Introduction: 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.

and resistor is 330 ohm?

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)

Should i connect the arduino to the computer???

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

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

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.

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

do bitvoicer only works when it activated???

1 reply

To enable communication with your Arduino, yes.

I have problem in this line

BitVoicerSerial bitVoicer = BitVoicerSerial(0);

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

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.

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...

sir plzzz help me

shows error on compiling

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

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.

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