What is forensic linguistics?

How does forensic linguistics work?

Forensic linguistics is the study of language in legal contexts. It analyzes linguistic patterns, styles, and variations to aid in investigations, court proceedings, and crime-solving. Linguists, often working in collaboration with law enforcement and legal professionals, employ linguistic techniques to analyze written or spoken language to extract valuable information. Some language techniques forensic linguists may use include:

• Leading questions
• Use of closed or open-ended questions
• Jargon and terminology

Written language encompasses documents or recorded text while spoken language refers to verbal communication that can be used as evidential support in a case.

When applying these branches of linguistic evidence, linguists analyze various elements of language and compare them to the language patterns of victims. These language elements include:

• Syntax: The arrangement of words and phrases to create sentences.
• Register: The style and formality of language.
• Dialect: A variety of language, which can include colloquialisms, that is specific to a region or social group. For example, African American English is a dialect shared by black people in the United States.
• Idiolect: The specific dialect of an individual that includes their vocabulary- and pronunciation.

What are some examples of linguistic evidence?

Forensic linguists are tactically employed to analyze certain legal documents and aid the investigation process. Some examples of forensic texts include:

Emergency call

In an emergency call, an emergency operator extracts linguistic information in a life-threatening situation to respond to the call swiftly and appropriately. Operators pay close attention to vocal pitch, intonation, and cooperative communication. Attentiveness to these elements is critical to successfully completing a call.

Threatening letters

Forensic linguists can analyze ransom and threatening letters, comparing linguistic features to writing samples. They can identify potential suspects based on linguistic patterns, syntax, and other features to support the law enforcement’s investigation.

Social media and online communication

Within the digital age, social media, texting, and cybercrimes are common. Forensic linguistics plays a crucial role in deciphering anonymous online communication. By scrutinizing language style, grammar, and word choice, linguists can help unmask individuals involved in cyber threats, harassment, or other illicit activities on the internet.

Testimony in court

Forensic linguists often serve as expert witnesses in court. They explain their analyses to judges and juries, helping them understand the linguistic evidence presented. This testimony can be pivotal in influencing legal decisions and ensuring justice is served.

Confessions

Confessions provide an account of a criminal’s involvement in a crime. Linguists play a crucial role in evaluating the authenticity of these confessions and written statements. They meticulously examine writing styles and assess consistencies between the evidence presented and the way the perpetrators have expressed themselves in writing.

Forensic linguistics is a powerful tool for criminal and civil cases. Linguists’ critical examination of emergency calls, life-threatening letters, social media, and other forms of communication is valuable in aiding investigation, cases, and society’s wellbeing.
