/w/ metathesizes with /t/, and the resulting /wà/ is realized as /ò/.
Unstressed /ë/ of the root is elided.
An unrelated /ë/ is inserted as a transition sound between /m/ and /w/.
Both /wa/ sequences are realized as /o/.
An unrelated /w/ is inserted as a transition sound between /ë/ and the first /o/.
