Query: Disappeared Command: Spoofing Attack On Automatic Speech Recognition
  Systems with Sound Masking   The development of deep learning technology has greatly promoted the
performance improvement of automatic speech recognition (ASR) technology, which
has demonstrated an ability comparable to human hearing in many tasks. Voice
interfaces are becoming more and more widely used as input for many
applications and smart devices. However, existing research has shown that DNN
is easily disturbed by slight disturbances and makes false recognition, which
is extremely dangerous for intelligent voice applications controlled by voice.
