Dear Sir/madam,
Im currently working on Isolated Word Speech Recognition Systems and i hardly need code for better understanding and the flow of approach!!! So if u grant me the code then it will be a great help for me.
Thanking you,
Best Regards,
Satheesh Kumar

Voice recognition technology is integrated into voice-activated routing systems in customer call centers, voice dialing on mobile phones and many other everyday applications. A robust voice recognition system combines the accuracy of identification with the ability to filter noise and adapt to other acoustic conditions, such as the speaker's voice frequency and accent. The design of a robust speech recognition algorithm is a complex task requiring detailed knowledge of signal processing and statistical modeling.
The speech detection algorithm is developed by processing the pre-recorded frame frame by frame within a single loop. For example, this MATLAB code continuously reads 160 sample frames from the data in 'speech'.
Quote:% Define system parameters
seglength = 160; % Length of frames
overlap = seglength/2; % # of samples to overlap
stepsize = seglength - overlap; % Frame step size
nframes = length(speech)/stepsize-1;
% Initialize Variables
samp1 = 1; samp2 = seglength; %Initialize frame start and end
for i = 1:nframes
% Get current frame for analysis
frame = speech(samp1
amp2);
% Do some analysis
...
<DO _ SOMETHING>
...
% Step up to next frame of speech
samp1 = samp1 + stepsize;
samp2 = samp2 + stepsize;
end
