Short-time Viterbi for online HMM decoding : evaluation on a real-time phone recognition task
Résumé
In this paper we present the implementation of an online HMM decoding process. The algorithm derives an online version of the Viterbi algorithm on successive variable length windows, iteratively storing portions of the optimal state path. We explicit the relation between the hidden layer's topology and the applicability and performance prediction of the algorithm. We evaluate the validity and performance of the algorithm on a phone recognition task on a database of continuous speech from a native French speaker. We specifically study the latency-accuracy performance of the algorithm.
