DEVICE CONTROL USING SPEECH

Device are controlled with speech using parallel port.

Description

The purpose of the speech is communication. The area of speech processing is just developing, and shows the tremendous potentialities for widespread use in the future.

In this project we have processed the speech signal with the help of the DIGITAL SIGNAL PROCESSING techniques. The speech signal is given as the input will be verified using speech recognition technique using matlab. We have used Mel Frequency Cepstral Coefficient (MFCC) along with Vector Quantization (VQLBG) and Euclidean Distance to identify different characters. Based on the results, data was send to Parallel Printer Port of the computer & using relay different devices will be controlled.

• Required Products: Signal Processing Toolbox
• MATLAB release: MATLAB 6.5 (R13)

HI

  THAT PROJECT IS REALLY VERY INTERESTING BUT WHEN I RUN THE CODE THAT KIND OF ERROR COMES

ILLEGEL FILE '11L' OR UNDEFINE FILE AT THE TIME WHEN THAT COMMAND EXECUTE

    filename = '11L.wav' % Calculate the codebook vector.

    cep = learn('11L.wav');
    codebook = vqlbg(cep, 8);
    result(1) = identify(filename, codebook);

    cep = learn('O.wav');
    codebook = vqlbg(cep, 8);
    result(2) = identify(filename, codebook);

    cep = learn('U.wav');
    codebook = vqlbg(cep, 8);
    result(3) = identify(filename, codebook);

    cep = learn('V.wav');
    codebook = vqlbg(cep, 8);
    result(4) = identify(filename, codebook);

AND PLEASE HELP WHAT IS CODEBOOK VECTOR.

i have also same problem as SHABAB MEHDI..
Can u plz provide with all related files..

CODE BOOK VECTOR.......????

[banty agarwal]

hey ankit i m doinga project on contrllig devices thru mobile and i m using matlab foe speech recognition .i wanted to use contious speech recognition method since we will be using words like "switch on the fan". do u have any knowlege how to use hmm model.
thanx

[Foram Kothari]

Thanks. This project was very useful in understanding the basic Speech recognition.

hi ankit you r doing your wirk very well. i am giving u 10/10 marks for this work . go dear go.........

how to save the data obtained in matlab in text file

[HD DODA]

this is very informative

[Beenish Fatima]

hi..u have used a lot of functions like learn, vqlbg, identify which are not matlab functions although this is a .m file..can you please help regarding this..thanks!

[Beenish Fatima]

sorry..i didnt see that these functions are user defined and written below..

[shrikant modh]

Hi
good work but there is a confusion with functions.
can u tell me how u calculated the euclidean distance.
I have similar project of speech recognition system using DSP.
Please i want ur help

[Gurudath Vashist]

Hey. Nice project. I am currently working on a project involving HMM's for speech recognition. i have converted the wave file into cepstral feature vectors.
my question is, wat are the states and symbols associated with the HMM in speech recognition. also, is there a way to make a HMM without knowing the transition and emission probabilities?

I request a speedy response from all.

thank you

[shreya]

i want speech recognition code using hidden markov model will u help me

I want to control a servo motor with my only voice pls help me.

[Lokesh Peddireddi]

hello, i have seen your project and really interesting. The source code provided by you was helpful for us. But the file with name codebook vector is missing can you send me file so that I can learn about it in detail.

hey v need to record all the wav files first. then save all wav files in the directory as that of test_project.m. M i right ankit mehta??
