We analyzed the prosodic features of “anger,” “joy,” and “sadness” depending on the degree of the emotion for expressions in Japanese speech. The degrees of emotion were “neutral,” “light,” “medium” and “strong.” Four announcers (two male and two female) uttered 6 words five times, and the parameters of the prosodic features were speech rate and fundamental(More)
This paper presents the first proof-of-concept implementation and the principle that realizes a projection display whose contrast does not decrease even with existing inter-reflection of projection light or environmental light. We propose the use of photochromic compounds (PhC) to control reflectance of a projection surface. PhC changes color chemically(More)
We analyzed the prosodic features of “anger,” “joy,” and “sadness” expressions in Noh farce (“Kyohgen”) speech depending on the degree of the emotions. The degrees were divided into the following four categories: “neutral,” “low,” “medium” and “high.” A male Noh comedian uttered 6 words that are phonetically similar with one another five times, and the(More)
We propose a novel inter-reflection compensation technique for immersive projection displays wherein we spatially modulate the reflectance pattern on the screen to improve the compensation performance of conventional methods. As the luminance of light reflected on a projection surface is mathematically represented as the multiplication of the illuminance of(More)
This paper describes the analysis of the voice-quality features of “anger”, “joy”, and “sadness” depending on the degree of the emotion for expressions in Japanese speech. The degrees of emotion were “neutral”, “light”, “medium” and “strong”. Among voice-quality features, we turned to the noise level of the glottal-flow waveform. We adopted the AR model and(More)
