Objectives:
The aim of the study is to determine the accuracy of acoustic spectrography as an outstanding tool in the characterization and monitoring of esophageal voice.
Material And Methods:
Our subjects were comprised of 33 laryngectomized patients (all male) that underwent qualitative acoustic (spectrography of vowel /a/ and a sentence), quantitative acoustic (phonation time, fundamental frequency, maximun intensity sound level, speech rate) and perceptual protocol.
Results:
There is a significant statistical relationship among Yanagihara-like spectrographic chart classification, psycho-acoustical perception and quantitative acoustic parameters.
Conclusion:
We consider that acoustic spectrography is an easy, effective method for studying esophageal voice, seeking for improving oral communication skills and rehabilitation in the laryngectomee population.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
