Abstract

The embodiment of the invention provides a device waking up method for an acoustic networking. The method comprises the steps that gain parameters of intelligent voice devices with various types are determined; the intelligent devices under the acoustic networking are monitored, and when the intelligent voice devices are woken by waking up commands, the voice frequency recorded by the intelligent voice devices and the confidence coefficient of the waking up commands are obtained; voice frequency energy recorded correspondingly are analyzed according to the gain parameters to achieve gain calibration, and according to the distance and the direction of all to-be-selected intelligent voice devices and a user, at least the distance and the direction of all the to-be-selected intelligent voice devices and the user, and the confidence coefficient of the waking up commands are input into a pre-trained neural network, and thus information fusion analyzing is conducted, and the intelligent devices for feeding back the user is woken. The embodiment of the invention further provides a device waking up system for the acoustic networking. According to the embodiment, the allocation requirements of intelligent voice in the acoustic networking are lowered, the target acoustic device for feeding back is effectively determined, and the interactive experience of the user is improved.

Description

technical field [0001] The invention relates to the field of intelligent voice interaction, in particular to a device wake-up method and system for acoustic networking. Background technique [0002] With the rapid development of intelligent voice, more and more smart devices with voice interaction function have appeared for users to use. For example, smart speakers, smart TVs, smart story machines, and even more advanced smart desk lamps can use voice. interact. These devices interact with the user after waking up in response to the user's wake-up command. [0003] When users purchase smart voice devices, they will have some "brand beliefs", or they will consider buying smart voice devices of the same brand in order to match existing smart voice devices. Since the wake-up commands of the smart voice devices of the same brand are basically the same, for example, the wake-up commands of these smart voice devices are all "small C small C". When the user sends out the wake-up...
