The posteriors from the two models are interpolated using equal weights. The SRI-LM toolkit =-=[14]-=- (with Kneser-Ney smoothing) is used for training the hidden-event model for sentence boundary prediction, with the same data sources as for training the Mandarin ASR language models, including broadc...
