There are small differences between diphone set of the voices, but they are not used from espeak-ng

There are small differences for diphone sets, but these are not used
from eSpeak NG.

This is a Variant I created called male8, probably one of the smoothest sounding espeak male variants ever. It sounds very good with inflection at 100, which I don't know if you can only change in NVDA or other programs too.

These are some improvements to the german voices, both default and mbrola. It fixes some sounds of phonemes and also pronunciation of words. I also modified the mbrola phoneme and voice files to make them sound more natural. The stressLength setting is that it matches the way espeak deals with the lengths.
