PROBLEM TO BE SOLVED: To provide a novel voice processor, a voice clearing device, and a voice processing method which make it easy to hear voice from speakers, even in an existing acoustic device and a broadcasting facility.SOLUTION: Collected audio signals are branched, a low frequency component equal to low-order formant or lower and a high frequency component beyond high-order formant are removed from one of the branched audio signals, a phase of the other audio signal is synthesized with an audio signal corrected so that it matches a phase of the processed audio signal and processed, and outputted. Thus, it is possible to extract from the original audio signal only formant components of second to fourth degree significance for language discrimination, to add it to an original audio signal, and to output it, so that contents of the voice can be clearly heard.SELECTED DRAWING: Figure 5 |
