Speech error in the context of Utterance

Language production is the production of spoken or written language. In psycholinguistics, it describes all of the stages between having a concept to express and translating that concept into linguistic forms. These stages have been described in two types of processing models: the lexical access models and the serial models. Through these models, psycholinguists can look into how speeches are produced in different ways, such as when the speaker is bilingual. Psycholinguists learn more about these models and different kinds of speech by using language production research methods that include collecting speech errors and elicited production tasks.

A malapropism (/ˈmæləprɒpɪzəm/; also called a malaprop, acyrologia or Dogberryism) is the incorrect use of a word in place of a word with a similar sound, either unintentionally or for comedic effect, resulting in a nonsensical, often humorous utterance. An example is the statement attributed to baseball player Yogi Berra, regarding switch hitters, "He hits from both sides of the plate. He's amphibious", with the accidental use of amphibious rather than the intended ambidextrous. Malapropisms often occur as errors in natural speech and are sometimes the subject of media attention, especially when made by politicians or other prominent individuals.

The term linguistic performance was used by Noam Chomsky in 1960 to describe "the actual use of language in concrete situations". It is used to describe both the production, sometimes called parole, as well as the comprehension of language. Performance is defined in opposition to "competence", the latter describing the mental knowledge that a speaker or listener has of language.

Part of the motivation for the distinction between performance and competence comes from speech errors: despite having a perfect understanding of the correct forms, a speaker of a language may unintentionally produce incorrect forms. This is because performance occurs in real situations, and so is subject to many non-linguistic influences. For example, distractions or memory limitations can affect lexical retrieval (Chomsky 1965:3), and give rise to errors in both production and perception. Such non-linguistic factors are completely independent of the actual knowledge of language, and establish that speakers' knowledge of language (their competence) is distinct from their actual use of language (their performance).

In applied linguistics, an error is an unintended deviation from the immanent rules of a language variety made by a second language learner. Such errors result from the learner's lack of knowledge of the correct rules of the target language variety. A significant distinction is generally made between errors (systematic deviations) and mistakes (speech performance errors) which are not treated the same from a linguistic viewpoint. The study of learners' errors has been the main area of investigation by linguists in the history of second-language acquisition research.

In prescriptivist contexts, the terms "error" and "mistake" are also used to describe usages that are considered non-standard or otherwise discouraged normatively. Such usages, however, would not be considered true errors by the majority of linguistic scholars. Modern linguistics generally does not make such judgments about regularly occurring native speech, rejecting the idea of linguistic correctness as scientifically untenable, or at least approaching the concept of correct usage in relative terms. Social perceptions and value claims about different speech varieties, although common socially, are not normally supported by linguistics.
