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. This deficit persists for speakers highly proficient in their(More)
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:(More)
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. Frequencies and means (±standard(More)
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. RESULTS The mean(More)
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. Craniofacial measures included; maxillary length (ANS-PNS), mandibular length (Co-Gn), relationship between maxilla and mandible(More)
PURPOSE This work was conducted to describe the formant frequencies in a group of Middle Eastern singers and to look for the presence of the singer's formant described in operatic singers. MATERIAL A total of 13 Middle Eastern singers were enrolled in this study. There were 5 men and 8 women. METHOD Descriptive analysis was performed to report the(More)
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. METHODS Lateral and posteroanterior cephalometric measurements included: facial(More)
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. The facial skeletal measurements included: SNA, SNB, ANB, angles that reflect the position of the maxilla(More)
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 ± 4.027 years and a range of 42 years (18-60). MATERIALS AND METHODS A total of 50(More)
Purpose The purpose of this article was to investigate the relationship between low level of vitamin D, phonatory symptoms, and acoustic findings. Method A total of 38 subjects presenting to the endocrinology clinic were enrolled in 2 groups: 19 with vitamin D deficiency who were not on treatment, and 19 with normal vitamin D level who were on treatment.(More)
