Voice recognition is something that knows exactly what you were saying. It differs from Sound Control, which means controlling the light on and off by making a sound. We've been thinking about a low-cost module which helps to control other devices by voice. Finally we designed this Voice Recognition Module, which can recognize as much as 15 voice instruction and be suitable for most cases involving voice control.

It 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.
