  • Publication number: 20240404521
    Abstract: This disclosure describes, in part, context-based device arbitration techniques to select a voice-enabled device from multiple voice-enabled devices to provide a response to a command included in a speech utterance of a user. In some examples, the context-driven arbitration techniques may include determining a ranked list of voice-enabled devices that are ranked based on audio signal metric values for audio signals generated by each voice-enabled device, and iteratively moving through the list to determine, based on device states of the voice-enabled devices, whether one of the voice-enabled devices can perform an action responsive to the command. If the voice-enabled devices that detected the speech utterance are unable to perform the action responsive to the command, all other voice-enabled devices associated with an account may be analyzed to determine whether one of the other voice-enabled devices can perform the action responsive to the command in the speech utterance.

  • Patent number: 11126440
    Abstract: Techniques for identifying thermal critical conditions in devices with multiple SoCs, and coordinating the resetting and rebooting of the SoCs to recover from the thermal critical conditions are described herein. A device may include a first SoC that monitors a first temperature sensor, and a second SoC that monitors a second temperature sensor, to determine whether temperatures in the device indicate thermal critical conditions. The second SoC may determine that a temperature determined using the second temperature sensor is above a threshold indicating a thermal critical condition, and may provide an indication to the first SoC that the temperature is above the threshold. The first SoC may detect the indication, and the first SoC and second SoC may each reset to allow the device to cool down. The first SoC and second SoC may then coordinate rebooting once the thermal critical condition is no longer detected in the device.
