Hi I am wondering if anyone can help me with this problem. I am trying
to get the min dist between two vowels in two utterances and return the
values of the start of the vowel and the end of the vowel. I have
started the following code but need to know how to expand it ??!!
% Finds the point of best matching between a segment of file_a
% specified by a_start and a_stop (seconds) and a similar segment from
% file_b. Start and stop times of the segment b are returned
% The minim distance min_dist is also returned which is a measure of
% similarity of the two waveforms
[ya,fsa]=wavread(file_a); % Read the sound a
[yb,fsb]=wavread(file_b); % Read the sound b
n_lpc=round(fs/1000)+3; % Number of prediction coefficients
% Compute LPC coefficients
a_lpc=lpc(a_f',n_lpc); % Signal should be in columns -> transpose
b_lpc=lpc(b_f',n_lpc); % Signal should be in columns -> transpose
nf_a=size(a_f,1); % Number of frames for signal a
nf_b=size(b_f,1); % Number of frames for signal b
final_dist=; % LPC distance (frame level)
time_stamps=; % Time for each distance
I need to extract the times now!!
Can anyone help!!!
