Abstract(in English) | Recently, a learning method of n-gram showing error tendency is focused on. In this method, it is difficult to learn low frequency n-gram appropriately. On the other hand, error detection method for content words was proposed that uses semantic similarity in neighboring recognition result. In this paper, we especially examine semantic score and propose a method for speech recognition error detection that integrates these information. As a result of evaluation experiment using the Corpus of Spontaneous Japanese, error detecting performance was improved for content words in particular. Moreover, semantic score is effectively used by combining with term-weight. |
