Preglottalized consonants, which can only appear root-initially, are analyzed as /ʔC/ sequences here, but it seems better for comparative purposes to assign each one phonemic value. No inventory is given, however, so this is a guess; it's unclear if /ˀs ˀh/ exist.

- t > ts / _{i j}
- ts > tɕ / _{i j}
- ˀts > ˀtɕ / _{i j}
- dz > dʑ / _{i j}
- n > ɴ / _{-
- ɾ > 0 / _{i j}
