In this study, we focus on noise reduction from external environment in robot auditory system, and developed noise reduction and parameter tuning method utilizing speech recognition system. The feature of this study is not to tune speech recognition system and noise reduction system independently, but to tune them in a comprehensive way. By integrating noise reduction system and noise reduction system totally, the applicable range of parameter tuning became wide. It is considered that the developed system will be applicable not only to robot auditory but also to car navigation system and biometric identification.
