ABSRACT: Phoneme inventories of the world’s languages as depicted by the UPSID database (Maddieson and Precoda 1990) are analyzed using multivariate statistical techniques of principal components analysis and k-means and hierarchical clustering. The first two meaningful principal components, representing dimensions that account for the most variance in sound systems but are not caused by differ...

This paper presents a new approach to phoneme recognition using nonsequential sub{phoneme units. These units are called acoustic events and are phonologically meaningful as well as recognizable from speech signals. Acoustic events form a phonologically incomplete representation as compared to distinctive features. This problem may partly be overcome by incorporating phonological constraints. Cu...

MIDI commands provide an abstract representation of audio in terms of note-on and note-off times, velocity, and controller data. The relationship of these commands to the actual audio signal is dependent on the actual synthesizer patch in use. Thus, it is hard to implement effects such as compression of the dynamic range or time correction based on MIDI commands alone. To improve on this, we ha...

The magnetic and metabolic activational patterns of the brain during the perception, generation and silent articulation of words overlap to some extent, yet also measure concrete activational patterns. In the present study, auditory evoked magnetic fields (MEG) and changes in regional cerebral blood flow (PET) were examined in healthy subjects during a verb generation task. The aim of the study...

[Purpose] The purpose of this study was three kinds of stretching methods and measured the change in the thickness of the piriform muscle in real time using ultrasound images and compared the medial rotation angle of the coxal articulation. [Subjects and Methods] Fourty-five subjects who attend B University in Cheonan, divided into three groups. The subjects in these three groups then underwent...

We outline a structured speech model, as a special and perhaps extreme form of probabilistic generative modeling. The model is equipped with long-contextual-span capabilities that are missing in the HMM approach. Compact (and physically meaningful) parameterization of the model is made possible by the continuity constraint in the hidden vocal tract resonance (VTR) domain. The target-directed VT...

At 14 months, children appear to struggle to apply their fairly well-developed speech perception abilities to learning similar sounding words (e.g., bih/dih; Stager & Werker, 1997). However, variability in nonphonetic aspects of the training stimuli seems to aid word learning at this age. Extant theories of early word learning cannot account for this benefit of variability. We offer a simple ex...
