A close look at this phenomenon shows that there are cases in which air is drawn into the esophagus together with an aspirating sound and in which it is not.
A sound of inhalation is often made when air is taken in through the mouth. Some cases can be cured, then by having speakers close their mouths and breathe through their noises.
Both the injection and inhalation sounds can be eliminated by careful monitoring during the initial stage of speech training or by having the speaker pay attention and listen for such sounds. Once these sounds become a habit, however, they are usually hard to get rid of, and this must be taken into consideration.
(4) Avoiding sounds caught in saliva
During speech training, it is essential to learn to speak only after swallowing as much saliva as possible. Saliva not swallowed because you are absorbed in conversation, for example, collects in the lower part of the hypopharynx. When sound is produced and the new glottis vibrates, the collected salive scatters, hampering speech and making the resulting voice hoarse and clouded, worsening articulation.
