Quiotepec dialect. Highland Chinantec is spoken
in Ixtlan district, Oaxaca, Mexico. Robbins (1968)
analyzes it as having three level tones and stress.
Syllables with short vowels have only one tone. Syllables
with long vowels can have rising and falling combinations
of these levels. The only syllable-final consonant is /?/.
Oral and nasalized vowels occur after voiceless
obstruents, but nasal consonants and prenasalized stops
are in complementary distribution. This is interpreted as
'oralization' of nasals before oral vowels (i.e.
/ma/=[mba] etc.) Clusters of /?/ + nasal or /w, j/ occur
but all other clusters posited by Robbins have been
interpreted as single segments. Note especially his 'hg'
is interpreted as the voiceless velar nasal. Phonetically
he transcribes it as a prenasalized stop with a voiceless
nasal onset and although he says that 'h' can "precede any
nasal" there are no examples of 'h' before 'eng' anywhere
in his grammar.
