Comments:

In open syllables there is a contrast between
long and short vowels. Ebert notes ten words with
nasalized vowels. We have interpreted these as having a
palatal nasal -- medially this varies with nasalized /j/,
finally it is lost leaving a nasalized vowel. Kera has 3
level tones and glides composed of their combination.
There is a strong interrelationship between tone level and
obstruent consonant voicing (laryngealized stops go with
voiceless ones).
