4×4 Matrix Keypad Module In Pakistan

This Voice Recognition Module, which can recognize as many as 15 voice instructions 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.
