In this paper, we present a statistical parametric speech synthesis system based on the polynomial segment model (PSM). As one of the segmental models for speech signals, PSM explicitly describes the trajectory of the features in a speech segment, and keeps the internal dynamics of the segment. In this work, spectral and excitation parameters are modeled by(More)
Efficient solution of the single source shortest path (SSSP) problem on road networks is an important requirement for numerous real-world applications. This paper introduces an algorithm for the SSSP problem using compression method. Owning to precomputing and storing all-pairs shortest path (APSP), the process of solving SSSP problem is a simple lookup of(More)
