Abstract:     A speech recognition apparatus and the method thereof for correctly recognizing an English word from a non-native English pronunciation, for example. A vector data generating part and a label generating part processes speech data of a sentence of English speech pronounced by a Japanese speaker to convert it to a label string. A candidate word generating part correlates the label string of the sentence to a first candidate word comprising one or more English words. An analogous word adding part uses a word database to search an English word analogous the pronunciation of the first candidate word, such as a analogous word "lead" for a first candidate word "read", for example, (it is difficult for a Japanese speaker to discriminate between "l" and "r" in pronunciation), and adds the obtained analogous word to the first candidate word to make it be a second candidate word. A selection part selects one of the second candidate words as a final result of recognition in response to users operation and connects the selected words into English text data for output.

First Claim:

What is claimed is:     1. A speech recognition apparatus for recognizing words from speech data representing one or more words contained in speech, comprising:
  • candidate word correlating means for correlating each of one or more speech data items of words to one or more sets of candidates comprising a combination of one or more of said words obtained by recognizing each of one or more of said speech data items, the one or more of said words obtained by recognizing each of one or more of said speech data items being candidate words;
  • analogous word correlating means for correlating each of said candidate words correlated to each of one or more of the speech data items of said words to null or more sets of a combination of one or more of said words which may correspond to a pronunciation of each of said candidate words, the one or more of said words which may correspond to a pronunciation of each of said candidate words being analogous words; and
  • speech data recognition means for selecting either said candidate word correlated to each of one or more of said speech data items of words or said analogous word correlated to each of said candidate words as a recognition of each of said speech data items of words.
