Abstract
A method for processing and responding to audio input signals includes receiving, at a first device, an audio input signal having a trigger prompt. At the first device, the audio input signal is processed to determine a first quality metric of the audio input signal. The first device transmits the first quality metric over a local network and monitors whether a higher second quality metric of the audio input signal is transmitted by a second device over the local network. If a higher second quality metric is not received by the first device, by the first device responds to the trigger prompt.
Claims20
A computer-implemented method comprising:
- receiving at a first device an audio input signal comprising a trigger prompt;
- processing at the first device the audio input signal to determine a first quality metric of the audio input signal;
- transmitting by the first device the first quality metric over a local network;
- monitoring by the first device whether a higher second quality metric of the audio input signal is transmitted by a second device over the local network;
- and
- if a higher second quality metric is not received by the first device, responding by the first device to the trigger prompt.
A computer device comprising:
- a processor;
- an input/output interface;
- a microphone;
- and
- a network interface,
- wherein the processor is configured to:
- receive an audio input signal comprising a trigger prompt via the microphone and input/output interface;
- process the audio input signal to determine a first quality metric of the audio input signal;
- transmit via the network interface the first quality metric to a local network;
- monitor via the network interface whether a higher second quality metric of the audio input signal is transmitted by another device to the local network;
- and
- if a higher second quality metric is not received, respond to the trigger prompt.
A computer program comprising instructions for causing a processor of a first computer device to:
- receive an audio input signal comprising a trigger prompt;
- process the audio input signal to determine a first quality metric of the audio input signal;
- transmit the first quality metric over a local network;
- monitor whether a higher second quality metric of the audio input signal is transmitted by a second computer device over the local network;
- and
- if a higher second quality metric is not received, respond to the trigger prompt.
