text-to-speech through DAC to audio amp/speaker
text-to-speech TTS
- This program was based on modifying the Arduino/Teensy TTS library https://github.com/manitou48/TTS
- The audio is generated with the ARM's DAC pin.
- TTS.h selects DAC pin based on MBED board. Only tested on K64F
- Teensy discussions https://forum.pjrc.com/threads/44587-TTS-(Text-to-Speech)-Library-Port
