Abstract
This speech recognition device is provided with: an acceptance unit that accepts input of speech information; a parameter storage unit that stores a plurality of parameters for setting a speech recognition model; a temporary setting parameter selection unit that selects, on the basis of narrowing information, a temporary setting parameter to be temporarily set, from the plurality of parameters; a recognition unit that recognizes speech information on the basis of the selected temporary setting parameter; and a parameter selection unit that selects, on the basis of information indicating a recognition result of the recognized speech information, one of the temporary setting parameters.
Claims10
A speech recognition device, comprising:
- at least one processor;
- and
- a memory storing a program executed by the at least one processor, wherein
- the memory stores a plurality of parameters for setting a speech recognition model of speech recognition models,
- the at least one processor is configured to:
- accept input of speech information,
- acquire the plurality of parameters for setting the speech recognition model from the memory,
- select, from the plurality of parameters, a plurality of temporary setting parameters to be temporarily set, based on narrowed information,
- perform recognition processing on the speech information using the speech recognition models respectively corresponding to the plurality of temporary setting parameters, and obtain a plurality of recognition results,
- finally determine one setting parameter from among the plurality of temporary setting parameters based on reliability of the plurality of recognition results, and
- perform subsequent recognition processing based on the finally determined one setting parameter, and
- the plurality of parameters includes at least either a plurality of acoustic setting parameters for setting an acoustic model, or a plurality of grammar setting parameters for setting a grammar model.
