Conversation Analysis

Forensic linguistic studies also thre structure of spoken conversation by examining how word choices are made to organise exchanges between people. So the forensic phonetics is the use of phonetic technique during the analysis to the sounds that applied to criminal investigation. This technique includes sound technical comparison, voice recognition, transcriptions of spoken language and inclues also the disputed speech transcription and authentication records. We know how the sound is produced by the human vocal organs but we need still a sophisticated technology which can be used to measure tone, color and sound pressure.

The written linguistic evidence or a transcription of conversation will be analyzed by linguistic theories which involve syntactic knowledge to analyze how the text is built and how is based on the structure of the language.

We see how this issue is complex and how it requires a lot of linguistic knowledge.

Questions of forensic linguistics

It is clear that linguistics evidence can play a crucial role in investigating a crime. So sometimes the linguistics evidence in a case is obvious. So I would like to present fundamental questions asked about language-based evidence. All questions are focused on reflecting a case. Often the crucial investigative issues are

1. author/speaker identification: Who authored this document? Who spoke this voicemail message?

2. text similarity: Are these texts or screen names related to each other? Are these trademarks too similar? Are these manuals too close for comfort?

3. text typing: Is this document really what it purports to be --- is it a real suicide note, a real threat letter, a real confession, a real predatory chat, etc?

4. linguistic profiling: What can be determined about the author’s background from this text?

Generally Forensic linguistics is a new-born science which makes connection between linguistics and the law. For this reason it doesn't have terminology. But there are the new approaches:

- terrorism cases
- cross-cultural communication
- similarities in large corpora
- multimodal aspects of victim's narrative

I'm very interested in this branch of linguistic so I would like to read a book about it.Unfortunately, in Poland there isn't this type of book.

Forensic linguistic

Forensic linguistics? I would like to deepen this knowledge. Forensic linguistics (or legal linguistics) is the application of linguistic knowledge and insights to the forensic context of law, language, crime investigation and judicial procedure. This branch of linguistics is very interesting. There are three areas of application for linguists who work in forensix contexts:
1) Understandig language of written law (it isn't so easy)
2) Understanding language use in forensic and judicial processes
3) the provision of linguistic evidence

So forensic linguistics covers all areas where language and law intersect. The concept first appeared in 1968 when a progessor of linguistics, Jan Svartvik, used it in an analysis of statements by T.J. Evans. In the 1980s, Australian linguistis discussed the application of linguistics to legal issues and they dispovered that a phrase such as 'the same language' is open to interpretation not only by lawyers but also by linguists.
