Abstract
An extended-word selecting section calculates a score for a phoneme string formed of one or more phonemes, corresponding to the user's voice, and searches a large-vocabulary dictionary for a word having one or more phonemes equal to or similar to those of a phoneme string having a score equal to or higher than a predetermined value. A matching section calculates scores for the word searched for by the extended-word selecting section in addition to a word preliminarily selected by a preliminary word-selecting section. A control section determines a word string serving as the result of recognition of the voice.
Claims7
A voice recognition apparatus for calculating a score indicating a likelihood of a result of voice recognition applied to an input voice and for recognizing the voice according to the score, comprising:
- a detecting part for detecting a phoneme string formed of at least one phoneme corresponding to the voice;
- a searching part for searching for a word having at least one phoneme which is at least similar to the phonemes of the phoneme string;
- a score calculating part for calculating a score at least for the word searched for by the searching part;
- and
- a determination part for determining a word string serving as a result of recognition of the voice according to the score calculated for the word.
A voice recognition method for calculating a score indicating a likelihood of a result of voice recognition applied to an input voice and for recognizing the voice according to the score, the method comprising the steps of:
- detecting a phoneme string formed of at least one phoneme corresponding to the voice;
- searching for a word having at least one phoneme which is at least similar to the phoneme string;
- calculating a score at least for the word searched for in the searching step;
- and
- determining a word string serving as a result of recognition of the voice according to the score calculated for the word.
A recording medium for storing a program which makes a computer execute voice-recognition processing for calculating a score indicating a likelihood of a result of voice recognition applied to an input voice and for recognizing the voice according to the score, the program comprising:
- a detecting step of detecting a phoneme string formed of at least one phoneme corresponding to the voice;
- a searching step of searching for a word having at least one phoneme which is at least similar to the phoneme string;
- a score calculating step of calculating a score at least for the word searched for in the searching step;
- and
