/** 
 * Text To Speech synthesis library 
 * Copyright (c) 2008 Clive Webster.  All rights reserved.
 *
 * Nov. 29th 2009 - Modified to work with Arduino by Gabriel Petrut:
 * The Text To Speech library uses Timer1 to generate the PWM
 * output on digital pin 10. The output signal needs to be fed
 * to an RC filter then through an amplifier to the speaker.

 * Modified to allow use of different PWM pins by Stephen Crane.
