1. A system, comprising:
a data processing system comprising one or more processors and memory to:
identify a plurality of digital assistant devices associated with an electronic account, the plurality of digital assistant devices comprising a first digital assistant device and a second digital assistant device;
determine, based on a machine learning model, to set the first digital assistant device as the primary signal processor and the second digital assistant device as the secondary signal processor;
receive an indication from the first digital assistant device that the first digital assistant device detected, via a sensor of the first digital assistant device, an input audio signal and that the first digital assistant device is operational to process the input audio signal;
receive an indication from the second digital assistant device that the second digital assistant device detected, via a sensor of the second digital assistant device, the input audio signal and that the second digital assistant device is operational to process the input audio signal;
select, based on the first digital assistant device set as the primary signal processor, the first digital assistant device to process the input audio signal, wherein both the first digital assistant device and the second digital assistant device are operational to process the input audio signal;
instruct, responsive to selection of the first digital assistant device set as the primary signal processor, the first digital assistant device to process the input audio signal; and
instruct, responsive to the second digital assistant set as the secondary signal processor, the second digital assistant device to enter a standby mode to prevent the second digital assistant device from processing the input audio signal.
