Widespread ignorance on the vitality of forensic linguistics has led to some of the most egregious miscarriages of justice in Australian history. These non-technical interpretations are easy to conflate with the academic discipline of linguistics.īut apart from causing linguists a headache at dinner parties, does it really matter if people misunderstand what linguists do? Some people think this refers to a person who speaks many different languages, or is particularly fluent in their speech or writing. It comes down to how we use the word “linguist”. Ironically, a big problem for forensic linguists (and linguistics in general) relates to language. Yet the work done by forensic linguists seems to largely elude members of the public. Since the first known forensic linguistic case in 1953, all of the above abilities have proven invaluable in courts time and time again. This is because the variety of English they’re familiar with would differ, in small but notable ways, from native English speakers. For example, we can identify when someone from a non-English language background might misunderstand a question. Sociolinguistics, which looks at how language use varies across different social groups. We can recognise subtle differences in the sound of a vowel when produced by different speakers, or by speakers of different dialects and languages.

Phonetics and phonology, which refer to the sounds of language. Semantics, which explores how speakers and listeners form meaning, such as when making sense of a written text Grammatical structures, wherein changes in punctuation patterns between texts can signal different authors Thus, linguists are uniquely placed to provide expert opinions on how language is used. Linguistics is the scientific study of language.

Reading between the lines (and everything else) Take a look at the organizations website for current news from the field.Forensic linguists can provide expert opinion on a variety of language-related dilemmas, including unattributed voice recordings, false confessions, trademark disputes and, of course, a fair share of threatening letters.įorensic linguists can provide expert opinion on a variety of language-related dilemmas, including unattributed voice recordings, false confessions, trademark disputes and, of course, a fair share of threatening letters. The International Association of Forensic Linguistics. In particular, Bentley’s use of ‘then’ immediately after the subject of a clause, was shown to be more typical of the discourse of police statements than of everyday speech.Īnother Example here of the use of corpus in forensic linguistics! By comparing the number of occurrences in a mini corpus of statements with the number of occurrences in a corpus of everyday English, Coulthard showed how Bentley used this particular word with significant frequency (one in every 58 words, compared with once in every 500).įurther analysis of the texts from the Bentley corpus showed that Bentley’s use of the word ‘then’ had more in common with the use found in a corpus of police statements than it did with use of ‘then’ in everyday speech. One area of Coulthard’s analysis focused on the use of the word ‘then’ in Bentley’s statements. The linguist called upon to give evidence was Professor Malcolm Coulthard (now at Aston University, UK). The Derek Bentley Case in the UK is a good example of an instance where the use of corpus linguistic techniques allowed a conviction for murder to be overturned and a pardon granted, albeit posthumously. There are a number of famous cases which have involved corpora and forensic linguistics. In the case of written language, an expert may be asked to give evidence relating to whether a document was written by a particular person. For example, an expert on spoken language may be asked to identify a voice on a recording, or perhaps decide if a suspect was really able to comprehend what was asked of him or her during an interrogation. There are many branches of forensic linguistics 1, but the basic premise is that the evidence of linguists can be used in both civil and criminal court cases.
