Forensic analysis of voice control system data – Forensic use of in-car voice assistants

In-car voice control systems process spoken commands to operate navigation, communication and comfort functions, and in some cases log command histories or times of use.

This data may be relevant for understanding how the vehicle is actually operated whilst driving, as well as any potential distraction caused by interacting with the system.

Since its foundation, LanCologne has specialised in professional IT forensics. Our staff have decades of experience in the field of information technology and assist companies, solicitors, private individuals and, on a regular basis, the courts in the technical investigation of complex digital matters.

The examination is, as a matter of principle, carried out exclusively on a forensic copy, a forensic image or a data source captured in a technically equivalent manner that preserves the integrity of the evidence. The original evidence remains unchanged and is stored in a manner that preserves its integrity.

Our services

We analyse the available log data from the voice control system and document the commands recorded and the times of use during the relevant study period.

Typical areas of application

•Evidence of who was driving the vehicle whilst it was in motion
•Investigation into possible driver distraction
•Supplementing driving profile and accident reconstructions
•Clarification of how it interacts with communication and navigation functions
•Judicial and non-judicial expert reports
•Cooperation with law enforcement agencies in relation to traffic offences

This is how a voice control system analysis is carried out

Once the data has been backed up, the available command and usage logs are extracted and chronologically organised within the sequence of the investigation.

Why is the analysis of voice control systems relevant to forensic investigation?

Evidence of active use whilst driving may be relevant when assessing whether distraction was a cause of the accident.

In some cases, an analysis of the content of recorded commands can also provide additional information about the course of the journey.

Frequently Asked Questions

Are all voice commands stored permanently?+
This varies considerably depending on the manufacturer and the system’s specific privacy settings.
Are audio recordings also stored locally?+
Many systems do not store audio locally on a permanent basis; this is assessed on a case-by-case basis.
Can voice commands be assigned to a specific person?+
Not usually, unless the system uses a voice recognition function.
