meta-analysis of the correlation of the Voice Handicap Index (VHI-30) with the ...

Voice analysis for detection of deception
2016 11th International Conference on Knowledge, Information and Creativity Support Systems (KICSS), 2016Human voice can signal the psychological state of an individual. Be it emotional, physical, intentional or unconscious, voice reveals the internal state of the speaker. Therefore, the main aim of the present study is to identify which voice parameter could be used as a reliable indicator of stress due to deception.

Voice Analysis and Behavior Pattern
JAMA: The Journal of the American Medical Association, 1969To the Editor:— I should like to comment on the article "Voice Analysis for Detection of Behavior Pattern" by Friedman, et al (208:828, 1969). The usefulness of the proposed test in classifying subjects rests on the fact that the test procedure gave high results (greater than mean + 2 SD for the type B subjects) in 84% of type A subjects.

Acoustical analysis for voice disorders
ICASSP '76. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005Glottal sound waveforms were derived by an inverse filtering method from sustained vowels uttered by 217 patients of laryngeal diseases and by 20 normal speakers. Various parameters which indicate individual characteristics were extracted from autocorrelation function, correlograms of time series of fundamental period and peak amplitude in each ...

The nonverbal content of speech carries information about the physiological and psychological condition of the speaker. Psychological stress is a pathological element of this condition, of which the cause is accepted to be “workload”. Objective, quantifiable correlates of stress are searched for by means of measuring the acoustic modifications of the ...

The authors propose a software system for pathological voice analysis and screening of laryngeal diseases that has the following properties: a) The analysis is totally noninvasive-the microphone is about 30 cm from the patient's mouth, and contact microphones or laryngophones are not used. b) The system is built around a low-cost personal computer (PC).
