Embodiment Construction

[0045] like figure 1It is shown that the embodiment involves a secure voice interaction system based on smart terminals, including: noise interference module and interference noise self -elimination module, where: noise interference modules and smart terminal playback devices and interference noise self -elimination modules Connect and output interference noise. The interference noise self -elimination module is connected to the collection device and noise interference module of the smart terminal, and the audio is to be collected according to the receiving signal and interference noise extraction.

[0046] The noise interference module includes: user voice collection unit, equipment distortion compensation unit, random voice hybrid unit and multi -speaker beam -shaped unit, where: user voice collection unit is connected to the equipment distortion compensation unit and transmitted collection for synthetic interference. The original voice signal information of the noise, the voice...

Abstract

A secure voice interaction method based on smart terminals, when the audio signal needs to be collected, the interference noise is actively generated by the smart terminal and the audio to be collected is superimposed, and then the smart terminal based on the prior knowledge of the interference noise, adaptively de-noises the received signal and generates noise. Extract the audio to be captured. The invention uses the user's own voice to generate interference noise and effectively self-eliminates under the time-varying channel, can be deployed and used on existing equipment, and ensures the security of voice interaction without affecting the realization of normal voice interaction functions.

Description

Technical field [0001] The present invention involves a technology in the field of information security, which specifically involves a security terminal -based security voice interaction method and system. Background technique [0002] With the rapid popularization of mobile devices, human -computer interaction is also evolving. Voice interaction as a new way of interaction is becoming more and more mature and popular, including voice input methods such as Iflytek and voice assistants such as Googleassistant, Siri, Cortana, etc. However, due to the openness of voice signals, these interactions may face great security threats, and eavesdroppers obtain privacy information through on -site eavesdropping or recording. With the widespread application of voice technology, security issues become more important. Therefore, it is very important to provide strong protection for voice interaction [0003] In existing work, there are already some solutions for similar issues. One type of sol...
