Age-Related Differences in Acoustic Voice Quality and Mandarin Lexical-Tone Production Among Mandarin-Speaking Women.

OBJECTIVES: To investigate whether there are age differences in acoustic voice quality, Mandarin lexical-tone production, and within-speaker tone stability in Mandarin-speaking healthy women. METHODS: A total of 220 women aged 18-84 years participated in a cross-sectional study and completed sustained vowel, maximum phonation time, connected speech, and Mandarin lexical-tone tasks. Smoothed cepstral peak prominence (CPPS), F0, jitter, shimmer, harmonics-to-noise ratio, corrected spectral voice-source measures, speech timing, AVQIv3-M, and time-normalized F0 contours for Tones 1-4 were analyze…

Validation of the TruBlue Light Laser for Laryngeal Somatosensory and Perturbation Testing.

OBJECTIVES: Clinical assessment of laryngeal somatosensation is limited by the lack of precise tools to directly stimulate the larynx and qu … mucosa. Single subablative pulses (1-10 W, 30 ms) were applied during quiet breathing or sustained phonation to determine perceptual and reflexive sensory thresholds, discrimination acuity, and laryngeal perturbation responses. Acoustic recordings during perturbations were analyzed in Praat using custom software to extract continuous fundamental frequency …

Each patient performed 6 vocal tasks: phonation A, phonation I, reading, monologue, fast syllables repetitions. The DA extracted 23 speech features as age-, gender-, and education-adjusted z-scores against healthy controls. A principal component analysis was conducted. Correlations between the co …

The effects of vocal tract constrictions on aerodynamic measures in a synthetic vocal fold model.

According to nonlinear source-filter theory, as the strength of the coupling between the source and filter increases, typically by a decreas … tion cross-sectional areas were examined at two locations (i.e., at the epilarynx and lip regions). Phonation threshold pressure and flow were measured at phonation onset and offset using four M5-CONV vocal fold models. Results indicated that both constriction magnitude and location are relevant factors in determining glottal aerodynamics. In general, a nar …

Sedation, sleep-promotion, and non-verbal and verbal communication techniques in critically ill intubated or tracheostomized patients: results of a survey.

BACKGROUND: The aim of this survey was to describe, on a patient basis, the current practice of sedation, pharmacologic and non-pharmacologi … ng masks were rarely used (< 7%). In half of the participating intensive care units a technique for phonation was used in the tracheostomized patients. CONCLUSIONS: The overall rate of moderate and deep sedation appears high, particularly in oro-tracheally intubated patients. There is no uniform sleep management and ear plugs and sleeping masks are only ra …

The effect of nasal septum deviation on voice aging.

PURPOSE: The aging process of the voice differs among individuals, and the factors that affect age-related changes in voice are not well-defined. In this study, we investigated the difference between older people with nasal septum deviation (NSD) and older people without NSD in terms of degree of aging voice using objective and subjective voice assessment tools. METHODS: The study included 94 patients (47 women, 47 men) aged >65 years. Nasal septum deviation was determined in 45 patients (NSD group), and 49 patients had no nasal pathology (control group). Maximum phonation time (MPT), GRBAS s…

Auditory Feedback Control of Vocal Pitch in Spasmodic Dysphonia.

OBJECTIVES/HYPOTHESIS: Hearing plays an important role in the maintenance of vocal control in normal individuals. In patients with spasmodic dysphonia (SD), however, the ability to maintain sustained control of phonation is impaired. The origins of SD are unknown, and it is unclear whether auditory feedback-dependent vocal control is compromised in these patients. STUDY DESIGN: Prospective case-control study. METHODS: We tested 15 SD patients and 11 age-matched controls. Voice recordings were performed while subjects repeated the vowel /e/ and auditory feedback of their vocal sounds was alte…

Objective: To investigate the efficacy of type I thyroplasty with Montgomery prosthesis implantation for the treatment of unilateral vocal f … ed GRBAS auditory perception assessment, acoustic analysis such as Jitter, Shimmer, NHR and maximum phonation time (MPT). Results: Postoperative videostroboscopy observed the displacement of paralyzed vocal fold to the midline in 44 cases as well as significantly reduced glottic fissures during phonation. In the other 2 cases, glottic fissure did not reduce …

Analyses of Sustained Vowels in Down Syndrome (DS): A Case Study Using Spectrograms and Perturbation Data to Investigate Voice Quality in Four Adults With DS.

OBJECTIVES: Automatic acoustic measures of voice quality in people with Down syndrome (DS) do not reliably reflect perceived voice qualities … en the four participants. CONCLUSIONS: Although the acoustic data do not clearly indicate atypical phonation, diplophonia and subharmonics reflect nonmodal phonation. The findings suggest that these may contribute to different perceived voice qualities in the study group and that these qualities may result from intermittent involvement of supraglottal stru …
