We demonstrate the workability of an experimental facility that is geared towards the acquisition of articulatory data from a variety of speech styles common in language use, by means of two synchronized electromagnetic articulography (EMA) devices.

We propose a concatenative synthesis approach to the problem of foreign accent conversion. The approach consists of replacing the most accented portions of nonnative speech with alternative segments from a corpus of the speaker's own speech based on

Recent phonological approaches incorporate phonetic principles in the motivation of phonological regularities, e.g. vowel reduction and neutralization in unstressed position by target undershoot. So far, evidence for this hypothesis is based on impre

Previous studies suggest that there are special timing relations in syllable onsets. The consonants are assumed to be timed, on the one hand, with the vocalic nucleus and, on the other hand, with each other. These competing timing relations result in

Efficient anti-Stokes photoluminescence (PL) has been observed in ${\mathrm{Ga}}_{0.5}{\mathrm{In}}_{0.5}\mathrm{P}$ and GaAs single heterostructure. PL of ${\mathrm{Ga}}_{0.5}{\mathrm{In}}_{0.5}\mathrm{P}$ was observed when photoexciting the ${\math

X-ray diffraction is shown to provide a direct, quantitative, structural measurement of the degree of spontaneous ordering in GaInP. In this paper we combine x-ray diffraction and excitation photoluminescence analyses of CuPt-ordered GaInP, and compa

As many other ternary and quaternary compound semiconductors, GaInP shows natural superlattice ordering consisting of Ga-rich and In-rich (111) crystal planes which causes a strong change of many material properties. This paper presents three example

Circularly polarized excitation light produces spin-polarized excitons in long-range ordered ${\mathrm{Ga}}_{0.5}{\mathrm{In}}_{0.5}\mathrm{P}$ because of a splitting at the valence-band maximum. We observed the spin-relaxation process in ordered ${\

In this article, a comprehensive treatment of the implantation-induced disordering (IID) of CuPtB-ordered GaInP with regard to microstructuring is presented. Ion implantation reduces the thermal stability of the crystal, so that disordering occurs at

The effects of spontaneous ${\mathrm{CuPt}}_{B}$ ordering on the lattice dynamics of ${\mathrm{GaInP}}_{2}$ alloys are studied by room-temperature Raman-scattering experiments on a series of ${\mathrm{GaInP}}_{2}$ samples with various degrees of orde
