1. A speech recognition dictionary compilation assisting system, comprising: a computer processing apparatus; and a computer-readable storage medium having data stored thereon that includes a dictionary, a language model, an acoustic model, and a speech recognition dictionary compilation assisting program that is executable by the computer processing apparatus to cause the computer processing apparatus to operate as: a text analysis section that applies morphological analysis to input text data to produce analyzed text data comprising words of the input text data and pronunciation information for each word; a virtual speech recognition processing section that performs a speech recognition process on said analyzed text data received from the text analysis section by applying the dictionary and the language model to said analyzed text data thereby to generate virtual text data, and that compares a pronunciation information of the virtual text data with the pronunciation information of the analyzed text data to extract and output different points of the analyzed text data and the virtual text data, each different point comprising an element of the analyzed text data and a corresponding element of the virtual text data; and an update processing section that corrects at least one of the dictionary and the language model in accordance with the different points identified by the virtual speech recognition processing section, wherein for each different point, the pronunciation information corresponding to a word of the analyzed text data differs from a corresponding pronunciation information of the virtual text data.
2. The speech recognition dictionary compilation assisting system according to claim 1 , wherein said virtual speech recognition processing section generates a sequence of feature vectors from the analyzed text data, the sequence of feature vectors comprising acoustic parameters as elements, and performs a virtual speech recognition process on the sequence of feature vectors to generate the virtual text data.
