Bayesian Learning of a Language Model from Continuous Speech

Graham NEUBIG, Masato MIMURA, Shinsuke MORI, Tatsuya KAWAHARA
2012 IEICE transactions on information and systems  
Implementation is performed using weighted finite state transducers (WFSTs), which allow for the simple handling of lattice input.  ...  We propose a novel scheme to learn a language model (LM) for automatic speech recognition (ASR) directly from continuous speech.  ...  This is done by first creating a WFST-based formulation of the WS model (Sect. 4.1), then describing a dynamic programming method for sampling over WFSTs (Sect. 4.2).  ...
