    Product Details
    Product Description:
    Voice Recognition Module is a compact and easy-control speaking recognition board.
    This product is a speaker-dependent voice recognition module. It supports up to 80 voice commands in all. Max 7 voice commands could work at the same time. Any sound could be trained as command. Users need to train the module first before let it recognizing any voice command.
    This board has 2 controlling ways: Serial Port (full function), General Input Pins (part of function). General Output Pins on the board could generate several kinds of waves while corresponding voice command was recognized.
    What are the updated features ?
    We already have Voice Recognition module V2 and it supports 15 commands in all and only 5 commands at the same time.
    On V2, voice commands are separated into 3 groups while you training it. And only one group (5 commands) could to be imported into Recognizer. It means only 5 voice commands are effective at the same time.
    On V3, voice commands are stored in one large group like a library. Any 7 voice commands in the library could be imported into recognizer. It means 7 commands are effective at the same time.
    Parameter
    1、Voltage: 4.5-5.5V
    2、Current: <40mA
    3、Digital Interface: 5V TTL level for UART interface and GPIO
    4、Analog Interface: 3.5mm mono-channel microphone connector
    and microphone pin interface
    5、Size: 31mm x 50mm
    6、Recognition accuracy: 99% (under ideal environment)
    Feature
    1、Support maximum 80 voice commands, with each voice 1500ms
    (one or two words speaking)
    2、Maximum 7 voice commands effective at same time
    3、Arduino library is supplied
    4、Easy Control: UART/GPIO
    5、User-control General Pin Output

    Application
    Example 1
    Here i will show you an example how to control RGB by voice.
    1. Recording
    We need to send serial command to this module. You may need a USB-TTL module to connect it with PC. Send command 0xaa11 to record. Please refer to the manual for more information.
    Please record the following voice instrctions in order :
    1、WHITE
    2、RED
    3、GREEN
    4、BLUE
    5、OFF
    Then send command 0xAA21 to import group 1.
    2. Hardware connection
    The module in above picture is V1. For V2, the connection is the same.
    3. Code
    int redPin = 11; // R petal on RGB LED module connected to digital pin 11
    int greenPin = 9; // G petal on RGB LED module connected to digital pin 9
    int bluePin = 10; // B petal on RGB LED module connected to digital pin 10
    byte com = 0; //reply from voice recognition
    void setup()
    {
    Serial.begin(9600);
    pinMode(ledPin, OUTPUT); // sets the ledPin to be an output
    pinMode(redPin, OUTPUT); // sets the redPin to be an output
    pinMode(greenPin, OUTPUT); // sets the greenPin to be an output
    pinMode(bluePin, OUTPUT); // sets the bluePin to be an output
    delay(2000);
    Serial.write(0xAA);
    Serial.write(0x37);
    delay(1000);
    Serial.write(0xAA);
    Serial.write(0x21);
    }
    void loop() // run over and over again
    {
    while(Serial.available())
    {
    com = Serial.read();
    switch(com)
    {
    case 0x11:
    color(255,255,255); // turn RGB LED on — white
    break;
    case 0x12:
    color(255, 0, 0); // turn the RGB LED red
    break;
    case 0x13:
    color(0,255, 0); // turn the RGB LED green
    break;
    case 0x14:
    color(0, 0, 255); // turn the RGB LED blue
    break;
    case 0x15:
    color(0,0,0); // turn the RGB LED off
    break;
    }
    }
    }
    void color (unsigned char red, unsigned char green, unsigned char blue) // the color generating function
    {
    analogWrite(redPin, red*102/255);
    analogWrite(bluePin, blue*173/255);
    analogWrite(greenPin, green*173/255);
    }
    Upload the code above to Arduino. Please disconnect TX and RX while uploading code because uploading would occupy serial interface.
    4. Result Show
    After uploading is done, connect RX and TX, and then press RESET button on Arduino.
    You can see the video on Youtube
    Example 2
    Here we will show you how to use the GPIO output to control other device.
    Step 1
    First you have to record the voice instruction. Send command 0xAA12 (group 2).
    Please record the following 5 voice instructions in given order:
    “One”
    “Two”
    “Three”
    “Four”
    “Five”
    Please note you have to speak clearly.
    Step 2
    Connect the device with LEDs in the following way :
    Step 3
    Import voice group 2 by command 0xAA22 or set pin GCH HIGH and pin GCL LOW
    Speak voice instruction.
