eSpeak is a compact open source software speech synthesizer for English and other languages. It is a port of eSpeak over to the Nintendo DS.
The homebrew works without modifications on the DS, but it only can generate .wav files.
See ./arm9/espeak/espeak_global.h for samplerate, sound format (8/16 bit) and the data-path setting.
- Get rid of warnings.
- Add an option to decide between 8bit or 16bit.
- Add an option to decide between 22050 or 11025 Hz (or even lower).
- Removed the usual main() function with the getopt stuff and instead did a ES_InitCFG function.
- Stdout is used during the writing process to get the stuff into the buffer (added a io handler).
