Speech communication with emotions is therefore indispensable to develope more human-friendly applications. To achieve such an emotion-based speech communication system, we set the goal of our study to establish a kansei-based brain-machine interface (BMI) using speech, through which the brain information on emotions controls devices, robots, etc. Here, we consider \"emotion\" as one form of \"kansei\" or affect. As an element of such a BMI, this paper proposes a rule-based Japanese speech synthesis system that is capable of expressing variable degrees of emotions based on prosody as well as voice-quality conversion. Among voice-quality features, we find that a spectral feature called \"the spectral tilt\" that expresses the degree of empasis of the higher-frequency band depends on the type and degree of emotion. From our previous analyses, we found that the spectral-tilt quantities increased as the degrees of \"anger \" , \"joy \" , and \"crying-type (hot) sadness \" increased. On the other hand, the spectral-tilt quantities were found to decrease as the degree of \"dispirited-and-whispering-type (cold) sadness \" increased. We formulate a transfer function that converts spectral-tilt quantities of \"neutral\" speech to those of emotional speech in various degrees, and introduce this spectral-tilt conversion rule into our speech-synthesis system. The prosody-conversion rules are also determined based on our previous findings. Informal listening to \"hot anger\" and \"cold sadness\" synthetic-speech samples converted by the proposed method gives us impressions of those similar to natural emotional speech and the differences depending on the degrees of emotions are recognizable.","subitem_description_type":"Abstract"}]},"item_2_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"本研究は近畿大学生物理工学部戦略的研究No,10-IV-25,
