Device leadership negotiation among voice interface devices
The various implementations described herein include methods and systems for determining device leadership among voice interface devices. In one aspect, a method is performed at a first electronic device of a plurality of electronic devices, each having microphones, a speaker, processors, and memory storing programs for execution by the processors. The first device detects a voice input. It determines a device state and a relevance of the voice input. It identifies a subset of electronic devices from the plurality to which the voice input is relevant. In accordance with a determination that the subset includes the first device, the first device determines a first score of a criterion associated with the voice input and receives second scores of the criterion from other devices in the subset. In accordance with a determination that the first score is higher than the second scores, the first device responds to the detected input.
1. A method performed at a first electronic device of a plurality of electronic devices, each of the plurality of electronic devices comprising one or more microphones, one or more processors, and memory storing one or more programs for execution by the one or more processors, the method comprising:
detecting a voice input from a user;
determining a first value associated with the voice input;
receiving second values associated with the voice input from other electronic devices of the plurality of electronic devices; and
in accordance with a determination that the first value is higher than the second values, responding to the detected input.
2. The method of claim 1 , further comprising:
in accordance with a determination that the first value is not higher than the second scores, forgoing responding to the detected input.
3. The method of claim 2 , wherein forgoing responding to the detected input further comprises changing a state of operation of the first electronic device.
4. The method of claim 1 , further comprising:
in accordance with a determination that the first value is not higher than the second values, identifying a criterion associated with the voice input; and
in accordance with a determination that the criterion is the most relevant to the first electronic device, responding to the detected input.
5. The method of claim 4 , further comprising:
determining a state of the first electronic device;
wherein the determination that the criterion is the most relevant to the first electronic device is based on the state of the electronic device.
6. The method of claim 4 , wherein the criterion comprises one or more of: a type of request, a command in the voice input, and a state of each electronic device of the plurality of electronic devices.
7. The method of claim 1 , further comprising:
at the first electronic device:
detecting subsequent voice inputs from the user;
pre-processing the subsequent voice inputs; and
transmitting the pre-processed voice inputs to a server system;
wherein the other electronic devices forgo the detecting, pre-processing, and transmitting.
8. The method of claim 1 , wherein responding to the detected input comprises outputting an audible and/or a visual response to the detected voice input.
9. The method of claim 1 , wherein the first electronic device further comprises a speaker, and responding to the detected input further comprises outputting an audible response.
10. A first electronic device of a plurality of electronic devices, the first electronic device comprising:
one or more microphones;
one or more processors; and
memory storing one or more programs to be executed by the one or more processors, the one or more programs comprising instructions for:
detecting a voice input from a user;
determining a first value associated with the voice input;
receiving second values associated with the voice input from other electronic devices of the plurality of electronic devices; and
in accordance with a determination that the first value is higher than the second values, responding to the detected input.
11. The first electronic device of claim 10 , the one or more programs further comprising instructions for:
recognizing a command in the voice input; and
in accordance with a determination that a type of the command is related to the first electronic device, responding to the detected voice input.
12. The first electronic device of claim 10 , the one or more programs further comprising instructions for:
communicating to the other devices of the plurality of electronic devices to forgo responding to the detected output.
13. The first electronic device of claim 10 , wherein the instruction for detecting the voice input is performed at intervals of a predefined number of voice inputs.
14. The first electronic device of claim 10 , wherein:
the plurality of electronic devices is communicatively coupled through a local network; and
the receiving is performed through the local network.
15. The first electronic device of claim 10 , wherein the first electronic device is configured to be awakened by a plurality of affordances including a voice-based affordance; and
wherein detecting the voice input is in response to the awakening of the first electronic device.
16. A system comprising a plurality of electronic devices, each of the electronic devices including one or more microphones, one or more processors, and memory storing one or more programs for execution by the one or more processors, each of the electronic devices programmed to:
detect a voice input;
determine a first value associated with the detected voice input;
receive respective second values from other electronic devices of the plurality of electronic devices;
compare the first value and the respective second values; and
in accordance with a determination that the first value is higher than the respective second values, respond to the voice input.
17. The system of claim 16 , wherein the first value comprises a first quality score of the voice input.
18. The system of claim 17 , wherein the first quality score comprises a confidence level of detection of the voice input.
19. The system of claim 17 , wherein the first quality score comprises a signal-to-noise rating of detection of the voice input.
20. The system of claim 16 , wherein each of the respective second values is indicative of a quality of the voice input detected by a respective one of the other electronic devices.
