In this paper, we propose a formalism, called vector filtering of spectral trajectories, which allows to integrate under a common formalism a lot of speech parameterization approaches. We then propose a new filtering in this framework, called time-frequency principal components (TFPC) of speech. We apply this new filtering in the framework of speaker(More)
In this paper, we present a new formalism, called vector filtering , which consists in transforming a sequence of vectors through a matricial filtering. This formalism allows us to unify a number of classical approaches. We also show how vector filtering can be integrated in a pattern recognition system. We then propose a new filtering, called contextual(More)
