Several approaches to speech and auditory systems for human system interactions

In the human communication, auditory and speech functions play an important role for recognizing someone to talk to and understanding the conversations. Various vocal sounds are generated by the complex movements of speaker´s vocal organs, and this mechanism contributes to generate different voices that include speech expressions and speaker´s individuality. This paper introduces several approaches to speech and auditory systems for introducing flexible interactions between humans and systems, which have been constructed by the authors.
