Support for regional CJK accents #127
Description
some text-to speech examples from various websites (find free demos)
also even espeak some CJK vocels/accents sound very strange/strong
that maybe due to accent variations : e.g. Taishanese early wave e-migrating before mainstream (https://en.wikipedia.org/wiki/Cantonese)
ekho's cantonese setting, does reasonable quality can this be used to re-tune the vowels?
Note: tonal language's tone curves in espeak are rather inadequate, it looses a lot of nuance that affect how the words sound and also contributes to the accent
also should improve espeak's voice settings (MAX-MIN pitch)
should it do rather, central pitch(geomean) and relative-ratios between max&min
