Hi sreejithalokkan...

Makes much more sense now... ;o)

I will assume that you will need a a dedicated shell Audio I/O app for platform independence.
So I will suggest SOX...

I have to assume also that this is some _homework_ style project, but not necessarily so.

OK.

Think of your problem...

Keep it simple...

I am not going to give you the code directly as you learn nothing about what is going on...

Code:

1) Generate a function, let us call it "say_it()"
2) inside the function call SOX somehow to play your *.wav file. Something like this:-

say_it()
{
        /full/absolute/path/to/sox <your player options> somefile.wav
}

3) Use if - then - fi to call it something like this:-

number="one"
if [ "$number" == "one" ]
then
        # Your new function...
        say_it
fi

All "case"s can be catered for this way and this is its simplest and easiest to understand form, albeit slow...

Next try and make the function universal by making "somefile.wav" a variable...
