i have an audio file in .wav format whose mfcc i want. pls help
actually i am working on speech recognition ,I got stuck in between its coding about mfcc feature extraction and vector quantization so I need help related to this coding either give me an idea or give me the full code I am expecting fruitfull reply thank you
hi .. i need a project to know if the speaker male or female using kmeans and mfcc i tried to make it but i don't know how because i must use train and test data thanks :)
hi all i need matlab code for features exctraction using mfcc to use these featurs in dialect recognition

how make speech emotion recogniton work with mfcc as features and Anfis as classifier in matlab? help me!!! thank you
Mel-frequency cepstral coefficients (mfcc) am i right this is what code is rquired for?? Can you explain little more what exactly your problem is?? If you know this technique what is the real issue matlab??? and also let me know what exctly you want to do?? I find it fairly simple to tmplement any mathemtical thing in matlab
Hi all. I want to implement a Text independent speaker recognition in matlab. I am using mfcc for feature extraction. I already create a voice print of the speaker. How to match those voice prints. Can anyone help me please ? Thanks in advance.
I have recorded 10 voice samples of words 'Left' and 'Right'. These records will be used to train the neural network . Now, For feature extraction I have got mfcc of the samples and now, i dont know how to use them to train the network or even create the network. And there is problem in determining target vector too. I need help in matlab code for
Hi, Please i need help with this matlab code. i am using this melcept function for different samples of me saying the word "one" here is my code =wavread('one.wav'); %Read In Sample a=0.95; aaaa1=filter(,1,aaaaa1); aaa1= melcepst(aaaa1,fs); i get an output for the different samples of me saying one as 54

Hello. You are in the right place. I have the code for speaker recognition using mfcc. But I used neural networks for pattern recognition. I believe neural networks are better than Vector Quantization. If you need that code send private message to me.
Hi guys I'm currently doing on project regarding speech recognition (on bird songs). I would like to ask what classification can easily done in matlab such as DTW, GMM, HMM, ANN, and so on? (perfer DTW) So far I've gotten the code for framing, windowing, and mfcc of input signal from: Besides that,
sir, i need to perform my major project on above mentioned topic so please give me appropriate code and links which can help me in performing this project. i will use microphone and matlab version of 2008.
plz send me the matlab code for concanating two feature extracting technique lpc and mfcc and plz send me code for that on my mail id
hello, i am working in project for classifing a human voice with SVM and it is based on the mfcc coefficient. i have the program in matlab to calculate mfcc, it give 12 vector of mfcc. and i have the tool box for svm (libsvm),and i don't know how i put the mfcc vectors in the SVM toolbox, i need your (...)
Hi, please see the following link of matlab codes: specially, function of "melcepst.m" implements a mel-cepstrum front end (mfcc) as a feature extractor for speech decoder. F in your equ. is frequency. It represents range of frequency between 0 to Fs by steps of Fs/N, where N is the l

Does mfcc mathod of feaure extraction work better for speaker independent speech recognition system? or we must use hmm?
Hi Sir, I have developed also two approaches for speech recognition for isolated words: The first one uses some spectral features (specgram related) with DTW (dynamic time warping) The second approach uses DTW (dynamic time warping) but with mfcc based features
Hello ashiya. I have done speech recognition using mfcc and neural networks (you can use hmmm if you want. All that you need to do is to select HMMM in the neural network dialog box in matlab). I have uploaded the code before itself. Here's the link Please do leave some comments and rate my blog. Bye.
Hello i also want to recover the speech from its mfcc coefficients in matlab.... can anyone help..... plzzzz
Here is some good examples: PLP and RASTA (and mfcc, and inversion) in matlab using melfcc.m and invmelfcc.m matlab Resources mfcc.m - matalb auditory processing toolbox, a lo - Source Codes R
I am doing voice recognition (or speaker recognition ) using matlab. I tried finding out the mfcc and then modelling GMM for every class with 12 components each. Now I have the input data and I want to find out the class that the data belongs to. How should I do that? Will this method give me some accurate results? If there is any other b
Is there a natural way to define distance between two rectangular matrices of different dimension? The matrix contains the mfcc of two speech signals. I need to compare them.I am coding in matlab. Please help me in this regard. Thank you!
Hi, I want to learn how can i use the mfcc with voice signal(.wav), Is anybody can write small code for it? Assume that I want to take mel frequency cepstral coefficients of example.wav. First of all, s = wavread('directory of example'); After that, what should i write to get mel coefficients ? Thanks a lot =) by the way, I use
Are the values in the matrix b=specgram(...) in matlab the STFT of the overlapping blocks of sample points? Because my doubt is , whether I can use the values in the matrix b to extract the mfcc coefficients?
i want to do the pre processing on a speech signal, the steps are framing, silence removal, pre-emphasis, windowing and mfcc. i have done it in matlab, but how to do those multiplications divisions squares in verilog??? PLZ reply soon....its urgent
You can use mfcc(Mel frequency cepstrum coefficients) for feature extraction.
Hi all, I have a question about HMM. I am doing a bird sound recognition project. For the database, I have extracted the mfcc features for each bird. Now I have to estimate the HMM parameters. How can I do it? \lambda =(\pi ,A,B)
Hi all, I have to do feature extraction by using mfcc for my wav. data. But I am stuck at the beginning:cry: My questions would be silly and I apologize at the beginning for that. So firstly I want to do frame blocking and then for each frame i will apply hamming window. I dont know about the points.... When I use matlab command, = wa
Hello guys, How to apply the mfcc(mel-frequency cepstral coefficient) coefficient into neural network using matlab? Please help me on this matter... This article may help you
What do you want exactly? What parameters are you using for recodnition, LPC, LPCC, mfcc...etc
Mel-filter Cepstral coefficients for sure. LPC parameters are not as robust as mfcc.
Hi i'm engineering student this is my first topic here ...I'm working on speech recognition system on matlab I need to kow what best solution to calculate speech featurs I read about mfcc & mel freq & cepstrum ... can any one help me ...

Hi all, am new to matlab, and I'm required to submit a voice recognition program in matlab using mfcc and vector quantisation. the objective is to create a database of different speakers uttering the same word and then subsequently, taking a new utterance of the same word by any speaker and matching it with the database and returning the (...)
I want to do Voice Recognition using matlab.Could anyone plz guide me from where i can start.Which matlab software i have to use Hi I think you can find all things for voice recognition in matlab. That you need is to understand the structure of voice recognition, for exemple : what is the acoustic vector ? (mfcc. PLP, LPC,...
Dear friends, For isolated word recognition I am creating mfccs from the filtered and endpoints detected voice. After created mfccs I look the distances between created mfccs of all words. Then the minimum distance is the recognized word. Is there anything wrong or missing by this system? Should I do anything after creating (...)
After mfcc you can go for vector quantization (Compute the euclidean distance) fix threshold based on the max. euclidean distance and detect the word.
Hello, I am trying to implement speech recognition using vector quantization in simulink. I have extracted the mfcc feature vectors with matlab code. Now i want to import this code to simulink. I tried to use the embedded matlab function block but its giving too many block errors for many functions in my program. Is there any other block (...)
