(1) It is possible to gather important information about the
temporal organization of gestures by simply looking at the
acoustic waveform of an utterance. While it is not possible to
observe the continuous movement of the oral constrictors, velum,
glottis and larynx, it is possible to identify the point in time
at which the changes in one of these constrictors is substantial
enough to cause the acoustic output to shift to a different
state. For example: (2) The nine utterances below are all
produced with a single labial constriction, in combination with
possible gestures of the velum and glottis. The overall goal of
the exercise is to infer as much as you can about the
organization of those gestures from the acoustic waveform. (3)
Your first task is to match the transcriptions of the nine
utterances above with their waveforms found in the diagams you
view (see below). To help you with this, a collection of Praat
files (A.collection) containing recordings of these nine
utterances (labeled simply A1-A9) can be
