Spatiotemporal Visualization of the Tongue Surface using Ultrasound and Kriging (SURFACES)

Vijay Parthasarathy, Maureen Stone, Jerry L. Prince
2005 Clinical Linguistics & Phonetics  
One method to analyse this motion is to acquire two-dimensional ultrasound images and extract the tongue surface contours from them.  ...  Quantitative and statistical analysis of these extracted contours is made difficult because of the absence of physical fleshpoint markers on them.  ...  Acknowledgments This research was supported in part by a grant (R01 01758) from National Institutes of Health of United States of America.  ...

Subjective relevance of objective measures for spatial impression

Lily M. Wang, Anders C. Gade
2000 Journal of the Acoustical Society of America  
This study sought to determine temporal correlates of articulator fleshpoint movements in orally read speech recorded from 20 normal adult speakers of American English.  ...  Discrete Hidden Markov phoneme Models ͑DHMMs͒ trained using data recorded from normally articulating children were then used to classify the same utterances and results of the automatic classification  ...  To improve the accuracy of this method the correlation function is fit to a quadratic function to find its maximum. Experimental data from a variety of at-sea tests is used in this analysis.  ...

Calculation of the A term of magnetic circular dichroism based on time dependent-density functional theory I. Formulation and implementation

2004 Journal of Chemical Physics  
Attempts to determine optimum reverberation times for normal hearing listeners, which are based on a balance between avoiding excessive reverberation and maintaining adequate signalto-noise ratios, lead  ...  One factor that likely contributes to the problem of understanding a talker in a mixture of sounds in reverberant spaces is that it is difficult to separate the target talker from the competing sounds.  ...  Jaw movement was decoupled from the movement of the other fleshpoints following Westbury ͑1994͒.  ...

Gemination in Italian: the GEMMA project

Maria‐Gabriella Di Benedetto
2000 Journal of the Acoustical Society of America  
Speakers' articulatory phonetic working spaces were defined as areas enclosed by tongue fleshpoint locations.  ...  The Leq of a discrete source in a noisy background can be determined with known high resolution from easily obtained field measurements. The procedure does not depend on frequency analysis.  ...  The sand moisture content was continuously measured from the weight of a mechanically balanced fixture holding ultrasonic transducers and the wet sand sample.  ...

On determination of microphone response and other parameters by a hybrid experimental and numerical method

Salvador Barrera‐Figueroa, Finn Jacobsen, Knud Rasmussen
2008 Journal of the Acoustical Society of America  
For the first one, the energies of the plates are expressed at the continuous level. The Hamiltonian of the system is then derived and discretized using the eigenmodes.  ...  Two percentile levels ͑L10 and L99͒ are used to separate the masking from the activity sound. The system acts to continually keep the difference between them constant.  ...  In the framework of the automation of the ultrasonic signal analysis project, we have followed the exploration of the wavelet theory, from the continuous transforms to the discrete ones, and the experiments  ...

Articulatory correlates of the voicing contrast in alveolar obstruent production in German

Susanne Fuchs
2019
The different positions are chosen in order to study the following hypotheses: 1. The presence/absence of glottal opening is not a consistent correlate of the voicing contrast in German. 2.  ...  The first experiment investigates glottal abduction in co-ordination with tongue-palate contact patterns by means of simultaneous recordings of transillumination, fiberoptic films and Electropalatography  ...  They varied F1 cutback in continuous steps from -150ms to 150ms.  ...
