Title:
CONTINUOUS SENTENCE SPEECH RECOGNITION SYSTEM
Document Type and Number:
Japanese Patent JP3425165
Kind Code:
B2
Abstract:
PURPOSE: To provide the continuous sentence speech recognition system which efficiently recognizes a sentence in consideration of modification relation, semantic relation, and relativity between phrases.
CONSTITUTION: Phrases are classified into phrase groups by cases and meanings and stored in a case ruling grammar table 3. A phrase selection part 2 sets a flag for a phrase group of a phrase group flag 4 which possibly appears in an input speech. A collation part 1 collates the phrase templat 5 of the phrase for which the flag is set with the input speech. The phrase selection part 2 resets the flag once the phrase for which the flag is set appears in the input speech. The result of collation between the phrase in the input speech and the phrase templat is outputted as a recognition score and the continuous input speech is recognized. Further, a beam search branch cutting part 6 is provided to narrow down candidates for phrases and a relativity score calculation part 7 calculates a relativity score to recognize the continuous sentence speech faster and more accurately.
