Portable electroglottograph speech collecting device for far-field human-computer interaction

Abstract

The invention discloses a portable electroglottograph speech collecting device for far-field human-computer interaction. In far-field speech human-computer interaction, through the complex combinationof software and hardware and an artificial intelligence algorithm, the effects of background noise, reverberation, echo and the like can be effectively solved in a complex environment. Glottal excitation information is obtained by using electroglottograph, thus a target speech is separated, the noise influence during a transmission process can be effectively removed, and the interference betweendifferent kinds of information is removed. The portable electroglottograph speech collecting device comprises a signal collecting portion, a signal processing portion and a signal transmitting portion. The electroglottograph speech collecting device of the invention has a simple structure and is convenient to carry, high-frequency weak voltage is used, the signal acquisition is more accurate, thedevice can cooperate with other devices, speech features can be extracted well, the influence of noise on a speech when the speed is transmitted in the air is reduced or avoided, and the portable electroglottograph speech collecting device has high detection accuracy and wide application.

Description

technical field [0001] The invention belongs to the field of far-field voice human-computer interaction, and in particular relates to a portable electroglottic voice collection device. Background technique [0002] Far-field voice is a function that combines AI voice search to change user experience. Users who have used Bluetooth voice remote control know that when we want to trigger voice commands, we need to press the voice button on the remote control and say to the remote control In order to make the smart TV or smart box respond, the smart far-field voice function omits the procedure of "pressing the remote control voice key", you only need to sit on the sofa and speak the command Effective within 5 meters), you can get feedback. [0003] In the far-field voice human-computer interaction, how to easily wake up the device with voice in a complex environment has become an extremely important user experience. Far-field speech recognition requires a combination of front-e...

AI Technical Summary

Problems solved by technology

[0005] At present, there are a lot of voice data acquisition devices based on electronic and computer technology on the market, but these products have few specific characteristic parameters, and there are many factors affecting human-computer interaction of far-field voice, so these products cannot comprehensively solve the problem of remote control. The problem of field voice human-computer interaction

In addition, the existing electroglottograph lacks humanized design, and the overly complicated operation and panel design increase obstacles for users. At the same time, the electroglottograph is bulky and heavy, and cannot collect voice signals anytime and anywhere
