Hi,

I want to implemment HMM of speech recognition using matlab . what can i do because i need to improve quality of speech recognition.

If you have Statistics Toolbox, take a look at HMM there.

MATLAB: How to replace only a single instance of a substring

Lines such as

 inp = replace(inp, inp(1,i),'n')

should be

 inp(1,i) = 'n';

This only affects a single location, and prevents positions from being changed twice. With your existing code, suppose your text started with 'a' and got replaced by 'n'. Suppose there was also an 'n' in the input. Then when you go to work on that 'n' on input and you go to replace the first 'n' with 'a', you would end up replacing the 'n' that you had generated from the 'a' . Your code should not be replacing inside anything it has already replaced.

MATLAB: Fsolve

preallocate beta

beta = zeros(nmax+1,1);
beta(1) = beta_of_1;
for ii = 1:nmax
 beta(ii+1) = fsolve(F,beta(ii));
end

EDIT more stuff:

You calculate:

'sqrt((Ko^2-(x)^2))*b': 4x
'sqrt((Ko^2*Ed-(x)^2))*a': 4x
the bessel functions multiple times a pop.

Turn your function handle into a function. Make each of these calculations once, then use them multiple times.
