Method for statistical language modeling in speech recognition

摘要

A system for generating language modeling data for a speech recognition system includes an expression extractor to extract expression from domain-specific data of an existing domain using a base of linguistic knowledge, a concept structure mapper to map extracted expression to expression in a new domain using vocabulary for the new domain, a concatenation module to concatenate extracted expression with domain-general data, and a filter arrangement to identify and filter out unrealistic expression in the mapped or concatenated expression.
