This paper displays examples of inconsistencies in spontaneous speech. It refers to cases in which the speaker changes his manner of expression while speaking, even though there generally seems to be no objective reason for doing so. It demonstrates the phenomenon in the use of verb tense, of person inflection, of singular/plural form, and of direct/indirect speech. It suggests that these phenomena be viewed as cases in which the speaker tries (not necessarily consciously) to make his speech less monotonous and more attractive to the listener by providing various ways of expression differing mainly in the degree of closeness they convey between the reported event and the addressee.
