This project is funded by the French National Research Agency (ANR). It is the first time some French public research labs have teamed up with the forensics labs of Police Nationale and Gendarmerie Nationale. Our aim is to establish a reliable and officially certified workflow in the field of forensic voice comparison. I’m involved in 2 key aspects of the project:
