Larynx

Larynx

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, corniculates, and...

Double Resonance Techniques: Overview

Double Resonance Techniques: Overview

Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.
Spin decoupling is usually achieved by...

The Hyoid Bone

The Hyoid Bone

The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

Expansion and Contraction in Masonry Walls

Expansion and Contraction in Masonry Walls

Masonry walls are subject to slight expansion and contraction due to variations in temperature and moisture. Thermal movement in masonry is relatively straightforward to measure and plan for. On the other hand, moisture movement poses more of a challenge. New clay masonry units typically absorb water and expand over time under normal environmental conditions. Conversely, new concrete masonry units tend to shrink as they lose the excess moisture acquired during their production process.

Problem-Solving: Tuning of a Guitar String

Problem-Solving: Tuning of a Guitar String

In the case of stringed instruments like the guitar, the elastic property that determines the speed of the sound produced is its linear mass density or the mass per unit length. This is simply called the linear density. If the string's linear density is constant along the string, then the linear density is simply the total mass divided by the total length.
The string's wave speed can be regulated by varying the linear density. Tension is the other property that determines the speed of...

Pharynx

Pharynx

The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

Background:

Accurate definition of vocal tract constrictions is crucial for understanding speech production.
Previous methods for identifying constrictions in high front vowels lacked robustness.
Variations in vocal tract shape and defining parameters can affect constriction measurement accuracy.

Purpose of the Study:

To develop a consistent and robust method for defining vocal tract constrictions in high front vowels.
To create a procedure insensitive to local vocal tract shape fluctuations.
To establish a definition method independent of specific constriction-defining parameters.

Main Methods:

Devised a procedure to identify the length and position of articulatory constrictions.
Focused on high front vowels.
Employed visual examination of plots showing constriction properties against defining parameters.

Main Results:

The developed method provides stable definitions for vocal tract constrictions.
The procedure is not sensitive to local vocal tract shape variations.
Constriction definitions are robust across different defining parameters.

Conclusions:

A reliable method for defining vocal tract constrictions in high front vowels has been established.
Visual examination of parameter-dependent plots offers a stable approach.
This method enhances the accuracy and consistency of phonetic analysis.
