Embodiment Construction

[0033] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] The present invention provides a voice interaction method. When receiving a voice command and performing a voice broadcast on the execution result of the voice command, the voice broadcast parameter is obtained, and the echo cancellation function is selectively activated according to the parameter, so as to reduce computing overhead, reduce power consumption and cost, and improve the intelligence and man-machine interactivity of the voice interaction process, making voice interaction more humane.

[0035] An embodiment of the present invention proposes a voice interaction method.

[0036] refer to figure 1 , figure 1 It is a schematic flowchart of the first ...

Abstract

The invention discloses a voice interaction method, a voice interaction system and a household appliance, wherein the voice interaction method includes receiving a voice command; performing voice broadcast on the execution result of the voice command, and obtaining voice broadcast parameters; and selecting according to the acquired voice broadcast parameters. to activate the echo cancellation function. The present invention selectively activates the echo cancellation function according to the voice broadcast parameters, so as to achieve the technical effect of reducing computing overhead, power consumption and cost, and improves the intelligence and man-machine interactivity of the voice interaction process, making the voice interaction more humanized .

Description

technical field [0001] The invention relates to the field of voice interaction, in particular to a voice interaction method, a voice interaction system and household appliances. Background technique [0002] The current voice interaction technology can be applied to users and household appliances to realize real-time information control of household appliances by users. Usually, the user wakes up the device with a wake-up word, and after speaking the command, the device gives the user feedback on the execution of the command by broadcasting to realize voice interaction. Generally, when the device is broadcasting voice feedback, since the microphone picks up the broadcast voice and the new user command indiscriminately, it cannot respond to the user's new command. Some voice interactive systems use Acoustic Echo Cancellation (AEC, Acoustic Echo Cancellation) technology to weaken or eliminate the broadcast voice, but because the length of the broadcast feedback is unknown and...
