8.1 Speech Acts and Conversational Implicature

Speech acts and conversational implicature are key concepts in pragmatics. They show how we use language to do things beyond just sharing info. These ideas help us understand the hidden meanings and intentions behind what people say.

Understanding speech acts and implicature is crucial for effective communication. They reveal how context, shared knowledge, and cultural norms shape our conversations. This knowledge is useful in everyday life and in fields like linguistics and AI.

1 of 3

• Speech act theory developed by J.L. Austin postulates language performs actions beyond conveying information
• Locutionary acts encompass literal meaning of utterances including phonetic, syntactic, and semantic elements
• Illocutionary acts embody intended meaning or force behind utterances (promising, requesting, warning)
• Perlocutionary acts produce actual effects on listeners (persuading, frightening, inspiring)
• Hierarchical relationship exists among three acts
  • Locutionary acts form foundation
  • Illocutionary acts build upon locutionary acts
  • Perlocutionary acts result from interaction of previous two

Indirect Speech Acts and Felicity Conditions

• Indirect speech acts occur when illocutionary force differs from apparent surface structure
  • Require pragmatic interpretation to understand true meaning
• Success of speech acts depends on meeting felicity conditions
  • Preparatory conditions (speaker has authority to perform act)
  • Sincerity conditions (speaker genuinely intends to carry out act)
  • Essential conditions (utterance changes social reality in some way)

Conversational Implicature

Types and Calculation of Implicatures

• Conversational implicature introduced by H.P. Grice conveys implicit meaning beyond literal interpretation
• Two main types of implicatures
  • Conventional implicatures tied to specific words or phrases
  • Conversational implicatures arise from context of conversation
• Conversational implicatures further divided into
  • Generalized implicatures (occur in most contexts)
  • Particularized implicatures (specific to particular context)
• Calculation of implicatures involves inference process based on
  • Literal meaning of utterance
  • Context of conversation
  • Assumed cooperation between interlocutors

Role and Significance of Implicatures

• Implicatures facilitate efficient communication
  • Allow speakers to convey complex ideas concisely and indirectly
  • Enable communication of more information than explicitly stated
• Rely on shared knowledge and contextual cues for interpretation
• Essential in fields of study
  • Pragmatics
  • Discourse analysis
  • Cross-cultural communication

Gricean Maxims for Cooperation

The Cooperative Principle and Maxims

• Cooperative Principle proposed by H.P. Grice
  • Participants expected to contribute appropriately to achieve accepted purpose of interaction
• Four maxims elaborate on Cooperative Principle
  • Quantity: Provide neither more nor less information than required
  • Quality: Make contribution true and avoid saying things lacking adequate evidence
  • Relevance (Relation): Ensure contributions pertain to ongoing conversation and its goals
  • Manner: Be clear, orderly, and avoid ambiguity or obscurity in expressions
• Violations of maxims can be intentional (leading to implicatures) or unintentional (potentially causing miscommunication)

Applications and Criticisms

• Maxims serve as guidelines for effective communication
  • Not always strictly followed in real conversations
  • Lead to various pragmatic phenomena when flouted or violated
• Critics argue maxims may not be universally applicable
  • Vary across cultures and communication contexts
  • May not account for all nuances of human communication

Context in Speech Interpretation

Contextual Factors in Communication

• Context encompasses physical, social, cultural, and linguistic environment of communication
• Common ground or shared knowledge between interlocutors crucial for interpreting intended meanings
• Contextual factors influencing interpretation
  • Speaker-listener relationship
  • Setting of conversation
  • Prior discourse
  • Cultural norms and expectations
• Cultural context vital in speech act interpretation
  • Different cultures have varying norms for politeness, directness, and appropriate speech acts

Theoretical Developments and Applications

• Principle of relevance proposed by Sperber and Wilson
  • Hearers automatically seek most relevant interpretation of utterance given context
• Context can override literal meaning
  • Allows successful communication even when utterances appear to violate Gricean maxims
• Study of context in speech act theory and implicature led to developments in pragmatics
  • Relevance Theory
  • Neo-Gricean approaches
• Applications in various fields
  • Cross-cultural communication
  • Natural language processing
  • Artificial intelligence
