Abstract(in English) | This paper describes a Viterbi search algorithm for continuous speech recognition using context-dependent phone models under the constraint defined by a context-free grammar (CFG). It is based on a frame synchronous LR parser which dynamically generates a finite state network (FSN) from the CFG with an efficient path merging mechanism. Full context-dependency (intra- and inter-word context) is taken into account. This paper first describes the algorithm and the processing mechanism, then compares the experimental results of our algorithm and the conventional tree-based HMM-LR speech recognition algorithm which uses HMMs and an LR parser in phone-synchronous processing. The experiments show that our algorithm runs faster than the HMM-LR algorithm with an equivalent recognition accuracy. |
