The problem includes writing C++ programs for three stages:
 Modeling : Modeling speech signals
 Training : Creating a database of models for different speakers
 Testing : Identifying a speaker

It will have four different modules/functions :
1.
2.
ReadWave
Input : Input to this function is the .wav files obtained from different speakers .
Output : Output of this function is an array containing the data from the .wav file.
MakeFrame
Input : (i) Array obtained from the function ReadWave.
(ii) Duration of a frame.
(iii) Shift between two consecutive frames.
Output : Pointer to arrays containing the frames.

3. CalucalateMFCC
Input : Pointer to an array containing a frame.
Output : An array containing the MFCC’s (feature vector.)
4. CreateModel:
Input : The feature vectors
Output : The model . Eg Mean and Co-variance of feature vectors.
