Make your Arduino talk! (Speech Synthesiser or Text-To-Speech library)

The other day I was asked by Joe to help him with a project (more about it later), which needs to produce sound, or in a simplest way, speak. I list here the simplest possible ways to do it.

 1. Cantarino

2. Text-To-Speech library
    Source :

    Some RC filter circuit and Amp need to be constructed at the output to produce the sound.
