ABSTRACT	We have extended our previous work on isolated digit recognition by applying Sparse Classification to continuous digit recognition. The non-parametric technique is based on the idea that arbitrary speech signals can be represented as a linear combination of suitably selected exemplars. The classification is based on finding the smallest number of labeled exemplars in a very large library of exemplars that jointly approximate the observed speech token. We applied a sliding time window approach by applying SC to every window individually and decoding the utterance using Viterbi decoding. We show that our method outperforms KNN.	user correction
