Voice control intelligent garbage can based on acoustic vector sensor

Abstract

The invention discloses a voice-control intelligent garbage can based on an acoustic vector sensor. The functions of the garbage can such as listening, turning and walking are realized. Listening means identifying simple command words of a user; turning means turning to an estimated azimuth angle where the user is; walking means moving to the front of the user; the voice-control intelligent garbage can belongs to the technical field of voice human-computer interaction. The garbage can is called mini T; when the user needs to throw garbage, the user only needs to say 'come here, mini T', the azimuth angle of the sound voice of the user is estimated after the user command is identified by the mini T, and the user moves towards the user according to the azimuth angle; when the user says 'stop, mini T', the mini T stops moving after the command is identified; the user says 'go back, mini T' after the garbage is thrown, the mini T returns to an original position after the command is identified. The voice control intelligent garbage can provides a friendly voice human-computer interaction mode, and the garbage can is controlled by voice, so that the using requirement for old people, the disabled and pregnant women with mobility difficulties or bedridden patients, and great convenience is brought for the application scenarios such as intelligent home and medical wisdom.

Description

technical field [0001] The present invention relates to a voice-controlled intelligent dustbin based on an acoustic vector sensor (AVS), which involves AVS-based speaker sound source direction angle estimation technology, voice endpoint detection technology and voice recognition technology, belonging to voice human-computer interaction and intelligence. The field of home technology. [0002] When the user wants to throw garbage, just say "Little T, come here", the trash can "hear" the user's call, it will estimate the direction angle of the user, and move towards the user according to this direction angle, when the user says "Little T" When "T stop", the trash can T will recognize the command and stop. When the user finishes throwing away the garbage and say "T goes back", the trash can T will recognize the command and return to the original position. Background technique [0003] With the continuous maturity and innovation of technology, the application of smart technology...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the above-mentioned deficiencies, the object of the present invention is to provide a voice-controlled smart trash can based on AVS. When the user needs to throw away trash, he calls the trash can, and the trash can moves to the user. It is convenient to throw away the garbage in the hands to meet the needs of the elderly, the disabled, pregnant women or bedridden patients with limited mobility
