Larynx01:21

Larynx

6.2K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Area of Science:

  • Acoustics
  • Medical Imaging
  • Speech Science

Background:

  • Vocal tract morphology significantly influences voice production, with implications for education and voice therapy.
  • Current understanding of vocal tract spatial geometry during phonation is limited due to data acquisition challenges.
  • Accurate vocal tract geometry data is crucial for detailed analysis of voice production.

Purpose of the Study:

  • To introduce a novel centerline-based segmentation method for extracting vocal tract geometry from MRI data.
  • To enable efficient and detailed 3D measurements of vocal tract morphology during sustained vowel phonation.
  • To improve the analysis of vocal tract adjustments during speech and singing.

Main Methods:

  • Utilized a centerline-based segmentation approach with active contours.
  • Applied the method to Magnetic Resonance Imaging (MRI) data acquired during sustained vowel phonation.
  • Developed a semiautomatic algorithm for time- and interaction-efficient geometry extraction.

Main Results:

  • The semiautomatic algorithm proved to be time- and interaction-efficient.
  • The method successfully extracted vocal tract geometry data from MRI scans.
  • The resulting 3D models allowed for comprehensive morphological measurements.

Conclusions:

  • The developed method offers an efficient way to obtain detailed vocal tract geometry.
  • This technique facilitates improved analysis of vocal tract morphology during phonation.
  • Insights into the mechanical processes of speech and singing may be gained through this approach.
