The arrangement includes a sound memory for recording speech instructions, a noise level detector for detecting the level of an environment noise which is entered through a microphone, a control mechanism for determining the speech recognition level according to the detected noise level, and a speech instruction recognition processor for processing the spoken instruction based on the determined speech recognition level. The noise level detector includes a DC rectifier to eliminate a DC component from the environment noise, and an A/D converter for converting the environment noise without the DC component in binary data which correspond to the noise level. |
