Questioned content analysis

Forensic

Questioned content analysis involving acoustic investigations of speech segments and higher order phonetic features is used where it is very important to establish what has been said in a specific, localised area of a recording.

Analysis

If it is not possible to transcribe the content of a recording just by careful and repeated listening, our analysts use computer-based spectral analysis to provide a suggested interpretation or to provide support for one of a number of competing interpretations.  By analysing the specific sounds with reference to a speaker’s overall speech patterns, it is often possible to determine what was said.

Case examples

J P French Associates have undertaken questioned content analysis in a number of cases, some of which are illustrated in our cases page.
