Article Synopsis
- The study aimed to explore the link between low vitamin D levels, voice symptoms, and acoustic measurements in patients.
- It involved 38 participants divided into two groups: one with vitamin D deficiency and one with normal levels, assessing their vocal health through surveys and acoustic evaluations.
- The findings showed no significant differences in voice-related issues or acoustic parameters between those with low and normal vitamin D levels, suggesting the need for further research on this topic.
Objective: This study aimed to evaluate the association between facial width and length and fundamental frequency (F0) and habitual frequency.
Study Design: Prospective cross-sectional study.
Subjects: A total of 50 subjects (35 females;15 males) were included in this study.
Objective: To report the formant characteristics of English-speaking Lebanese men during steady prolongation of vowels /a/ and /i/.
Design: Cross-sectional study involving volunteer participants.
Participants: Fifty healthy English-speaking males with a mean age of 32 ± 4.
Objective: Investigate the association between formants frequencies and length and sagittal projection of the maxilla and mandible.
Study Design: Cross-sectional study.
Method: A total of 47 consecutive patients were recruited.
Objective: To report on the correlation between the length and projection of the upper and lower jaw and the fundamental frequency (F0).
Study Design: Prospective study.
Materials And Methods: A total of 45 healthy subjects were included in this study.
Objectives: This study examines the relationship between total body mass composition and vowel formant frequency and formant dispersion in men.
Methods: A total of 60 healthy male volunteers were recruited. Formant frequencies and dispersions of F1, F2, F3, and F4 for the vowels /ɑː/ and /iː/ were determined using spectrographic analysis.
Objective: To determine the effect of a Mediterranean tongue trill (Zalghouta) on estimated glottal closed quotient (CQ).
Material And Method: A total of 10 female subjects participated in this study. Vocal fold CQ was measured for both sustained vowel [a] and the tongue trill named Zlaghouta using electroglottography.
Speech perception in noise by monolingual, bilingual and trilingual listeners.
Int J Lang Commun Disord
May 2012
Background: There is strong evidence that bilinguals have a deficit in speech perception for their second language compared with monolingual speakers under unfavourable listening conditions (e.g., noise or reverberation), despite performing similarly to monolingual speakers under quiet conditions.

Material: A total of 40 male subjects were included in this study. Each subject underwent acoustic analysis using the Kay Elemetric VISI Pitch (Model 3300, KayPentax, Lincoln Park, NJ) and complete body mass analysis.
The aim of this prospective study is to assess the vocal changes in patients using nasal continuous positive airway pressure (CPAP). A total of 18 subjects using nasal CPAP were assessed by grading their voice perceptually as G0 for normal voice and G3 for severe hoarseness. Acoustic analysis was also performed and the following parameters were measured: fundamental frequency, habitual pitch, shimmer, relative average perturbation, voice turbulence index, and noise-to-harmonic ratio.

Material: A total of 13 Middle Eastern singers were enrolled in this study. There were 5 men and 8 women.
