Lipreading HLM and Text Flow Analysis
唇读中的HLM模型及其文字流解析

Since lip movement sequence and language sequence are one-to-many mapping,it is far from sufficiency to use only HMM for lip-reading recognition.Proposed a novel recognition model HLM(HMM and Bigram Language Model),which is based on HMM,and combined with prior knowledge of language.In contrary to the traditional framework,which adopts pure acoustic HMM posterior probability calculation for recognition,HLM combines closely language background knowledge and HMM.It carries on background knowledge of the langua...
