<p>PROBLEM TO BE SOLVED: To provide a voice processor which enables the input of breaking sounds, booes, etc., other than a voice of word and recognizes those sounds as well as a voice. SOLUTION: The voice processor has a voice input processing means 10 having a gain control function 11, a passing-band adjusting function 12, and an A/D converting function 13, a voice analytic preprocessing means 30 having a spectrum analyzing function 31 of taking a spectrum analysis of a voice, a gain analyzing function 32, a cutoff frequency arithmetic function 33, and a gain arithmetic function 34, a voice recognition processing means 50 having a voice pattern matching processing function 51, an ordinary sound dictionary 52 containing voices of ordinary words, a special sound dictionary 53 containing voices other ordinary words, and a dictionary selecting function 54 which selects the two sound dictionaries, and an alarm generating means 70 having an integrating function 71, a threshold processing function 72, a weight-excitation time table 73, and a communication function 74.</p> |
