An utterance is normally produced by a speaker in linear time and the hearer normally correctly identifies the speaker intention in linear time and incrementally. This is hard to understand in a standard competence grammar since languages are highly ambiguous and context-free parsing is not linear. Deterministic utterance generation from intention and n-best Bayesian interpretation, based on the production grammar and the prior probabilities that need to be assumed for other perception do much better.
The basic function the expression you know serves in conversational discourse is said to be that of a pragmatic particle used when the speaker wants the addressee to accept as mutual knowledge (or at least be cooperative with respect to) the propositional content of his utterance. The fact that you know is even used when the addressee is assumed not to know what the speaker is talking about, suggests that it functions at the deference level of politeness, as a striving towards attaining a camaraderie relationship between speaker and hearer.
Intercultural Pragmatics studies how language systems are used in social encounters between speakers who have different first languages and cultures, yet communicate in a common language. The field first emerged in the early 21st century, joining two seemingly antagonistic approaches to pragmatics research: the cognitive-philosophical approach, which considers intention as an a priori mental state of the speaker, and the sociocultural-interactional approach, which considers it as a post factum construct created by both speaker and hearer though conversation.
Meaning in Interaction: An Introduction to Pragmatics
This volume is a comprehensive introductory text which discusses the development of pragmatics - its aims and methodology - and also introduces themes that are not generally covered in other texts. It is an ideal introductory textbook for students of linguistics and for all who are interested in analysing problems in communication. Jenny Thomas focuses on the dynamic nature of speaker meaning, considering the central roles of both speaker and hearer, and takes into account the social and psychological factors involved in the generation and interpretation of utterances.
