This paper investigates the problem of verifying the pronunciations of phonemes from continuous utterances collected from impaired children speakers engaged in a speech therapy session. A new pronunciation verification (PV) approach based on the subspace Gaussian mixture model (SGMM) is presented. A single SGMM is trained from test utterances collected from impaired and unimpaired speakers. PV ...

Dermal absorption of topically applied chemicals usually occurs from complex chemical mixtures; yet, most attempts to quantitate dermal permeability use data collected from single chemical exposure in aqueous solutions. The focus of this research was to develop quantitative structure permeation relationships (QSPR) for predicting chemical absorption from mixtures through skin using two levels o...

A three-dimensional, porous electrode composed of reticulated vitreous carbon (RVC) has been examined for the selective removal of metals by electrodeposition from single and multi-component solutions. A three-stage system was envisioned where each metal from a ternary mixture could be selectively removed in each stage. Single and multi-component solutions of copper, nickel, zinc and silver wer...

plete mixture of amino acids resulted in a large suppression of the incorporation. The reason for this effect is also unknown. It may be caused by an imbalance of amino acids since, in a cell-free preparation from E. coli, a balanced mixture of amino acids that reflect the composition of E. coli protein is superior to an equimolar mixture of amino acids. Summary.-A system from developing maize ...
