This study examines the effects of F0 and position on phonation in
Santa Ana del Valle Zapotec, a language that contrasts modal, breathy
and creaky voice on vowels. The first part of this experiment determined
that F0, and not position-in-utterance, influenced phonation. In the
second experiment, the effects of F0 on phonation were examined in
more detail. Speakers were asked to produce words from each phonation
in four prosodic positions: in isolation (high F0), focused sentence-initially
(high F0), sentence-medially (mid F0) and
sentence-finally (lower F0).
In medial position, a contrast between breathy, modal and creaky voice
was found. In sentence-final position, when the tokens had a lower
F0, the contrast between modal, breathy and creaky voice was preserved,
but with modal and breathy words both breathier. In both isolation
and sentence-initial position, when tokens had higher F0, the contrast
between phonations was minimized.
