#719 How to change default voice

I wonder, how to change default voice? I couldn't find anything about it anywhere on the internet.

I don't mean how to change it with -v, but really the default voice (which comes quite terrible). Since I use it with speech-dispatcher and that is called by another software, I cannot pass any arguments.

If anyone has some comparison, I wonder, can espeak-ng come quality-wise close to the Japanese nittech NTS voices on Festival?
