ESCA Tutorial and Research Workshop on
Organisation and access procedure with reference to a specific ASR system for a large lexicon-consisting of 20,000 phonetic words in Standard Bengali language is described. The lexicon forms a part of a lexical expert sub-system and is required to provide disambiguation advice in addition to verification of word hypothesis. A forest of ambiguity driven binary trees, representing the cohorts of a manner-based word are accessed by a manner-based tree. The ambiguity trees are organised to provide recognition advice for best recognition score. Previous knowledge of vowel and consonant recognition for the particular language has been used in designing ambiguity trees.
