—An effective multipitch tracking algorithm for noisy speech is critical for acoustic signal processing. However, the performance of existing algorithms is not satisfactory. In this paper, we present a robust algorithm for multipitch tracking of noisy speech. Our approach integrates an improved channel and peak selection method, a new method for extracting(More)
—Under noise-free conditions, the quality of rever-berant speech is dependent on two distinct perceptual components: coloration and long-term reverberation. They correspond to two physical variables: signal-to-reverberant energy ratio (SRR) and reverberation time, respectively. Inspired by this observation, we propose a two-stage reverberant speech(More)
Reverberation corrupts harmonic structure in voiced speech. We observet hat the pitch strength of voiced speech segments is indicative of the degree of reverberation. Consequently,wepresent an estimation method of reverberation time (T 60)based on pitch strength. The pitch strength is measured by deriving the statistics of relative time lags, defined as the(More)
Game refinement is a unique theory that has been used as a reliable tool for measuring the attractiveness and sophistication of the games considered. The refinement measures were derived from game information progress model and have been applied in various types of games. This paper focuses on the game refinement theory and its application to a MOBA game "(More)
Previous research showed that different cultures play a significant role in influencing people's perception and cognition: Eastern people attend more to the background and context, whereas western people focus more on objects. However, the culture influence on people's aesthetic perception and experience has not been systematically explored. In the first(More)
