Phonological discoveries in Watakassi

I've discovered some interesting allophonic variations, like:

/w:/ = [B:]
/j:/ = [j\:]

Also, some interesting phenomena with the tonal-patterns:

/p:/ /t:/ /k:/ when preceded by a low vowel and followed by a high vowel
become slightly ejective, the reason being the tone-contours:
               _--------
             _-
           _-
         _-
       _-
______-
u       p a       |
u       p      a       |
(| indicates the end of the word)

Notice that the tone only rises slightly on the consonant in upa', while
it rises more in the uppa', the laranyx must move more during the stop,
causing pressure to build up which is released as a slightly ejective
quality.

With voiced stops, there's no rise on the consonant, in fact, there's a
slight drop on the voiced stop, creating something like:
                      __
                     _
                    _
                   _
                  _
     _           _
____- ----___   _
             ---
u    b         a

In a later stage, /b:/ evolved into /b`/
(ubba' isn't a real word, I just invented it for this demonstration.
