1. A speech processing apparatus comprising: a recognition feature information extracting unit which extracts recognition feature information having a characteristic of recognition result data obtained by performing a speech recognition process on an inputted speech, from said recognition result data, said recognition feature information being speech recognition result data for learning which includes plural recognition hypotheses; a language feature information extracting unit which extracts language feature information having a characteristic of a pre-registered language resource from said pre-registered language resource, said pre-registered language resource including document data, sentences, text data, word sequences, or dictionaries, the extracted language feature information including linguistic characteristics included in an existing word sequence, or importance of similarity of a document; and a verification model obtaining unit which obtains a verification model by a learning process based on the extracted recognition feature information and language feature information, the obtained verification model being used to verify a speech recognition result data which is inputted as a verification target to a speech recognition system, wherein said verification model obtaining unit obtains a discriminative model as said verification model, said discriminative model being indicative of a correct and false label or degree of importance according to use.
