This abstract first appeared for US patent application 20240420695 titled 'APPARATUS AND METHOD FOR PROVIDING A WAKE-UP SIGNAL

Original Abstract Submitted

a control system for a vehicle includes input means, memory means, and processing means, wherein a wake-up engine is arranged to determine a timestamp in dependence on a predetermined event associated with activation of the wake-up engine, analyse a received audio signal to detect an acoustic event indicative of a wake-up signal for a client application, provide an indication of the timestamp and an indication of the detection of the acoustic event comprising an indication of a time of a predetermined point in the audio signal associated with the acoustic event, wherein the indication is relative to the timestamp, wherein the client application is arranged to receive the indication of the timestamp and the indication of the detection, determine a current timestamp in dependence on receiving the indication of the detection, and determine, in dependence on the current timestamp, the first timestamp, and the indication of the time of the predetermined point in the audio signal, a position of the audio signal in the first buffer for initiating an audio session.
