Abstract(in English) We describe an attempt to apply the PGLR model to an allophone model in speech recognition. The PGLR model is a stochastic model that returns the probability of each generated parse tree. The PGLR model has the advantage that it si mildly context sensitive and at the same time readily interfaces with information about the connectability of terminal symbol pairs (so called bigrams). The construction of a good stochastic language model is one important task in speech recognition. We built a PGLR parser using a CFG with allophone symbols and compared our model with both allophone-level bigram and trigram models in terms of test-set perplexity.
