		+	'Description':
		+
		+
		+	We all know that there is some kind of moudle that can control the light on and off by voice. If you make a sound, the light will turn on. Then after a while the light turns off. This is not voice recognition. We may call it Sound Control. Voice recognition is something that knows exactly what you were saying. We've been thinking about a module which helps to control other devices by voice and it will not cost too much. Finally we designed this module. Well, what can this module do? It can recognize as many as 15 voice instructions, which is suitable for most cases involving voice control.
		+
		+
		+
		+	Parameters
		+	*Voltage:4.5-5.5V
		+	*Current:<40mA
		+	*Digital Interface: 5V TTL level UART interface
		+	*Analog Interface: 3.5mm mono-channel microphone connector + microphone pin interface
		+	*Size: 30mm x 47.5mm
		+
		+
		+	This module can store 15 pieces of voice instruction. Those 15 pieces are divided into 3 groups, with 5 in one group. First we should record the voice instructions group by group. After that, we should import one group by serial command before it could recognize the 5 voice instructions within that group. If we need to implement instructions in other groups, we should import the group first. This module is speaker-dependent. If your friend speaks the voice instruction instead of you, it may not identify the instruction.
