#1
Nicholas A May, Ronald C Scherer
Airflow during speech production is recorded using a pneumotachograph system wherein typically a mask is placed upon the face. Accurate measures of airflow require mask calibration and a complete seal of the mask rim to the face. Literature frequently cites mask rim leaks as causing flow measurement inaccuracies, but quantitative studies of the inaccuracies are needed. The purpose of this study was to determine the degree of inaccuracy of flow measurement using a Glottal Enterprises aerodynamic system for a variety of mask rim leak conditions...

OBJECTIVE AND HYPOTHESIS: Vocal effort in loud voice is produced with increased subglottal pressure during vowels and increased supraglottal pressure during consonants. In the paper, our main objective is to check whether it was supported by a parallel increase in the airflow resistance of the laryngeal articulator and of the supralaryngeal articulator, here the lips. STUDY DESIGN AND METHOD: For this comparison, our choice fell on the fricative consonants, as their production allows perfectly synchronous air pressure and airflow measurements...

BACKGROUND: A professional singer produced various vowels on a comfortable loudness and pitch in an inspiratory and expiratory phonation manner. The present study investigates the morphological differences and tries to find a link with the acoustical characteristics. OBJECTIVES/HYPOTHESIS: We hypothesize that features, constantly present over all vowels, characterize inhaling phonation and that the formant frequencies reflect the morphological findings. STUDY DESIGN: A prospective case study was carried out...

Hyaluronidase (HAase) injection into the vocal folds is an off-label use of an enzyme for liquefaction of hyaluronic acid (HA). HAase injection was performed in 14 cases in 13 patients. Office and operative injections of HAase were performed. The indications were five cases of overinjection of HA, six cases of Reinke edema and polypoid corditis, and three cases of acute vocal hemorrhage with early fusiform polyp formation. All the patients tolerated the HAase without complications. Significant voice improvements were noted between pre- and postinjection procedures as evaluated by a self-rating of voice by the Voice Handicap Index-10...

OBJECTIVES: Voice feminization therapy for male-to-female transgender women typically targets increasing fundamental frequency (F0). Increasing vowel formant frequencies (FFs) has also been proposed. To better understand formant conditions that shift listeners' perception of gender from male to "not-male," individual and combined vowel FFs were incrementally raised, whereas F0 was held constant at a gender-ambiguous level. METHODS: The study used a prospective, experimental group design...

REVIEW
Jing Kang, Austin Scholp, Jack J Jiang
Daily experience suggests that singing can energize us and even provide a physical workout. A growing amount of evidence has been presented to support anecdotal claims of the benefits of singing on health and well-being. Singing has been shown to be related to numerous physiological changes. The cardiorespiratory system is utilized during persistent singing training, resulting in enhanced respiratory muscles and an optimized breathing mode. In addition, singing can also cause changes in neurotransmitters and hormones, including the upregulation of oxytocin, immunoglobulin A, and endorphins, which improves immune function and increases feelings of happiness...
