PURPOSE:To save the labor for operation by executing automatically a noise inspection while comparing the output of a speech output device with a reference pattern under computer control for frequencies at several points within a band. CONSTITUTION:The inspection system consists of an oscillator 4 which supplies various test frequencies to the speech output device, speech recognizing device 12 which detects a noise, and a control computer 1 which is stored with the procedure of the noise inspection, etc. Then, the speech recognizing device 12 compares a speech output signal 7 of frequency f1 sent from the oscillator 4 through the speech output device 2 with a previously stored reference pattern of frequency f1 to detect a noise component, and outputs the decision result 10 to the computer 1. Further, the computer 1 stores the result for the frequency f1 and conducts a noise test successively for frequencies f2-fn to output the result to a printer 11. |
