1. A method comprising:
generating for output, by a first device, a query;
determining a device type of a second device;
generating an inaudible signal at a frequency selected based on the device type;
transmitting, by the first device, the inaudible signal, wherein the inaudible signal comprises: (a) an activation signal; and (b) context data for the query;
wherein the transmitting of the inaudible signal causes the second device to:
activate of the second device based on receipt of the activation signal;
capture a voice response to the query; and
perform an action based on the voice response to the query and the context data for the query.
