✦ Synopsis
In this paper, we propose the use of a tree-trellis search scheme for the task of large vocabulary Mandarin polysyllabic word recognition. Usually, the task of large vocabulary word recognition is computationally intractable by whole-word based approach. We convert this task into a tree network search problem by considering basic syllables as matching units. A vocabulary of 22088 polysyllabic words is represented by a tree network linked with basic syllables. Some implementations of tree-trellis search scheme for this special task are investigated. In comparison with other search algorithms, the experimental results show that the tree-trellis search algorithm is a very promising one for this special task.
