Intelligibility Across a Reading Passage: The Effect of Dysarthria and Cued Speaking Styles

Objective: Reading a passage out loud is a commonly used task in the perceptual assessment of dysarthria. The extent to which perceptual characteristics remain unchanged or stable over the time course of a passage is largely unknown. This study investigated crowdsourced visual analogue scale (VAS) judgments of intelligibility across a reading passage as a function of cued speaking styles commonly used in treatment to maximize intelligibility. Patients and Method: The Hunter passage was read aloud in habitual, slow, loud, and clear speaking styles by 16 speakers with Parkinson's disease (PD), 30 speakers with multiple sclerosis (MS), and 32 control speakers. VAS judgments of intelligibility from three fragments representing the beginning, middle, and end of the reading passage were obtained from 540 crowdsourced online listeners. Results: Overall passage intelligibility was reduced for the two clinical groups relative to the control group. All speaker groups exhibited intelligibility variation across the reading passage, with trends of increased intelligibility toward the end of the reading passage. For control speakers and speakers with PD, patterns of intelligibility variation across passage reading did not differ with speaking style. For the MS group, intelligibility variation across the passage was dependent on speaking style. Conclusions: The presence of intelligibility variation within a reading passage warrants careful selection of speech materials in research and clinical practice. Results further indicate that the crowdsourced VAS rating paradigm is useful to document intelligibility in a reading passage for different cued speaking styles commonly used in treatment for dysarthria.

Effect of Intensive Voice Therapy in a Patient With Multiple System Atrophy

Introduction: Multiple System Atrophy (MSA) is a degenerative neurogenic disorder characterized by multiple symptoms affecting the movements and autonomic nervous system. It reduces the function of various types of nerve cells in the brain and spinal cord. MSA causes some movement disorders such as dysarthria that is one of the most common symptoms in these patients. The first neurological sign that sometimes progresses is the complete inability to produce speech. This study aimed to evaluate the effect of an intensive voice therapy based on the principles of Lee Silverman Voice Therapy (LSVT) on improving acoustic features, intelligibility, and quality of life index of the patients with MSA. Materials and Methods: The patient was a 57-year-old woman with MSA disorder. Acoustic assessments of voice, intelligibility, and voice handicap index were performed before and after the treatment program according to LSVT principles. Results: Acoustic values such as intensity, frequency, and harmonic to noise ratio increased, and jitter and shimmer parameters decreased. Amount of perception of intelligibility increased. A significant decrease in the scores of the quality of life index related to voice handicap was observed. Conclusion: After treatment by intensive voice therapy, the acoustic assessment revealed improvement in all voice parameters. The perceptual assessment showed improved intelligibility and increased the patient’s quality of life. Intensive voice therapy based on LSVT principles effectively improves the acoustic features, which subsequently cause intelligibility to be more comprehensible. It generally improves verbal communication, which has a positive effect on the patient’s quality of life.

Impact of subclinical mental disorders of voice function and quality of life in voice-speaking professions during the COVID-2019 pandemic

Objective: To investigate the risk of mental distress during the COVID-19 pandemic in individuals of the voice-speech professions and the possibility of its impact on voice function and quality of life. Materials and Methods: The study involved 33 people of voice-speech professions who were treated at the University Clinic of Zaporizhzhia State Medical University in 2020. The presence of mental disorders was determined by questionnaires using the hospital anxiety and depression scale (HADS). The patients were divided into 2 groups, depending on the absence and presence of significantly expressed symptoms. A specialized phoniatric examination using functional loads (measuring the time of maximum phonation (PMF), perceptual assessment of the voice according to the GRBAS scale), videostroboscopy of the larynx were carried out. The assessment of the mental impact of voice disorders on the quality of life was carried out according to the Voice Handicap Index (VHI) questionnaire. The statistical significance of the comparative indicators and the connection of their changes were established using the Spearman's rank correlation coefficient. Results: It was found that among the surveyed 33 people, 22 patients (group 1) had subclinical anxiety and depression, and 11 (group 2) had no significant symptoms. Patients with subclinically severe mental disorders (n = 22) showed a significant increase in the emotional indicator by 85.37% (p≤0.01). A high positive relationship was found between subclinical levels of anxiety and depression and disturbances in the phonatory cycle of the larynx. When conducting a Spearman correlation analysis between the data of perceptual assessment of the voice according to the GRBAS system, data of video stroboscopy of the larynx, indicators of anxiety and depression, and the results of the VHI questionnaire, a positive relationship of a high degree was established between the level of anxiety and vibratory insufficiency of the vocal folds (rs=0.95; p≤0.05), negative with the Navy (rs=-0.59; p≤0.05), as well as physical (rs=0.75; p≤0.05) and emotional (rs=0.79; p≤0.05) components of average quality of life. The data obtained indicate a significant effect of subclinical disorders of the mental state on impaired voice function and the emotional component of the quality of life in persons of vocal-speech professions. Conclusions: Screening of mental health in persons of voice-speech professions together with a baseline assessment of voice function and quality of life are important steps for monitoring potential voice disorders and the formation of risk groups in order to carry out preventive and therapeutic measures for voice disorders.

