Modeling time series has practical applications in many domains : speech, gesture and handwriting recognition, synthesis of realistic character animations etc...The starting point of our modeling is that an important part of the variability between observation sequences may be the consequence of a few contextual variables that remain fixed all along a sequence or that vary slowly with time. For instance a sentence may be uttered quite differently according to the speaker emotion, a gesture may have more amplitude depending on the height of the performer etc... Such a variability cannot always be removed through preprocessing.We first propose the generative framework of Contextual Hidden Markov Models (CHMM) to model directly the influence ...
