A novel strategy for hierarchical speech recognition is proposed
in this paper. Based on space partition, it takes the advantage of
each recognizer on subspace. It organizes recognizers in a
manner of nested recursion. Experiment results show that the
final performance of the new method can reach an error
reduction about 33% compared with the best recognizer.
