AUDIO Analysis and Authentication Services

Due to the open source of audio editing software, audio analysis and authentication services are in demand more than ever before. Today's technology provides ample opportunity for domestic users to record conversations on the fly in real time. Domestic software packages and third party addon programs allow the home user or hobbyist to rearrange or edit recorded material. Hence this facilitates the importance of experts to analyse material for its authentication and produce certified documentation and reports on their findings to verify continuity or discontinuity of audio recordings.

ANALYSIS reports

Audio forensic evidence analysis reports are presented to clients in order to assist in areas which require a recording to be proven legitimate.
The authentication of recordings are an integral part of Audio Forensic Services to present recordings as a valid piece of evidence. Various techniques are implemented to analyse and authenticate a recording. This varies depending on the original recording device used to capture a specific moment in time.
Verification of recordings rely on techniques to detect editing or tampering.

Voice and Speech Dialogue Analysis

Voice and Speech dialogue analysis and forensic speech analysis applies to the voice comparison of two or more voice or speech samples to determine whether each voice pattern matches. This procedure is classed as voice forensic analysis comparison.
Speech recognition analysis and voice comparisons are presented in professional reports clearly indicating and pinpointing continuity or discontinuity when analysing a dialogue audio recording. The recordings are processed through specific industry recognised voice analysis software programs, whereby formant calculations are analysed and graded. Linguistic experts will also study the phonetics and speech patterns of dialogue to present an aural analysis of the recording of which strengthens the high or low probability rating of a voice match.

To clarify and confirm authenticity Audio Forensic Services conduct investigations to detect and verify signs of any discontinuities, tampering or editing within a recording. Sound files can be subjected to tampering when they are taken out of their original recording environment. At AFS we have the facilities, knowledge and technology to perform the required tasks and formulate supporting reports to be used as evidence in disputes, litigation, legal matters and court hearings to confirm continuity and authentication or prove corruption and alteration. 
Digital voice recorders can be used for domestic purposes or commercial as in the form of black box data recordings. Whether it be a domestic, legal or tribunal analysis report required, AFS can assist in these areas of service.
