Abstract
A method may receive a first audio signal data at a first device, the first audio signal data decoded using a microphone array. A method may determine that the first audio signal data includes an audio sequence relating to an information sharing request. A method may send a first signal. A method may receive a second signal via the microphone array responsive to the first signal. A method may verify that the second signal was sent from a direction of a voice associated with the audio sequence, the second signal including a second device identifier associated with a second device. A method may establish a wireless connection with the second device using the second device identifier.

(canceled)
A method comprising:
- receiving audio data including an audio sequence associated with a device;
- determining that the audio sequence includes a first identifier;
- receiving a signal including a second identifier;
- determining that the second identifier corresponds to the first identifier;
- and
- in response to determining that the first identifier corresponds to the second identifier:
- establishing a wireless connection with the device using the second identifier, and
- using the wireless connection to exchange information with the device.
A system comprising:
- a processor;
- and
- a memory configured with instructions to:
- receive audio data including an audio sequence associated with a device;
- determine that the audio sequence includes a first identifier;
- receive a signal including a second identifier;
- determine that the second identifier corresponds to the first identifier;
- and
- in response to determining that the first identifier corresponds to the second identifier:
- establish a wireless connection with the device using the second identifier, and
- use the wireless connection to exchange information with the device.
A non-transitory computer readable medium storing executable instructions that, when executed by a processor, cause a computing device to:
- receive audio data including an audio sequence associated with a device;
- determine that the audio sequence includes a first identifier;
- receive a signal including a second identifier;
- determine that the second identifier corresponds to the first identifier;
- and
- in response to determining that the first identifier corresponds to the second identifier:
- establish a wireless connection with the device using the second identifier, and
- use the wireless connection to exchange information with the device.
