This is a view of the WMU Speech Physiology Laboratory.  The laboratory is
approximately 600 square feet.  It contains a wide range of instrumentation for
the study of speech motor behavior as well as a number of PC workstations for
data processing and analysis.

 

The centerpiece of the laboratory is a
12 channel Carstens AG200 Articulograph.
This instrument allows high fidelity movement
recording of lips, jaw and tongue during speech,
swallowing and other oral behaviors.  We have
used this technology to acquire a large database
of normally fluent adult speakers and adults persons
who stutter.   

 

The laboratory is also equipped with
a Kay digital videolaryngostroboscopic system.


 

The laboratory has a 16 channel data acquistion
system that allows for the synchronous recording
of a wide range of physiologic signals.  We have
a wide range of instrumentation for recording speech
and voice acoustics, chest wall movement (Respitrace),
muscle activation patterns (EMG), speech-related oral flow
and pressure, and laryngeal activity.
