Common questions
What can linguistic profiling tell you about a speaker?+
Linguistic profiling estimates a person's regional origin, age, education level, or native language by analyzing speech or text features alone. In forensic contexts, investigators may use these linguistic markers to narrow down a suspect's background without needing a known comparison sample.
Is linguistic profiling used in criminal investigations?+
Yes. Forensic linguists use linguistic features to infer an unknown author or speaker's identity or background. This helps investigators develop leads by establishing profile characteristics from text or speech evidence.
What is discriminatory linguistic profiling?+
This refers to making unfair decisions about housing, employment, or services based on someone's accent or dialect. These judgments rely on stereotyped assumptions linking speech patterns to race or ethnicity, and constitute discrimination.
