Embodiment Construction
[0018] In order for those skilled in the art to better understand the technical solution of the present invention, a wake-up response method for a voice recognition device, a voice recognition device, and a computer storage medium provided in this application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. describe.
[0019] The wake-up response method of this application is applied to the situation where multiple voice recognition devices can respond to the same voice signal. In this case, taking the field of home appliances as an example, there are multiple home appliances in the same area or in multiple adjacent areas. Household electrical appliances all have a voice recognition function, that is, as a voice recognition device. For example, there are voice recognition devices such as TV sets, air conditioners, and refrigerators in the living room area; voice recognition devices such as refrigerators, microwav...

The invention discloses a voice recognition device and a wake-up response method thereof. A plurality of voice recognition devices form a regional network, and the plurality of voice recognition devices are divided into one central device and at least one non-central device. The wake-up response method comprises the steps of: enabling the central device to analyze a collected voice signal to obtain distance information of the central device, wherein the distance information of the central device represents the distance between the central device and the signal source of the voice signal; receiving distance information of the non-central device, the distance information of the non-central device being obtained by analyzing the acquired voice signal by the non-central device and representinga distance between the non-central device and the signal source; comparing the distance information of the central device with the distance information of the non-central device; and determining to-be-responded voice recognition equipment, wherein the to-be-responded voice recognition equipment is voice recognition equipment responding to the voice signal in the regional network. According to thewake-up response method, one of a plurality of voice recognition devices capable of responding to the voice signal can be determined to respond to the voice signal.
Description
technical field [0001] The present application relates to the field of voice wake-up, in particular to a voice recognition device, a wake-up response method thereof, and a computer storage medium. Background technique [0002] Speech recognition, voice interaction and other technologies have been applied in many fields. Generally, devices equipped with a speech recognition system will wake up when receiving a voice signal and then respond to the voice signal. [0003] For multiple speech recognition devices in the same area, there may be situations where they are simultaneously awakened and responded to by voice signals, but in general application scenarios, the user obviously only wakes up one speech recognition device, and multiple speech recognition devices Waking up and responding at the same time will cause the problem of mutual interference between multiple voice recognition devices. For example, the sound broadcast by one voice recognition device in response to the vo...
