2. Concerns During Practice
(1) Noises from the tracheostoma
New students tend to form the same speech habits as before surgery, in which the chest is constricted even though they have been taught otherwise by the instructor, and attempt to produce basic sounds this way. The result, however, is noises resulting from heavy breathing given out through the tracheostoma. Sometimes it cannot be determined whether the basic sounds are produced or not. Upon sudden exhalation from the tracheostoma, the chest constricts, the esophagus contracts, and abdominal pressure is no longer applied. This is useless because all you do is get tired, no matter how much you practice.
Another reason for such noises can be explained as follows:
The front of the trachea is surrounded by a ring of cartilage, but the back is soft tissue, without this cartilage, which comes in contact with the esophagus in the chest.
During speech, pressure is suddenly applied to the esophagus from below, when the back of the trachea comes under pressured, thereby narrowing the trachea and further increasing noise resulting from inhalation.
