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.

  • Publication number: 20240294093
    Abstract: A device for discharging a high-voltage (“HV”) battery pack in an electrical system having a low-voltage (“LV”) bus and a high-voltage (“HV”) bus includes a resistive load and an electronic control unit (“ECU”). The ECU transmits electronic control signals to the resistive load to change an output state of the resistive load. As part of a related method, the ECU receives a state of charge (“SOC”) of the battery pack and an auxiliary voltage level of the LV bus. The ECU then selectively adjusts the electronic control signals in response to the SOC and auxiliary voltage level to optimize the output state of the resistive load. This continues until the SOC is within a specified SOC range.
