... number of operations grows linearly with the number of arcs in the decoding network. As the overall number of arcs in the decoding network is a linear function of the number of ares in the ... ambiguity in finding the best matching string. The performance can further be improved if the acoustic matching information used in the recognition process is incorporated in...
