Discourse analysis

Language as Action

What is “discourse”?
 Discourse is:
 language above the sentence or above the clause
 a continuous stretch of spoken language larger than a
sentence, often constituting a coherent unit
 a stretch of language perceived to be meaningful unified,
and purposive; language in use
 (viewed) as social practice determined by social
structures

Structural and functional
definitions of discourse
 Structural or textual definition of discourse:
Discourse is a particular unit of language (above
the sentence).
 Functional definition of discourse:
Discourse is a particular focus of language use.

Structural approach to discourse
 Find the constituents that have particular relationships
with each other and that can occur in a restricted number
of arrangements;
 Problems: units in which people speak do not always
look like sentences, or grammatically correct sentences.
Example 1
(From “The Colour Purple”, Alice Wharton)
Jack is tall and kind and don't hardly say anything. Love children.
Respect his wife, Odessa, and all Odessa Amazon sisters (Celie’s
Diary)

Structural approach to discourse
 Examples, like Colourless green ideas sleep furiously
(Chomsky);
 Solving the problem: adopt Lyons’s distinction between
system-sentences and text – sentences. System
sentences are well-formed abstract theoretical
sentences generated according to the existing grammar
rules; text-sentences are context-dependent utterances
or parts of utterances which occur in everyday life.
 The discourse analysis will be concerned with text-
sentences.

Functional approach to discourse
 Roman Jakobson: language performs six
functions:
 Addressor(emotive);
 Context (referential)
 Addressee (conative);
 Contact (phatic);
 Message (poetic);
 Code (metalinguistic).

Functional approach to discourse
 Utterances may have multiple functions;
 The major concern: discourse analysis
can turn out into a more general and
broader analysis of language functions. Or
it will fail to make a special place for the
analysis of relationships between
utterances.

Recent approach to DA
 Discourse is no longer studies for its own
sake. Discourse is viewed as a social
practice.
 M. Foucault, N. Fairclough

 Discourse is characterised as:
 produced/consumed/monitored by social
actors (producers/receivers of social
practices);
 shaped by social structures;
 with social implications;
 socially valued and regulated (production,
reception and circulation).

 If in traditional studies discourses were analysed
in relation to social processes that form them,
then recently researchers started talking about
bidirectional and complex relations between
discourses and social practices:
Discourses of food Social Practice
“Healthy Food” Healthy lifestyle

What Makes Discourse
Different?
 Similarities (to monologues)
Anaphora
Discourse structure & coherence
 Key Differences
Turns and utterances
Grounding
Conversational implicature

Different?
 Property #1: Turns and utterances
 Speaker A … then Speaker B … etc.
 Timing and turn-switching
 Levinson (1983) suggests that less than 5% of
American English dialogue is overlapped
 Task-oriented dialogue … even LESS overlap!
 Natural conversation requires knowing
 WHO should speak next … and …
 WHEN they should speak

Different?
 Conversational Analysis (CA)
 Sacks et al. (1974) argued that turn-taking
behavior is governed by a set of rules
 At each TRP (transition-relevance place) …
A. If current speaker selects Speaker A as the next
speaker, then Speaker A must speak next
B. If no speaker selected, any other may take turn
C. If no one else takes the turn, the current speaker
may take the next turn

Different?
 Implications of Sacks’ rules
 Adjacency pairs
 Question-answer … Request-grant … etc.
 Interpreting silence
 Refusal to respond? A “dispreferred” response?
 TRPs generally at utterance boundaries
 Utterance boundary detection critically important
 Current boundary algorithms based on: Cue words,
N-gram word or POS sequences, and prosody

Different?
 Property #2: Grounding
Dialogue is a collective act requiring “common
ground” (Stalnaker, 1978)
 Listener must acknowledge (ground) the speaker’s
utterances
 Achieved through “backchanneling”
 Listener indicates problems by issuing a “request
for repair”

Different?
 Property #3: Implicature
Interpretation of an utterance relies on more
than just the literal meanings
Grice (1975, 1978)
 Theory of Conversational Implicature
 Proposed that what enables listeners to draw
inferences are guided by a set of maxims
(heuristics for interpretations)

Different?
 Property #3: Implicature
 Grice’s Maxims (1975, 1978)
 Maxim of Quantity
 Be exactly as informative as is required
 Maxim of Quality
 Try to make your contribution one that is true
 Maxim of Relevance
 Be relevant
 Maxim of Manner
 Be perspicuous (Avoid obscurity & ambiguity)

Argues that truth conditions are not central to language
understanding. Utterances do not only say things, they
do things.
Distinction between constatives and performatives.
Performatives cannot be false, but they can fail to do things.
Performatives are not a special class of sentences. Some
sentences are explicitly performatives, others can be implicitly.
The performative/constative distinction does not really exist.
Rather, they are special cases of a set of illocutionary acts.
Austin’s Speech Act Theory

Speech Acts
 Austin (1962)
 An utterance in dialogue is an ACTION
 Speech acts
 Performative sentences uttered by an authority
(they change the state of the world)
 Any sentence in real speech contains
 Locutionary act – utterance with particular meaning
 Illocutionary act – asking, answering, promising, etc.
 Perlocutionary act – effect upon feelings, thoughts, etc.

