Automatic speaker comparison

Netherlands Forensic Institute

In criminal investigations, voice comparison is used to find out whether the suspect's and offender's voices are the same. One of the methods that can be used for this purpose is automatic speaker comparison.

Goal and impact

The algorithm supports the decisions made by experts in trace investigation. It is deployed alongside the investigation done only by the experts. The algorithm is deployed because it makes the final verdict even more objective than it would be without an algorithm, because it is possible to measure how well an algorithm works.

Considerations

The algorithm ensures that the final verdict of the expert in trace evidence is more objective and measurable. The process is conducive to efficient and proper criminal justice.

Human intervention

There is human intervention in the use of the algorithm. The result of the algorithm automatic speaker comparison is taken together with the result of the method involving human listening and comparison.
