The application discloses a sound perception-based electronic pet behavior triggering method, and relates to the technical field of intelligent interaction.The method comprises the following steps: collecting environmental sound signals through a microphone array and constructing a sound feature vector, determining sound intensity levels, sound source directions, and user voice classes, environmental event sound classes, and third-party biological sound classes; analyzing different sound classes to obtain user instruction intentions, user emotion labels, and sound event types; dynamically updating in combination with current emotion parameters and energy parameters of the electronic pet; generating priority behavior instructions based on the above information and sending the priority behavior instructions to an action execution module; and monitoring the short-term energy of the electronic pet in real time during the execution process and performing self-noise control.The technical problems of single sound processing, rigid state updating, serious self-noise interference, and lack of continuity of behavior response in the life state of the existing electronic pet are solved.

The application provides a three-dimensional virtual surround sound generation method and generation system, and relates to the field of surround sound. The application adopts an excellent structure of a howling elimination technology to eliminate howling, enhance spatial positioning and speech clarity. Reflection sound is constructed by infinite N-level echo simulation to construct a surround sound channel, so that the generated surround sound has more distant background sound, thereby making the virtual surround sound have strong spatial sense, distance sense, diffusivity and surrounding sense, rather than just positioning sense. A post sound channel is constructed by inversely superimposing the delayed signal on the direct signal, so that the spatial sense of the surround sound is obviously enhanced, and the sound seems to come from all directions. The original sound bass is preserved by separation technology, and the virtual sound in each direction is freely controlled, thereby controlling the sound intensity, tone brightness and tone softness.

The application discloses a snoring sound detection method and device, the method comprising: acquiring a human body sensing signal and an audio signal; determining a device usage state and an audio feature based on the human body sensing signal and the audio signal; selecting a corresponding feature combination based on the human body sensing signal, the device usage state and the audio feature, and inputting the corresponding feature combination into a preset snoring sound detection model for snoring sound detection to determine a current snoring sound state; if the current snoring sound state is determined, determining an initial snoring sound attribution probability based on a preset sound intensity coefficient reference table, a sound phase coefficient reference table and the audio feature, and performing weighted summation on the initial snoring sound attribution probability and the device usage state to determine a final snoring sound attribution result. The application effectively solves the technical defects that snoring sound attribution cannot be determined, detection accuracy is insufficient, and there is a lack of scientific benchmark reference system and probability calculation logic in the process of snoring sound detection in a multi-person cohabitation scene, and effectively improves detection and attribution judgment accuracy.

This application provides a channel configuration method, electronic device, and system, relating to the field of terminal technology. The technical solution provided in this application allows a first electronic device to adaptively configure a channel based on the sound intensity of a first sound and the second sound intensity reported by a second electronic device, simplifying user operation and improving user experience. The method includes: the first electronic device detecting the user's channel configuration operation, collecting sound and determining the first sound intensity, and then determining the target channel in the channel to be configured based on the first sound intensity; receiving at least one second sound intensity sent by one or more second electronic devices, and determining the target device in the second electronic device based on the second sound intensity; and then matching the determined target channel and target device to complete the channel configuration.
