Published: November 2018

The present work explores the acoustic characteristics of articulatory deviations near g(lottis) landmarks to derive the correlates of cleft lip and palate speech intelligibility. The speech region around the g landmark is used to compute two different acoustic features, namely, two-dimensional discrete cosine transform based joint spectro-temporal features, and Mel-frequency cepstral coefficients. Sentence-specific acoustic models are built using these features extracted from the normal speakers' group. The mean log-likelihood score for each test utterance is computed and tested as the acoustic correlates of intelligibility. Derived intelligibility measure shows significant correlation ( = 0.78,  < 0.001) with the perceptual ratings.

The diagnosis and treatment of vocal fold disorders heavily rely on the use of laryngoscopy. A comprehensive vocal fold diagnosis requires accurate identification of crucial anatomical structures and potential lesions during laryngoscopy observation. However, existing approaches have yet to explore the joint optimization of the decision-making process, including object detection and image classification tasks simultaneously.

Introduction: Analysis of medial surface dynamics of the vocal folds (VF) is critical to understanding voice production and treatment of voice disorders. We analyzed VF medial surface vibratory dynamics, evaluating the effects of airflow and nerve stimulation using 3D reconstruction and empirical eigenfunctions (EEF).

Article Synopsis
  • The study aimed to explore and compare the vibratory patterns of canine vocal folds to those of human vocal folds, despite their anatomical differences.
  • Researchers used a canine hemilarynx to capture vocal fold vibrations with high-speed video and performed histological examinations to analyze their structure.
  • Findings revealed that canine vocal folds exhibited similar oscillation patterns as humans, indicating that certain structural features might not be essential for producing human-like vocal sounds.

Type I thyroplasty is widely used to improve voice production in patients affected by unilateral vocal fold paralysis. Almost two-thirds of laryngologists report using Silastic® implants to medialize the vocal fold, with implant size, shape, and location determined experientially. However, post-surgical complications arising from this procedure (extrusion, migration, resizing) necessitate revision in 4.

Introduction: Bilateral vocal cord immobility (BVCI) is a leading cause of stridor and airway obstruction in neonates which may arise idiopathically, as a result of birth trauma, or in the setting of Central nervous system lesions such as Arnold-Chiari malformation. Although many children with BVCI may be managed conservatively, surgical intervention may be necessary in those patients with ongoing upper airway obstruction. Many interventions have been described including, tracheostomy, cordotomy, cricoid splitting procedures, and arytenoidectomy.
