We compare two methods of acquiring
ultrasound tongue images. A new system capable of
recording directly from the cineloop image buffer at
a high frame rate and which is more accurately
synchronized with audio is compared with an
optimised method of recording images via the NTSC
video output of an ultrasound machine. As a focus
for this comparison we gathered representative
data on English /l from a single speaker, using a
headset restraint system. Both systems performed
well, but while the video system is at its limits, the
cineloop system is inherently more accurate and
offers greater opportunity for development.caslpub2012pu
