Because of where the robot understand human speech?

(Photo: aniguild.com) In order for the robot to hear and understand human language, there must be an electronic card inside the robot with microphone for sound recording and audio recording chip. After the electronic card is a CPU card that runs with a pre-programmed software with sample words (such as ' go ', ' backward ', ' left ', ' right ' .) and audio spectrum analysis software .

When the robot is in operation, the operator will issue a voice command. The software in the receiving robot will analyze the audio spectrum with the waveform and the amplitude ratio of the mono, comparing the voice file to the programmed file.

After the spectrum has been solved, the logic circuit will issue a command to control the motor or electronic device to execute the command that the logic problems have been prepared. The more intelligent a robot is, the more commands it can execute, in order to do this, the robot maker must program many commands and solve the problem of analyzing the code according to the sound spectrum.
