%% Loading data from folder clear,clc % clear space

fs = 44100; % frequency

phonems = dir('*.wav');  % checks current directory for .wav files numfiles = length(phonems); % finds number of wav files

% converts each wav file into its coresponding variable with name for i = 1:numfiles

   titles = phonems(i,1).name;
   [~,sound_name,ext] = fileparts(titles);
   eval([sound_name '= audioread(phonems(i,1).name);']);   

end

%input section input_phonems = ['Input the word you want in the form\n of the phonems shown'...

   'as wav files with\n 1 space inbetween each phonem\n'];

% text = input(input_phonems,'s');

text = 'ha eh ll O wu er ll du th ii ss wu aa eh zz du nn bu I ss aa mm gu ar vv ii ss'; % this is here for the example

parts = strsplit(text); % splits text into readable parts

speech = []; % creates speech bracket space

% adds on to previous speech in order to make the speech for j = 1:length(parts)

   eval(['section = ',char(parts(j)),';']); % evaluates each section and returns the double struct
   speech = [speech; section];   

end

sound(speech,fs) % plays text plot(speech) title('Speech') xlabel('time (s)') ylabel('Amplitude') % example: ha eh ll O wu er ll du - hello world
