Voice and Speech Disorders

This study examines the immediate electroglottographic effects of straw phonation in singers using four different straws, identifying potential biomarkers for further research.

The paper uses multimodal imaging to show that polymicrobial biofilms degrade silicone voice prosthesis implants by invading the device and releasing silicone particles.

This study shows that Amazonian Dance improves speech prosody, voice quality, and semantic organization in Parkinson's patients more than Nordic Walking.

This paper uses machine learning models to create fast surrogates for biomechanical laryngeal control models, enabling real-time applications with reduced computational costs.

This study investigates how Parkinson's disease affects perception of speech rate and intensity, finding worse rate discrimination in patients and a link between intensity discrimination and disease severity.

This study examines how sentence complexity and length affect pause behavior in Parkinson's disease, finding increased pauses and correlations with cognitive and motor speech deficits.

The paper quantitatively evaluates laryngeal mobility in a rat model using deep learning to assess asymmetry after RLN injury.

This study delivers decorin via hyaluronic acid microgels to prevent vocal fold scarring by inhibiting myofibroblast activation and collagen deposition in a rat model.

This study shows that alpha-synuclein overexpression alone does not cause vocalization deficits in mice, suggesting that aggregate pathology, not overexpression, is responsible for voice issues in Parkinson's disease.

This study examines sensory feedback processing in Parkinson's disease by comparing ERP responses to self-generated and externally-generated voices with amplitude modulation.

This study evaluates the efficacy of dedifferentiated fat cells (DFATs) in treating glottic insufficiency in a rat model, showing improved outcomes with DFATs combined with bFGF.

This study uses an asymmetric vocal fold model to explore how muscle imbalance affects vocal fold vibration, showing significant asymmetry in paralysis and minor asymmetry in dysphonia.

The paper quantifies age-related changes in human laryngeal shape and size, showing sex-specific effects of age, BMI, and height on thyroid cartilage morphology.

This study investigates VGLUT1 expression in rat laryngeal muscles to assess the presence of proprioceptive organs, finding few muscle spindles and no Golgi tendon organs, suggesting alternative proprioceptive structures.

This paper demonstrates that cervical-cranial muscle network features from sEMG can effectively differentiate vocal tasks and detect subtle changes in vocal performance.

This study identifies abnormal neural oscillations in specific brain regions during different stages of phonation in laryngeal dystonia patients, revealing impaired motor preparation and auditory feedback processing.

The paper examines auditory evoked responses to self-produced and heard speech in Parkinson's disease patients, finding abnormal modulation in those without subjective speech deficits.

This paper reviews acoustic prosody studies in right-hemisphere damage, finding weak effects and highlighting methodological limitations.

This study uses speech analysis to classify Parkinson's disease patients' L-DOPA medication states with high accuracy.

This paper uses acoustic speech analysis to detect and assess ALS progression, achieving 79% accuracy for males and 83% for females using a mobile app dataset.
