A quick tutorial on how to glue
sensors on the tongue
EMA AG series (Electromagnetic
Articulograph, Carstens GmbH, Germany) and Wave system (NDI
Inc., Canada) are two available electromagnetic
devices that have been
increasingly used for speech movement studies. However,
sensor falling off during data collection may be one of the
biggest obstacles for obtaining reliable data. This quick
video tutorial shows how we attach tongue sensors on a
subject's tongue. This approach is used with both devices.
Step 1. Dry the tongue surface using Dry-Angle
Step 2. Put one drop of glue on the sensor side that
will be flipped and then touch the tongue surface
Step 3. Using a tongue depressor to hold the sensor
for a few seconds (10 or more); flip the tongue
depressor to avoid stickiness to the tongue.
Step 4. [Optional] Put one more drop of glue on the
root of the attached tongue sensor, if needed. Then hold it
again for a few seconds using a tongue depressor.
Other relevant procedure and setup (e.g., sensor
locations) are described in my papers
using EMA or Wave. If you want to give credit, please cite
any of my recent papers.
