% This function allows the user to stipulate which Singing voice LLD's they
% wish to forward to a k-means classifier and produces a file of
% performance characteristics. Input arguments stipulate the LLD's and
% there is a choice of:-
%
% ---- PRAAT JITTER MEASUREMENTS ----
%     '_jitter_ddp'
%     '_jitter_local'
%     '_jitter_ppq5'
%     '_jitter_rap'
% ---- PRAAT SHIMMER MEASUREMENTS ----
%     '_shimmer_local'
%     '_shimmer_dda'
%     '_shimmer_apq3'
%     '_shimmer_apq5'
%     '_shimmer_apq11'
% ---- PRAAT FORMANT MEASUREMENTS ----
%     '_Formant_Burg'
%     '_Formant_all'
%     '_Formant_robust'
%
% A text file entitled kmeans_Singing_LLD1name_LLD2name_ ... LLDNname.txt
% is produced that contains the results of the k-mean classification for
% the LLD's specified and named in the result document title.
