・ Inhalation-injection
The mixture of inhalation and injection supplies the amount of air obtained by inhalation. This combination enables the speaker to intake air more quickly. Many advanced speakers use this method.
The ratio of inhalation to injection varies from individual to individual. One who can take in enough air to speak by one action of inhalation may not inject after that. In this case, inhalation seems to be almost perfect.
・ Injection-inhalation
The injection of air precedes inhalation due to a long habit of injection, but this style is rare.
