In this paper, we will describe how to build the spontaneous acoustic model first. In the language model, there are many popular spoken word, particle and expletive in the spontaneous speech, which has great difference with the traditional language model. So, we will adapt a spontaneous speech language model based on the traditional language model in this paper. In the improvement of the spontaneous speech prosody model, this paper will re-define the special prosodic phenomena of the spontaneous speech. In addition, people usually use the acoustic model and the language model in the traditional speech recognition. However, there are many differences between read-speech and spontaneous speech. So, this paper will try to use some prosodic information to help the speech recognition and wish to resolve these situations.
