no. 1 Embodiment

[0046] Preferably, as the first specific embodiment of the dual-microphone noise cancellation implementation method of the present invention, the step S100 specifically includes:

[0047] Step S111: Obtain the first sound source voice signal from the first microphone, and input it into the first differential amplifier connected to the first microphone to obtain the first sound source differential amplified signal; obtain the first environmental noise signal from the first microphone and input it to The first differential amplifier connected to the first microphone obtains the first noise differential amplified signal.

[0048] Step S112: Obtain the second sound source voice signal from the second microphone, and input it into the second differential amplifier connected to the second microphone to obtain the second sound source differential amplified signal; obtain the first environmental noise signal from the second microphone and input it to The second differential amplifier conne...

Abstract

The invention discloses a double-microphone noise elimination implementation method and system and smart glasses. The method comprises the steps that a first sound input signal is acquired by a first microphone arranged on the frame of the smart glasses, and a second sound input signal is acquired by a second microphone arranged at the rear end of the leg of the smart glasses; and the sound signal of a sound generating source is acquired by the difference of the first sound input signal and the second sound input signal. The sound signal of the sound generating source is acquired by the difference of the sound input signals acquired by the double microphones so that the interference influence of environmental noise can be effectively suppressed and the recognition accuracy can be enhanced.

Description

Technical field [0001] The invention relates to the technical field of smart wearable equipment, and in particular to a method, system and smart glasses for implementing dual-microphone noise cancellation. Background technique [0002] With the rapid development of smart wearable devices, smart wearable devices are becoming more and more popular among people, and they are increasingly an indispensable part of life, bringing a lot of convenience to people's lives. [0003] Smart wearable devices are generally worn on the body, like smart glasses. People wear smart glasses for work, outdoor activities, biking, driving, etc. Wearable devices spend more time working in the surrounding noisy environment. The voice recognition belt of smart wear It is extremely difficult, that is, the accuracy of recognition is reduced due to the influence of surrounding noise. [0004] Therefore, the existing technology needs to be improved and developed. Summary of the invention [0005] In view of the ...
