With progress in practice, the instructor will monitor this condition, and you will gradually realize that you must produce esophageal joice from the stomach. In other words, the air taken into the esophagus should be squeezed up firmly by tightening the abdominal muscle, while you try at the same time to limit, insofar as possible, exhalation through the tracheostoma and change to this method. This is called deep abdominal respiration.
This leads to the conclusion that the size of the aperture has nothing to do with speech production.
Q-2 Role of the nose after surgery
After surgery, if I breathe through the tracheostoma, then doesn't the nose become sort of a "white elephant?"
A-2 Recovery of the olfactory sense and resonance in the nasal cavity
You cannot breathe through the nose as you did before, since you now breathe mostly through the tracheostoma.
・ Gargling and the olfactory sense
During the practice of esophageal speech, proficiency in inhalation method, i.e., speaking by taking air into the esophagus through the nose, permits an improved way of gargling.
