Purpose: This study examines communicative congruence and communicative dysphoria in adults who deny having a voice disorder. Communicative congruence is the degree to which a person's communication is consistent with their sense of self/identity. Communicative dysphoria is the psychological entropy resulting from communicative incongruence. We…

Background; In the UK, there is increasing pressure on ear, nose and throat (ENT) clinicians and departments, which is anticipated to amplify in the coming months and years due to the coronavirus disease 2019 pandemic and other workforce pressures. In the context of a national drive to advance practice of Allied Health Professionals to address…

Purpose: Research suggests that abnormal levels of intrinsic laryngeal muscle (ILM) contraction is a potential causal factor in stress-induced voice disorders. This study seeks to characterize the ILM stress response in a cohort of vocally healthy women. Method: The authors used an unblinded, nonrandomized, repeated-measures design. Forty vocally…

Purpose: The purpose of this study is to introduce a chaos level test to evaluate linear and nonlinear voice type classification method performances under varying signal chaos conditions without subjective impression. Study Design: Voice signals were constructed with differing degrees of noise to model signal chaos. Within each noise power, 100…

Purpose: Phonations into a tube with the distal end either in the air or submerged in water are used for voice therapy. This study explores the effective mechanisms of these therapy methods. Method: The study applied a physical model complemented by calculations from a computational model, and the results were compared to those that have been…

Purpose: The larynx plays a role in swallowing, respiration, and voice production. All three functions change during ontogeny. We investigated ontogenetic shape changes using a mouse model to inform our understanding of how laryngeal form and function are integrated. We understand the characterization of developmental changes to larynx anatomy as…

Purpose: The purpose of this study was to obtain a more comprehensive understanding of the pathophysiology and impact on daily voice use of nonphonotraumatic vocal hyperfunction (NPVH). Method: An ambulatory voice monitor collected 1 week of data from 36 patients with NPVH and 36 vocally healthy matched controls. A subset of 11 patients with NPVH…

Purpose: The purpose of this study is to develop the Mandarin version of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) and evaluate its reliability compared with the Grade, Roughness, Breathiness, Asthenia, Strain (GRBAS). Method: The Mandarin version of the CAPE-V tool was translated from the validated English version with…

Background: To date, the immediate effects of a semi-occluded vocal tract (SOVT) configuration have been thoroughly demonstrated. However, it is not yet sufficiently confirmed whether a therapy programme (i.e. longer than one session) using SOVT exercises leads to an enhanced phonation and improved vocal quality. Aims: The aim of this study was to…

Purpose: The aims of this study were: (1) to quantify variability in voice production (as measured acoustically) within and across consecutive days in vocally healthy female speakers; (2) to identify which acoustic measures are sensitive to this variability; and (3) to identify participant characteristics related to such voice variability. Method:…

Purpose: The purpose of this study is to identify the extent to which various measurements of contacting parameters differ between children and adults during habitual range and overlap vocal frequency/intensity, using voice map-based assessment of noninvasive electroglottography (EGG). Method: EGG voice maps were analyzed from 26 adults (22-45…

Background: Traditional semi-occluded vocal tract exercises (SOVTEs) are restricted to single-phoneme tasks due to the semi-occlusion at the mouth, which hinders full articulation, continuous speech, and singing. Innovative SOVTEs should overcome this limitation by creating the semi-occlusion outside the oral cavity. Purpose: The purpose of this…

Purpose: Ambulatory voice biofeedback has the potential to significantly improve voice therapy effectiveness by targeting carryover of desired behaviors outside the therapy session (i.e., retention). This study applies motor learning concepts (reduced frequency and delayed, summary feedback) that demonstrate increased retention to ambulatory voice…

Purpose: Vocal roughness is often present in many voice disorders but the assessment of roughness mainly depends on the subjective auditory-perceptual evaluation and lacks acoustic correlates. This study aimed to apply the concept of roughness in general sound quality perception to vocal roughness assessment and to characterize the relationship…

Purpose: The purpose of this study was to determine the vocal fold structural and vibratory symmetries that are important to vocal function and voice quality in a simulated paramedian vocal fold paralysis. Method: A computational kinematic speech production model was used to simulate an exemplar "voice" on the basis of asymmetric…
