The number of audio-sensing-related applications is growing rapidly, such as the voice assistant as an interface between humans and computers, and the automatic-speaker verification system, which involves personal identity. These applications demand reliability and security of the audio sensing system. For example, an audio recognition system can easily get confused by the sound of non-target objects, as everything is fused in the collected audio. Meanwhile, a speaker verification system may fai
