Glossary

• Artificial Intelligence (AI): This refers to a machine that learns, generalises, or infers meaning from input, thereby reproducing or surpassing human performance. The term AI can also be used loosely to describe a machine's ability to perform repetitive tasks without guidance.
• Audit Trail (AT): Refers to the documentation processes that capture, record, and report the sequence of actions applied to digital evidence. An AT may include details such as model configurations, parameters used, error rates, human interventions, and system-generated logs. It functions as a transparency mechanism, enabling the reconstruction and evaluation of how evidence has been processed, analysed, and interpreted.
• Automatic Speech Recognition (ASR): A subfield of AI that processes spoken human language (audio) and converts it into written text, useful for tasks like transcription and speaker diarisation.
• Chain of Custody (CoC): This is the record of how evidence is handled from the point of collection through processing to presentation in court. This may include the identity of the person handling the evidence, date/time of transfer, storage details, and digital identifiers. Alternative terms include 'continuity', 'chain of evidence' and 'provenance'.
• Forensic Audio evidence: This refers to recorded sound collected, preserved, and analysed for legal or investigative purposes. This often includes spoken language from sources including body-worn cameras, dashcams, police radio communications, and interview or interrogation recordings.
