Abstract: A voice-biometrics based solution for unwanted self-invocations by virtual assistant applications is proposed. In various embodiments, a processing system is configured to control a virtual assistant. The processing system may have stored in a memory at least one voiceprint created using voice biometrics based on recorded utterances of synthetic speech from the virtual assistant. The at least one voiceprint may be used to prevent self-invocation of a virtual speech session by matching the voiceprint created using the synthetic speech utterances with the incoming audio stream.

Abstract: A method for determining a sampling rate of occupancy data for a vehicle includes determining a vehicle speed and detecting whether an interrupt condition is present. If the speed is within a first speed range and no interrupt condition is detected, then a first sampling rate is selected for sampling the occupancy data. If the speed is within a second speed range that is higher than the first speed range, and/or if the interrupt condition is detected, then a second sampling rate which is faster than the first sampling rate is selected for sampling the occupancy data. A primary electronic control unit (ECU) may be configured for sampling the occupancy data. If the second sampling rate is selected and a computational demand of the primary ECU exceeds a predetermined threshold, then a portion of the computational demand may be transferred to one or more secondary ECUs for sampling the data.
