This paper describes how grammar-based language models for speech
recognition systems can be generated from Grammatical Framework (GF)
grammars.  Context-free grammars and finite-state models can be
generated in several formats: GSL, SRGS, JSGF, and HTK SLF.  In
addition, semantic interpretation code can be embedded in the
generated context-free grammars.  This enables rapid development of
portable, multilingual and easily modifiable speech recognition
applications.
