FORENSIC: ethimology
The noun forensic, meaning “an argumentative exercise” derives from the
adjective forensic, whose earliest meaning in English is “belonging to, used in, or
suitable to courts or to public discussion and debate.” The English word was derived
from a Latin word forensic meaning “of the market place or form, public,” which in turn
comes from the Latin word forum, meaning “market place, forum.”

‘‘Few professions are as concerned with
language as is the law.’’
—Tiersma, 1993
Forensic linguistics by Shuy
- the use of linguistic knowledge in law cases where data
may serve as evidence
- applied linguistics
(Shuy, 2006, p. 3)
Forensic linguistics by Olsson
The application of linguistic knowledge to a
particular social setting, namely the legal forum
(from which the word forensic is derived).
the interface between language, crime and law …
(Olsson, 2008, p. 3)
AILA (International Association of Applied Linguistics):
-
language of law (documents, courts, prisons, police)
study, provision and improvement of professional
legal interpreting and translation
alleviating linguistic disadvantages
linguistic expertise to provide linguistic evidence
legal drafting
LANGUAGE AND THE
LAW
Law and language:
• framework within which we manage our daily lives
• represents societies value system (imposing rights and obligations,
eg. infanticide)
• linguistic institution, coded in language, concepts are only accessible through
language
Legal processes: court cases, police investigations, contracts
/Gibbons 2003, p. 1/
Legal English
modification of common speech both as regards
vocabulary and as regards syntax
(Russell, 1975 in Gibbons 2003, p. 36)
VOCABULARY
•
•
•
•
Archaic deictics: hereinafter, thereupon,
aforesaid, etc.
Doublets and triplets: due care and attention
Specific vocabulary: murder / manslaughter /
party (legal English ESP)
Latin expressions: caveat, in camera
GRAMMAR
- articles: def/indef or zero? (general vs. general conceptual aspect)
In the event of conflict ….
- split infinitives are not preferred (to boldly go where no one has gone
before)
- nominalisation is not preferred (to make decision vs. decide)
- prepositions are not preferred in sentence final position:
He is one of the people I saw my daughter with.
He is one of the people with whom I saw my daughter.
- Proper use of relative ‘which’ and ‘that’
The evidence which was presented to the jury was accurate. DEF (THAT
is preferred)
The evidence, which was presented to the jury, was accurate. NON-DEF
- Since (causal and temporal relationship) vs. because (causal
relationship)
He has been in home custody since Friday since he is a suspect.
- Shall: only in contracts (obligation) – the parties shall be entitled
/International Legal English – Cambridge University Press/
LAW SYSTEMS
Roman Law
Common Law
Shari’ah
Common Law
also known as the Adversarial System or (misleadingly) as
Anglo-American Law (Gibbons, 2003, p. 5)
• Presumption of innocence until proven guilty
prosecution: to prove guilt beyond reasonable doubt
• Adversarial proceedings
ritualized battle between the prosecution and the
defence, trying to prove conflicting cases (Gibbons, 2003, p.6)
Jury: verdict
Judge: sentence
State attorney: prosecutor (prosecution)
Defence lawyer: defence
Literacy and Law
(Gibbons, 2003, pp.15 - 36)
Two major areas: coded and spoken language
Coded: written, legislation and legal documents
Spoken: interactive, dynamic (language of courtroom,
police investigation, consultations)
(Gibbons, 2003, p.15)

consistency and conservatism
Once legal actions are committed to paper, they can be consulted, relevant
elements can be reproduced.
Detachment from the context results in high levels of autonomy.
Tiersma, 1991:
Three types of legal written texts
Operative documents
Expository documents
Persuasive documents
Operative documents: establish the legal framework
itself
 legislation: acts, orders, statutes
 pleadings
 petitions
 judgements
 contracts
 wills
Expository documents: objectively explaining the
law.
 letter to a client
 office memorandum
 educational materials, books
fairly formal standard English
Persuasive documents:
submissions to convince a court
fairly formal standard English
SPOKEN (oral) LEGAL SYSTEMS
The distinctions between spoken and written legal communication /
language are not absolute.



less planned
increased explicitness
less passive
shorter sentences
speech can refer to the surrounding context between speakers while
written is decontextualised
 usually not retained in visual circumstances
THE INTERACTION OF WRITTEN AND SPOKEN
LANGUAGE
Legal transcription
FORENSIC ANALYSIS
Legal proceedings:
Three stages
• the investigative stage
• the trial stage
• the appeal stage
Investigative stage
Police request opinion on a text or an
interview tape, to assist in developing
interview and interrogation techniques
Trial stage
Common types of linguistic analysis:
•
questions of authorship (Who wrote the text?/
Who is the speaker in this recording?)
•
meaning and interpretation (Does this word
mean X, Y or something else?)
•
threat analysis (Does this text contain a threat?)
•
text provenance and construction (Was the
text dual-authored? Was it written rather than
spoken?)
Expert report to the instructing legal team
(prosecution/defence – plaintiff/claimant
in a civil case)
Expert witness
Appeal stage
- New evidence has been made available
- Existing evidence to be looked at in new
ways
FORENSIC ANALYSIS OF SOUND / VOICE
RECORDINGS
Forensic phoneticians: speaker identification
 Problem: there will always be differences between any two speech
samples, even when they come from the same speaker
 Task:
being able to tell whether the inevitable differences between samples are
more likely to be within-speaker differences or between-speaker differences
(Coulthard & Johnson, 2007, p. 148)
AUDACITY
Voiceprint
Closely analogous to fingerprint identification, which uses the
unique features found in people’s fingerprints, voiceprint
identification uses the unique features found in their utterances.
(Kersta, 1962 in Coulthard & Johnson, 2007, p. 150)
Spectrograms
A spectrogram is a visual
representation of the
spectrum of frequencies in a
sound or other signal
as they vary with time or
some other variable
FORENSIC ANALYSIS OF LEXIS
sentence structure
specifics
Authorship attribution
Idiolect: linguistic fingerprint
A variety of language unique to an individual speaker, a sort of
‘linguistic fingerprint’ which distinguishes him or her from other
speakers of the same dialect.
(Pearce, M. The Routledge dictionary of English studies. 2007, p. 87)
At the practical level in forensic linguistics, there is probably
little need in most authorship investigations to think in terms of
unique style. It is simply not necessary. Rather, when
conducting an investigation, the emphasis should be upon the
relative differences between the candidate authors and how
we can classify their texts. Hence, insofar as it is necessary to
think of style at all, it may be better to focus on
distinctive rather than unique style.
