High-speed Cineloop Ultrasound vs. Video Ultrasound Tongue Imaging:\ud Comparison of Front and Back Lingual Gesture Location and Relative Timing.

By Alan A Wrench and James M Scobbie

Abstract

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