چکیده

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.

The role of anterior lingual gesture delay in coda /r/ lenition: An ultrasound tongue imaging study

We investigate the contribution that lingual gesture delay makes to lenition of postvocalic /r/. This study uses a socially-stratified, audio-ultrasound corpus of Scottish English containing recordings from two sociolects; one with postvocalic /r/ weakening and the other with strengthening. We quantify auditory strength of rhoticity and the timing of the anterior lingual gesture relative to the...

Rarefaction gestures and coarticulation in mangetti dune !xung clicks

We provide high-speed ultrasound data on the four Mangetti Dune Xung clicks. The posterior constriction is uvular for all four clicks—front uvular for [ ] and [ ] and back uvular for [ ] and [ ]. [ ] and [ ] both involve tongue center lowering and tongue root retraction as part of the rarefaction gestures. The rarefaction gestures in [ ] and [ ] involve tongue center lowering. Lingual cavity vo...

An ultrasound analysis of low back vowel fronting in the Northern Cities Vowel Shift

While the acoustic characteristics of the Northern Cities Vowel Shift (NCVS) are well documented, research on the articulatory components of this shift is comparatively limited. This study combines acoustic, video, and ultrasound analysis to examine the productions of seven Metro Detroit speakers and determine the relative contributions of lip configuration and tongue position to the production...

Neural Network Performance Analysis for Real Time Hand Gesture Tracking Based on Hu Moment and Hybrid Features

This paper presents a comparison study between the multilayer perceptron (MLP) and radial basis function (RBF) neural networks with supervised learning and back propagation algorithm to track hand gestures. Both networks have two output classes which are hand and face. Skin is detected by a regional based algorithm in the image, and then networks are applied on video sequences frame by frame in...