Rehabilitation Management of Post Palatoplasty in Adolescent: Case Report

The objective of this study is to report comprehensive physical medicine and rehabilitation management of post-palatoplasty in an adolescent patient. The cleft palate repair is usually done in the first year of life in order to gain optimal speech function. To achieve normal communication development, normal hearing, normal oral and pharyngeal structures, adequate stimulation, and reinforcement from the environment for communication efforts are needed. Patient was assessed comprehensively using The International Classification of Functioning, Disability and Health (ICF) and by perceptual assessment for speech. The results showed that after one month intervention, the perceptions of hypernasality in plosive /b/ and affricates /c/ were found reduced significantly. There was improvement in articulation after one month of intervention.

Improved Estimation of Parkinsonian Vowel Quality through Acoustic Feature Assimilation

This paper investigated the performance of a number of acoustic measures, both individually and in combination, in predicting the perceived quality of sustained vowels produced by people impaired with Parkinson’s disease (PD). Sustained vowel recordings were collected from 51 PD patients before and after the administration of the Levodopa medication. Subjective ratings of the overall vowel quality were garnered using a visual analog scale. These ratings served to benchmark the effectiveness of the acoustic measures. Acoustic predictors of the perceived vowel quality included the harmonics-to-noise ratio (HNR), smoothed cepstral peak prominence (CPP), recurrence period density entropy (RPDE), Gammatone frequency cepstral coefficients (GFCCs), linear prediction (LP) coefficients and their variants, and modulation spectrogram features. Linear regression (LR) and support vector regression (SVR) models were employed to assimilate multiple features. Different feature dimensionality reduction methods were investigated to avoid model overfitting and enhance the prediction capabilities for the test dataset. Results showed that the RPDE measure performed the best among all individual features, while a regression model incorporating a subset of features produced the best overall correlation of 0.80 between the predicted and actual vowel quality ratings. This model may therefore serve as a surrogate for auditory-perceptual assessment of Parkinsonian vowel quality. Furthermore, the model may offer the clinician a tool to predict who may benefit from Levodopa medication in terms of enhanced voice quality.

Treating Velopharyngeal Insufficiency in a Case of Substance Abuse: A New Client Population

Objective A case study is presented to illustrate the management of a patient who presented with significant tissue damage of the soft palate due to substance abuse, which involved the inhalation of drugs. Method The patient was seen in a university medical center cleft palate clinic upon referral from a mental health facility with reported speech and swallowing problems. Perceptual and physiologic speech testing, a behavioral swallowing assessment, and other interdisciplinary assessments were conducted to confirm the patient's complaints and develop a treatment plan. Results A speech appliance was fabricated to correct the defect and follow-up testing showed improvement in both speech and swallowing skills. Perceptual assessment indicated improved resonance balance and reduction in audible nasal emission, while physiologic testing revealed decreased nasal airflow. The team successfully implemented a plan to correct the patient's speech, resonance, and swallowing problems. Conclusions Substance abuse is now a significant national crisis and patients may need a range of services depending on their complex of problems. Some individuals may need assistance with speech, resonance, and swallowing disorders and require prosthetic intervention provided via interdisciplinary management from a cleft palate team.
