Speech Recognition With BitVoicer and Arduino

Intro: Speech Recognition With BitVoicer and Arduino

The main goal of this project was to test the speech recognition performance of BitVoicer (http://www.bitsophia.com/BitVoicer.aspx). For this purpose, I designed a simple led control sketch which I integrated with BitVoicer. Of course you can do anything you want once you have received the commands from Bitvoicer, but to keep things simple, I thought a led test would do just fine.

Here is the YouTube video with the results:

This is the Arduino sketch that controls the leds and retrieves data sent from BitVoicer:

//Includes the BitVoicer library to the sketch
#include <BitVoicer.h>

//Sets up the pins and default variables
int pinR = 3;
int pinY = 5;
int pinG = 6;
int blinkDelay = 250;
int sequenceDir = 0;
int lightLevel = 0;

//Creates a new instance of the BitVoicerSerial class
//Sets up serial port to 0
BitVoicerSerial bitVoicer = BitVoicerSerial(0);

void setup()
{
  //Starts serial communication and sets up the pinModes
  Serial.begin(9600);
  pinMode(pinR, OUTPUT);
  pinMode(pinY, OUTPUT);
  pinMode(pinG, OUTPUT);
}

void loop()
{
  //Retrieves data from serial buffer 
  bitVoicer.getData();

  //Quits the loop if no string data was returned from getData
  if (bitVoicer.strData == "")
  {
    return;
  }

  //Each of the next 'if' statements performs a different
  //task based on the data received from BitVoicer
  if (bitVoicer.strData == "wake")

This sketch uses the BitVoicer Arduino Library that can be downloaded from their website: www.bitsophia.com.

The BitVoicer Voice Schema that recognizes the speech shown in the video is available at: http://www.justbuss.xpg.com.br/BitVoicerTest.zip (you need to have BitVoicer installed in order to open it).

I hope you guys have fun with it!

I need total information about how to use this software and how to connect it with arduino.

[VintD]

and resistor is 330 ohm?

[suryak53]

dude, i have a question. bitvoicer runs in the pc, but i want to run the project separately without connecting aurdino to the pc? now will the bitvoicer library be loaded in aurdino? ( i ll give the power to the aurdino via adapter)

[sentiner]

Should i connect the arduino to the computer???

[ValentinaM22]

Instead of using a voice, can I just use a harmony (a few keys) from my Clarinet?

[paulrobert27]

I have a question my friend. Will i have to open the sketch and the Bitvoicer when do i run the project?

[leandro4b]

You do not have to open the sketch (Arduino IDE), but BitVoicer must be open and running. If you use BitVoicer Server, you do not have to open anything.

[paulrobert27]

Thanks very much leandro4b. I asked that because I haven't made the project yet. =).

[paulrobert27]

Thanks very much leandro4b. I asked that because I haven't made the project yet. =).

[ARYANB12]

do bitvoicer only works when it activated???

[leandro4b]

To enable communication with your Arduino, yes.

[PandulaM]

I have problem in this line

BitVoicerSerial bitVoicer = BitVoicerSerial(0);

and I try to solve it. but failed. Please help me

[leandro4b]

The code on this Instructable no longer works with the new BitVoicer library. Take a look at the example on this other Instructable and make the appropriate adjustments to the code.

[PandulaM]

thank you very much.

[adeelsaqib]

I have a problem.. when i upload this program to arduino... i got an error of

#include <BitVoicer.h>

can you help me plzzzz it's urgently...

[leandro4b]

What is the exact error message? Have you placed all the library files in the right folder? More information here: http://www.arduino.cc/en/Guide/Libraries

[adeelsaqib]

sir plzzz help me

[chiragc1]

shows error on compiling

error:'BitVoicerSerial' does not name a type????..pls help

[leandro4b]

Chiragc, this post is too old and the last BitVoicer version no longer has the BitVoicer.h library. Take a look at this post: https://www.instructables.com/id/Speech-Recognition-with-Arduino/. It is newer and uses the current version of the BitVoicer library.

[MAE38415]

I Do I need to connect arduıno to computer for this project? please answer quick . It's important to me.
