Pressured Speech
Pressured speech (or pressure of speech) is a rapid and accelerated way of speaking that is not 'normal' in regards to the situation. The individual will speak so quickly that the speech may even be incoherent. It is normal to speak quickly sometimes (like in an emergency or a time constrained situation) but people exhibiting pressured speech will do this as if it is a normal conversation. This is a symptom of certain mental conditions like schizophrenia, manic episodes, and anxiety. It can also be a symptom of using stimulant drugs like amphetamines.
