Speech recognition apparatus, speech recognition method, and speech recognition robot |
摘要 |
A speech recognition apparatus includes a speech input unit that receives input speech, a phoneme recognition unit that recognizes phonemes of the input speech and generates a first phoneme sequence representing corrected speech, a matching unit that matches the first phoneme sequence with a second phoneme sequence representing original speech, and a phoneme correcting unit that corrects phonemes of the second phoneme sequence based on the matching result. |

1. A speech recognition apparatus comprising
a storage medium storing a relationship between a recognition reliability and a correct answer rate for every phoneme; and a processor programmed with instructions that, when executed, cause the processor to: receive speech; recognize phonemes of the speech and generate a first phoneme sequence representing corrected speech; match the first phoneme sequence with a second phoneme sequence representing original speech so as to create a pair of a first phoneme extracted from the first phoneme sequence and a second phoneme extracted from the second phoneme sequence; and replace the second phoneme with the first phoneme when the second phoneme differs from the first phoneme, a predetermined recognition reliability of the first phoneme is higher than a predetermined recognition reliability of the second phoneme, and a correct answer rate of the first phoneme determined based on the relationship stored in the storage medium is higher than a predetermined value. |
