GENERATION OF VOICE REFERENCE PATTERN

摘要

PURPOSE: To efficiently generate a standard pattern which matches environment and improve its speech recognition rate by generating the standard pattern by speaking in the environment through an artificial circuit system and putting data which is taken in again in a speech data base including environmental information. CONSTITUTION: The speech spoken by an artificial mouth 4 is sent to a private branch line from a transmitter and put in a line interface 5' through a private branch exchange 5, and an A/D-converted signal is inputted to a minicomputer 1 through a telephone band filter 6 to generate a new speech data base of sampling of 8kHz. A standard pattern generation part 10 generates a new standard pattern from data and labeling data extracted by acoustic analysis and speech recognition matching the environment of the telephone line can be performed. Consequently, the standard pattern for the speech recognition matching the environment can be generated from the speech data base and the recognition rate can be improved.