Speech Acts
 Searle (1975)
 All speech acts classified as
 Assertives – suggesting, boasting, concluding, etc.
 Directives – asking, ordering, inviting, etc.
 Commissives – promising, planning, vowing, etc.
 Expressives – thanking, apologizing, deploring, etc.
 Declarations – performatives (state-changing)

Speech act theory
 Developed by two philosophers: John Austin and John
Searle;
 Austin (“How to do things with words”): some sentences
are used not just to state something, which is true or
false:
Example 1
I apologize.
I declare the meeting open.
 These sentences are used to do things. They are
performatives/ vs. all other utterances – constatives.

Speech act theory
 Differentiation between performatives and constatives:
adverb “hereby”
Example 2
I hereby apologize.
I hereby declare the meeting open.
 Examples of performative verbs in English:
to withdraw
to declare
to plead
to vote
to thank, etc.
to say
to protest
to object
to apologize
to deny
to promise

Speech act theory
 Constatives can be true or false; performatives can't be true or
false. But performatives can go wrong;
 Conditions for performative sentences, which make them
successful ("felicitous“ conditions):
 Condition 1:
 There must be a conventional procedure following a
conventional effect;
 The circumstances and the persons must be appropriate.
 Condition 2:
 The procedure must be executed:
 Correctly;
 Completely.

Speech act theory
 Condition 3:
 Often
 The person must have the requisite thoughts,
feelings and intentions, as specified in the
procedure;
 If consequent conduct is specified, then the relevant
parties must do so.
Favorite examples: marriages

Speech act theory
 Types of speech acts:
 Verdictives (e.g. estimating, assessing, describing);
 Exercitives (ordering, appointing, advising);
 Commissives (promising, betting);
 Behabitives (apologizing, congratulating, thanking);
 Expositives (arguing, insisting).

Speech act theory
 Performatives: explicit and implicit;
 Performatives and constatives are just two
subclasses of illocutionary acts;
 Illocutionary acts consist of other classes
of speech acts.

Speech act theory
Each speech act consists of 3 components:
 Locutionary act (the actual words which the speaker is
saying);
 Illocutionary act (the intention of the speaker);
 Perlocutionary act (the effect of the utterance on the
hearer).
Example 3
(From "Sense and Sensibility")
Wait, he is kneeling down.

Speech act theory
 Compare Austin’s classification with other classification of speech
acts
Conclusions for DA:
 speech act theory is concerned with what people do with language or
it is concerned with the function of language.;
 a piece of discourse (what is said) is chunked/segmented into units
that have communicative functions,;
 these function are identified and labelled;
 different speech acts initiate and respond to other acts. Acts to a
certain degree specify what kind of response is expected;
 they create options for a next utterance each time they are
performed;
 An utterance can perform more than one speech act at a time ;
 there is more than one option of responses for a next utterance;
 Deborah Schiffrin: ‘this flexibility has an important analytical
consequence: it means that a single sequence of utterances may
actually be the outcome of a fairly wide range of different underlying
functional relations.’

Pragmatics
 Based primarily on the ideas of Paul Grice:
 People interact having minimal assumptions
(implicatures) about one another;
 Two types of implicatures: conventional and
conversational;
 Conventional implicatures do not require any particular
context in order to be understood (or inferred);
 Conversational implicatures are context – dependant.
What is implied varies according to the context of an
utterance.

Pragmatics
 To explain HOW we interpret implicatures
Grice introduced the Cooperative
Principal:
 Make your contribution such as
required, at the stage at which it
occurs, by the accepted purpose or
direction of the talk exchange in which
you are engaged.

Pragmatics
 There are four conversational maxims which help us to
realize the implicit meaning if an utterance:
 Maxim of Quantity:
Make your contributions as informative as required (for
the current purposes of the exchange). Do not make
your contribution more informative than required.
 Maxim of Quality:
Do not say what you believe to be false. Do not say
something if you lack adequate evidence.

Pragmatics
 Maxim of Relation:
Be relative.
 Maxim of Manner:
Be perspicuous (or express your ideas clearly)
Avoid obscurity of expressions (= do not use expressions which
are not clear or easy to understand);
Avoid ambiguity (= presence of more than one meaning);
Be brief (avoid unnecessary usage of too many words);
Be orderly.

Pragmatics
 The contribution of Gricean pragmatics to
DA is a set of principles that constrains
speakers’ sequential choices in a text and
allows hearers to recognize speaker’s
intentions.
