ITEM NAME:Voice Recognition Module With Microphone Dupont Jumper Wire Speech Recognit A7M4 Voice Recognition Module With Microphone Dupont Jumper Wire Speech Recognit A7M4 Introduction: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. which can recognize as much as 15 voice instruction and be suitable for most cases involving voice control.This Voice Recognition Module could recognize your voice. It receives configuration commands or responds through 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. Please note that speaker independence requires strictly good MIC. The MIC we supply may be not good enough for it to be speaker-independent. Voltage:4.5-5.5V Current:Less than 40mA Digital Interface: 5V TTL level UART interface,Recognition accuracy: 99% (under Perfect environment) Analog Interface: 3.5mm mono-channel microphone connector + microphone pin interface Size: 30mm x 47.5mm Colour: Black Material: PCB Package Contents: 1 x Voice Recognition Module 1 x Microphone 5 x 30cm 1pin female to female jumper wire
