Horn Police ...

Good afternoon everyone,

I wonder if it is possible to create a project where I can get through ROM or memory card , have my mp3 / wave and pressing buttons activate them.
And with microphone input .

Using such a keyboard

The project is for a motorcycle .

Something of this kind ....
