Hi everybody;
I want to tell you what i did and what i need. I made a data base including
phonemes like '' -th,-sh, ai,-ea .." i recorded this phonemes in a wav
file. I read a text and recorded it in a wav file. I have a system that you can
process the speech with fft,dct and wavelet transform than you have two options
for matching or comparing two speech datas. This options are DTW and Cross
correlation. I want to find out selected phoneme how many times used in this
speech. But when i want to use dtw and cross correlation i have a problem
because it cant make efficient compare. So I want to determine the
speech\nonspeech parts of the speech. and try to compare this speech part to
phonemes so find out how many times this phoneme used in this speech. I find a
way which is short time average zero crossing rate but only a short expression I
couldt find its algorithm(pseudo code). Would someone propose me an
algorithm(pseudo code) or a source code(c,c++ or c#) which I can use. thanks in
advance.
best regards
c
