Describing Speech Usage in Daily Activities in Typical Adults
Journal of Voice (2016) Vol. 30, No. 1, pp. 42-52

"Speech usage" refers to what people want or need to do with their speech to meet communication demands in life roles. The purpose of this study was to contribute to validation of the Levels of Speech Usage scale by providing ...

Evaluation of Singer's Voice Quality by Means of Visual Pattern Recognition
Journal of Voice (2016) Vol. 30, No. 1, pp. 127.e21-127.e30

The article presents a description of the algorithm of singing voice quality assessment that uses selected methods from the field of digital image processing and recognition. It adopts the assumption that an audio signal with recorded vocal exercise can be ...

Relationship Between Subglottal Pressure and Sound Pressure Level in Untrained Voices
Journal of Voice (2016) Vol. 30, No. 1, pp. 15-20

Subglottal pressure (Ps) is strongly correlated with sound pressure level (SPL) and is easy to measure by means of commonly available equipment. The SPL/Ps ratio is strongly dependent on the efficiency of the phonatory apparatus and should be of great ...

The Flow and Pressure Relationships in Different Tubes Commonly Used for Semi-occluded Vocal Tract Exercises
Journal of Voice (2016) Vol. 30, No. 1, pp. 36-41

This experimental study investigated the back pressure (Pback) versus flow (U) relationship for 10 different tubes commonly used for semi-occluded vocal tract exercises, that is, eight straws of different lengths and diameters, a resonance tube, and a silicone tube similar ...

Vocal Effects in Military Students Submitted to an Intense Recruit Training: A Pilot Study
Journal of Voice (2016) Vol. 30, No. 1, pp. 61-69

This study aims at evaluating the vocal parameters of military officers before and after an Intense Recruit Training (IRT), consisting of a 48-hour exercise protocol involving high vocal demand combined with physical effort, lower body hydration levels, and fewer hours ...

Vocal Performance of Group Fitness Instructors Before and After Instruction: Changes in Acoustic Measures and Self-Ratings
Journal of Voice (2016) Vol. 30, No. 1, pp. 127.e1-127.e8

Objectives: (1) To quantify acute changes in acoustic parameters of the voices of group fitness instructors (GFIs) before and after exercise instruction. (2) To determine whether these changes are discernible perceptually by the instructor. Participants were six female GFIs, based ...

The First Application of the Two-Dimensional Scanning Videokymography in Excised Canine Larynx Model
Journal of Voice (2016) Vol. 30, No. 1, pp. 1-4

Evaluation of the vibratory pattern of vocal folds is of paramount importance to diagnose vocal fold disorders. Currently, laryngeal videokymography (VKG) and digital kymography from high-speed videolaryngoscopy are the available techniques for studying aperiodic vibrations of vocal folds. But VKG ...

Effect of Voice Onset Type on Vocal Attack Time
Journal of Voice (2016) Vol. 30, No. 1, pp. 11-14

Vocal attack time (VAT) is the time lag between the growth of sound pressure (SP) and electroglottographic (EGG) signals at vocal initiation. The characteristics of voice initiation are associated with issues of vocal hygiene, efficiency, and quality. Vocal onsets have ...

Relationship of Various Open Quotients With Acoustic Property, Phonation Types, Fundamental Frequency, and Intensity
Journal of Voice (2016) Vol. 30, No. 2, pp. 145-157

In the present study, we examined the relationship between various open quotients (Oqs) and phonation types, fundamental frequency (F0), and intensity by multivariate linear regression analysis (MVA) to determine which Oq best reflects vocal fold vibratory characteristics. Using high-speed digital ...

Validation of the Cepstral Spectral Index of Dysphonia (CSID) as a Screening Tool for Voice Disorders: Development of Clinical Cutoff Scores
Journal of Voice (2016) Vol. 30, No. 2, pp. 130-144

The purposes of this study were to (1) evaluate the performance of the Cepstral Spectral Index of Dysphonia (CSID--a multivariate estimate of dysphonia severity) as a potential screening tool for voice disorder identification and (2) identify potential clinical cutoff scores ...
