manitou 0:bcd16e4a0207 5 * Nov. 29th 2009 - Modified to work with Arduino by Gabriel Petrut:
manitou 0:bcd16e4a0207 6 * The Text To Speech library uses Timer1 to generate the PWM
manitou 0:bcd16e4a0207 7 * output on digital pin 10. The output signal needs to be fed
manitou 0:bcd16e4a0207 8 * to an RC filter then through an amplifier to the speaker.

manitou 0:bcd16e4a0207 11 * Modified to allow use of different PWM pins by Stephen Crane.
