Abstract (in Japanese) (See Japanese page) 
(in English) Machine learning technology has improved the recognition accuracy of voice recognition, and demand for voice recognition systems, including smart speakers and voice assistants, are growing.
On the other hand, there is a concern that voice recognition systems are vulnerable in terms of security.
In particular, the Audio Adversarial Example, which is a vulnerability of machine learning technology and causes false recognition in speech recognition systems, has become a problem. In this paper, we propose a method to protect the speech recognition system from the Audio Adversarial Example attack by using speech processing.
The proposed method aims to prevent misrecognition by processing the input speech with a small amount of processing that does not affect the recognition of normal speech.
In this paper, two processing methods, frequency processing and speed processing, are used for verification.
The evaluation results show that the proposed method can reduce the attack success rate of the attacked speech to 0% while minimizing the effect on the recognition rate of normal speech.
