Abstract
A speech recognition apparatus of the present disclosure includes: a transforming unit that transforms an utterance by an utterer into a feature vector; a weighting unit that weights the feature vector with importance of the utterance based on situation information representing a situation at time of the utterance by the utterer; and a recognizing unit that recognizes a new utterance by the utterer based on the weighted feature vector.
Claims17
A speech recognition apparatus comprising:
- at least one memory storing processing instructions;
- and
- at least one processor configured to execute the processing instructions to:
- transform an utterance by an utterer into a feature vector;
- weight the feature vector with importance of the utterance based on situation information representing a situation at time of the utterance by the utterer;
- and
- recognize a new utterance by the utterer based on the weighted feature vector.
A speech recognition method comprising:
- transforming an utterance by an utterer into a feature vector;
- weighting the feature vector with importance of the utterance based on situation information representing a situation at time of the utterance by the utterer;
- and
- recognizing a new utterance by the utterer based on the weighted feature vector.
A non-transitory computer-readable storage medium storing a program, the program comprising instructions for causing a computer to execute processes to:
- transform an utterance by an utterer into a feature vector;
- weight the feature vector with importance of the utterance based on situation information representing a situation at time of the utterance by the utterer;
- and
- recognize a new utterance by the utterer based on the weighted feature vector.
