One important area [ original research? It can also refer to the ongoing attempts at making legal language more comprehensible to laypeople.

A forensic linguistics understanding of the relationship between language and law has been voiced by Leisser who states that. One part of the language of legal texts encompasses the Miranda warning in the United States. These warnings let the defendant know that they have the right to be silent since whatever they say from the point they are in police custody can and will be used against them in a court of law.

The recipients who are advised of these rights must have a certain level of competency in the English language in order to completely understand the warning. Among other things, this area examines language as it is used in cross-examination, evidence presentation, judge's direction, police cautions, police testimonies in court, summing up to a jury, interview techniques, the questioning process in court and in other areas such as police interviews.

Police officers use specific language to elicit certain responses from civilians. Because of a police officers' social stature, and the way they often phrase "requests" as "commands", people may be confused as to what their rights are when they are being questioned by police. Officers use linguistic tactics including putting the blame onto the victim and asking questions with ambiguous phrasing to elicit specific responses from people Solan, L.

A defendant using ambiguity in the courtroom may present issues and be deemed unacceptable. Specifically, when a victim is invoking their right to a lawyer, there are directions stating that the request may not come off as ambiguous. In fact, if the request is not stated in a way that the officer deems to be clear, the victim may not receive their request for counsel at all.

During the examination process, language plays a substantial role in the presentation of a story to the courtroom. Specifically, the language used by the lawyer to construct the story to the courtroom elicits specific responses from the witness, and specific emotions from the jury. For example, in an instance where a lawyer is examining a hostile witness, they will often use language to limit the response of the witness, in order to avoid having the witness present conflicting evidence. In a situation where a lawyer interviews a friendly witness whose testimony could potentially strengthen the story constructed by the lawyer, the opposite may occur where wh-questions are targeted to allow for elaboration Olsson, Luchjenborers, Lawyers employs specific tactics for both themselves and their witnesses to come off as more or less truthful to the jury and the people of the courtroom.

For example, the lawyer may refer to the witness by their first name or a nickname to humanize the witness, or they may speak using slang in order to create less social distance between himself and the courtroom. The lawyer may also avoid using slang, and instead use complicated law terminology to set himself apart from the courtroom and define his status Olsson, Luchjenborers, The lawyer works in constructing the language of the legal process of the courtroom, and specific witnesses may respond to the lawyer's questions in different ways, eliciting new language tactics and opinions from the jury.

For example, witnesses may use direct or indirect speech based on their previous societal experiences, gender differences, socioeconomic differences, or differences in education level. Using particular dialects, slang, or sentence formations could assist in making the witness more or less truthful to the jury Olsson, Luchjenborers, Since language can be used to elicit responses in the legal process, the right to an interpreter plays a part in the fairness of the trial.

In an emergency call, the recipient or emergency operator's ability to extract primarily linguistic information in threatening situations and to come up with the required response in a timely manner is crucial to the successful completion of the call. Emphasis on intonation, voice pitch and the extent to which there is cooperation between the caller and the recipient at any one time are also very important in analyzing an emergency call.

Full cooperation includes frank and timely responses. Urgency plays a role in emergency calls, so hesitations, signs of evasiveness, and incomplete or overly short answers indicate that the caller might be making a false or hoax call.

A genuine call has distinctive interlocking and slight overlap of turns. The recipient trusts the caller to provide accurate information and the caller trusts the recipient to ask only pertinent questions. If the caller uses a rising pitch at the end of every turn, it might represent a lack of commitment; the recipient's use of a rising pitch indicates doubt or desire for clarification.

The call ideally moves from nil knowledge on the part of the recipient to a maximum amount of knowledge in a minimum possible period of time. This makes the emergency call unlike any other kind of service encounter. Threat is a counterpart of a promise and is an important feature in a ransom demand. Ransom demands are also examined to identify between genuine and false threats. An example of a ransom note analysis can be seen in the case of the Lindbergh kidnapping , where the first ransom note sometimes referred to as the Nursery Note stated: "We warn you for making anyding public or for notify the Polise the child is in gut care" sic.

Therefore, the claim is false at the time of writing since the kidnapper had not even encountered the child when he wrote the note. Kidnappers may write statements that later end up being true, such as "your child is being held in a private location" being written ahead of time. Ransom demands in the style of written notes have been present in many notable cases. The style of writing used in ransom notes are examined by forensic linguists in order to determine the writing's true intent, as well as determining who wrote the note.

Forensic linguists look at factors such as syntactic structures, stylistic patterns, punctuation and even spelling while analyzing ransom notes [15]. In the case of the Lindbergh ransom note forensic linguists compared similarities of writing styles from the note to that of writing of the suspect, creating a better chance at discovering who wrote the note [16].

A suicide note is typically brief, concise and highly propositional with a degree of evasiveness. The proposition of genuine suicide is thematic, directed to the addressee or addressees and relevant to the relationship between them. Suicide notes generally have sentences alluding to the act of killing oneself, or the method of suicide that was undertaken.

Genuine suicide letters are short, typically less than words in length.

Death row statements either admit the crime, leaving the witness with an impression of honesty and forthrightness; or deny the crime, leaving the witness with an impression of innocence. They may also denounce witnesses as dishonest, critique law enforcement as corrupt in an attempt to portray innocence or seek an element of revenge in their last moments Olsson Death row statements are within the heavily institutionalized setting of death row prisons. The Forensic Linguistics Institute holds a corpus of these documents and is conducting research on them.

Social media statements are often context specific, and their interpretation can be highly subjective. Forensic application of a selection of stylistic and stylometric techniques in a simulated authorship attribution case involving texts has been done in relation to Facebook. These areas of application have varying degrees of acceptability or reliability within the field.

Linguists have provided evidence in:. Specialist databases of samples of spoken and written natural language called corpora are now frequently used by forensic linguists. These include corpora of suicide notes, mobile phone texts, police statements, police interview records and witness statements. They are used to analyse language, understand how it is used, and to reduce the effort needed to identify words that tend to occur near each other collocations or collocates.

Forensic Linguistics Assignment Essay -- Forensic Science

The identification of whether a given individual said or wrote something relies on analysis of their idiolect , [21] or particular patterns of language use vocabulary, collocations, pronunciation, spelling, grammar, etc. The idiolect is a theoretical construct based on the idea that there is linguistic variation at the group level and hence there may also be linguistic variation at the individual level.

William Labov has stated that nobody has found a "homogenous data" in idiolects, [22] and there are many reasons why it is difficult to provide such evidence. Firstly, language is not an inherited property, but one which is socially acquired. Education can have a profoundly homogenizing effect on language use. The term authorship attribution is now felt to be too deterministic. The paucity of documents ransom notes, threatening letters, etc in most criminal cases in a forensic setting means there is often too little text upon which to base a reliable identification. However, the information provided may be adequate to eliminate a suspect as an author or narrow down an author from a small group of suspects.

Authorship measures that analysts use include word length average, average number of syllables per word, article frequency, type-token ratio, punctuation both in terms of overall density and syntactic boundaries and the measurements of hapax legomena unique words in a text. Statistical approaches include factor analysis , Bayesian statistics , Poisson distribution , multivariate analysis , and discriminant function analysis of function words. The Cusum Cumulative Sum method for text analysis has also been developed. Speakers tend to utilize two to three letter words in a sentence and their utterances tend to include vowel-initial words.

In order to carry out the Cusum test on habits of utilizing two to three letter words and vowel-initial words in a sentential clause, the occurrences of each type of word in the text must be identified and the distribution plotted in each sentence. The Cusum distribution for these two habits will be compared with the average sentence length of the text. The two sets of values should track each other.
