Structured language modeling
This paper presents an attempt at using the syntactic structure in natural language for improved language models for speech recognition. The structured language model merges techniques in automatic parsing and language modeling using an original probabilistic parameterization of a shift-reduce parser. A maximum likelihood re-estimation procedure belonging to the class of expectation-maximizatio...
متن کاملStructured Language Modeling Forspeech
We present revised Wall Street Journal (WSJ) lattice rescoring experiments using the structured language model (SLM). 1 Experiments We repeated the WSJ lattice rescoring experiments reported in 1] in a standard setup. We chose to work on the DARPA'93 evaluation HUB1 test set | 213 utterances, 3446 words. The 20kwds open vocabulary and baseline 3-gram model are the standard ones provided by NIST...
متن کاملEfficient Structured Language Modeling for Speech Recognition
The structured language model (SLM) of [1] was one of the first to successfully integrate syntactic structure into language models. We extend the SLM framework in two new directions. First, we propose a new syntactic hierarchical interpolation that improves over previous approaches. Second, we develop a general information-theoretic algorithm for pruning the underlying Jelinek-Mercer interpolat...

two simple methods of enriching the dependencies in the syntactic parse trees used for intializing the structured language model (SLM) achieve improvement in perplexity (PPL) and word-error-rate (WER, N-best rescoring) over the baseline results reported using the SLM on the UPenn Treebank and Wall Street Journal (WSJ) corpora, respectively Structured Language Model ✔Generalize trigram modeling ...
متن کاملStructured Language Modeling for Speech Recognition
A new language model for speech recognition is presented. The model develops hidden hierarchical syntactic-like structure incrementally and uses it to extract meaningful information from the word history, thus complementing the locality of currently used trigram models. The structured language model (SLM) and its performance in a two-pass speech recognizer — lattice decoding — are presented. Ex...
