Patent ID: 7299178

Claim:
A continuous speech recognition method comprising: (a) constructing a pronunciation dictionary database including at least one pronunciation representation for each word which is influenced by applying phonological rules, wherein the pronunciation representation for the coda of a first word or the pronunciation representation for the onset of a second word following the first word is additionally indexed with an identifier if it does not match the phonetic pronunciation of its spelling; (b) forming inter-word phonetic information in matrix form by combination of a number of all probable phonetic pairs, each of which is basically comprised of the coda of a first word and the onset of a second word following the first word, wherein the coda of the first word or the onset of the second word is indexed with an identifier if they undergo phonological changes; and (c) performing speech recognition on feature vectors extracted from an input speech signal with reference to the pronunciation dictionary database and the inter-word phonetic information.
