Abstract

PURPOSE:To stabilize a voicing level and to improve the performance of voice recognition processing, etc. by feeding back level variation more positively by taking advantage of a judgement of the voicing level of a human being based upon the listenable volume of sound. CONSTITUTION:A voice inputted through a microphone 1 is sent to a voice processor 3 through a microphone amplifier 2. The voice signal is supplied to a level monitor part 4 to check the difference of the voice from a mean level, and an amplification degree control signal to a variable amplitude degree amplifier 5. This amplifier 5 amplifies the voice signal or answer voice signal according to the amplification degree control signal and sends out the answer voice signal to drive headphones 6 put on the voicing person. Thus, the voicing level in voice input is stabilized and the performance of voice recognition processing, etc., is improved.

Even if you make adjustments, the vocalization level will gradually become lower or louder. Conventionally, even in such cases, it was necessary to control the vocalization while monitoring the level meter display.

When the input level is high, the response to the headphones is returned louder, allowing the speaker to hear changes in the vocal level.This is because human vocal levels are judged by the volume that can be heard. By taking advantage of this fact and actively feeding back level fluctuations, the generation level can be controlled to a constant level.

The level monitoring section 4 checks the diameter of the audio signal with respect to the average level of the audio, and sends an amplification control signal to the amplification LiTg amplifier 5. The variable amplification amplifier 5 amplifies the voice signal or the response sound signal in accordance with the total amplification control signal, sends out a response voice signal, and drives the headphone 6 of the speaker.
