How to play .wav

Is there a way to load and play .wav files? This is what I have:

s = 'diglett.wav';
Fs = 8000;
audiowrite(s,y,Fs);
clear y Fs
[y, Fs] = audioread('diglett.wav');
soundsc(y,Fs);

But I know this is wrong. I really need it to xcorr with recorded audio from mic and I don't know if this is even the right way to do it.

Is there a way to load and play .wav files? I got this code but the .wav files cannot play the sound.

myFileName = 'abang.wav';
myDirectory = 'C:\R2013a\bin\Recordings\abang.wav';
filepath = fullfile(myFileName, myDirectory);
if exist(filepath,'file') ==2;
   [y,Fs] = audioread('abang.wav', string);
    load abang;
   sound(y,Fs);
load abang.wav
playerObj = audioplayer(y,Fs);
start = playerObj.SampleRate *4;
play(playerObj,start);
end

myDirectory = 'C:\R2013a\bin\Recordings';

You cannot load a .wav though.

And what is string in your code? It would have to be either 'double' or 'native' or a vector of two numeric values for that code to work.

Okay, my bad.Actually, I am writing a Malay language text to speech program.Its very simple; it reads the string from the .txt file,scan it and then matches it in the database, and plays the wave file that match of the string . The database holds the .wav files of word, e.g. the word "saya" has a corresponding file saya.wav in the database. I know this code is wrong because it cannot play the wav file. Can you help me. So far my code is:

%scan text from file
fid = fopen('saya_1.txt');
C = textscan(fid,'%s %s %f32 %d8 %u %f %f %s %f');
fclose(fid);

%connection to SQLite database
javaaddpath('C:\Users\user\AppData\Roaming\MathWorks\MATLAB\R2013a\sqlite-jdbc-3.8.11.2.jar'); 
dbpath =('C:\Users\user\Desktop\db\tts.db');
datasource = 'tts';
user = '';
password = '';
driver = 'org.sqlite.JDBC';
protocol = 'jdbc';
subprotocol = 'sqlite';
resource = dbpath;
url = strjoin({protocol, subprotocol, resource}, ':');
conn = database(dbpath, user, password, driver, url);


%match string to database   

query = 'SELECT *FROM MALAY';
cursor = exec(conn, query);
cursor = fetch(cursor);
result = cursor.Data;

%match string from scan to database
str = {'C'};
expression = '\w+';
matchStr = regexp(str, expression,'match');


%match the string with voice recording

wavdirectory = 'C:\R2013a\bin\Recordings';
[~, number_of_words] = size(matchStr); %stores number of words in user    
											   % input string                
for m = 1:number_of_words
    filename = [wavdirectory matchStr{m} '.wav'];
   if(exist(filename, 'file') ~= 0)
     [y, fs] = audioread(filename); 
     sound(y, fs);
   else
       fprintf('Word %s does not exist', wordsstring{m});
  end
end

[Walter Roberson]

    filename = fullfile(wavdirectory, [matchStr{m} '.wav']);
