This Voice Recognition Module, which can recognize as much as 15 voice instruction and be suitable for most cases involving voice control. It receives configuration commands or responds through a serial port interface. With this module, we can control cars or other electrical devices by voice. 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. If we need to implement instructions in other groups, we should import the group first. This module is speaker-independent. If your friend speaks the voice instruction instead of you, it may not identify the instruction.
