摘要: The authors present an automatic method for modeling phonological variation using decision trees. For each phone they construct a tree that specifies the acoustic realization of as function context in which it appears. Several-thousand sentences from natural language corpus spoken by several speakers are used to these Experimental results on 5000-word vocabulary speech recognition task presented. >
