Ag(+)-exchanged zeolites exhibit unique catalytic properties caused by the combination of their redox and acidic properties. Partial reduction of Ag(+) ions in zeolites with hydrogen leads to the formation of acidic protons and silver metal particles, which can be observed using X-ray powder diffraction patterns (XRD). By simply evacuating hydrogen from the(More)
In this paper we introduce an effective speaker adaptation technique to our unique compact speech recognizer especially designed for consumer electronics products. The compact ASR method we have developed in our previous work employs phoneme similarities as feature parameters, which are extracted temporally successive matching between speech sample and 24(More)
New results are presented concerning the topotactic self-assembly, n-type doping and band-gap engineering of an intrazeolite tungsten(VI) oxide supralattice n(W03)-Na56Y, where 0 < η < 32, built-up of single size and shape (W0 3) 2 dimers. In particular it has been found that the oxygen content of these dimers can be quantitatively adjusted by means of a(More)
In this paper, we propose a new speaker adaptation algorithm that employs vocal tract length normalization (VTLN) with generation-dependent acoustic models, and prove its validity with various generation subjects including small children and aged people. Children and aged people have particular features in their pronunciations. For example, children, whose(More)
We present constrained time alignment acoustic models based on phonetic knowledge and a speaker independent speech recognition method using our proposed models. Japanese syllable and isolated word recognition experiments show that the models have robustness to intraand interspeaker varieties such as acoustic diversity. Furthermore we experiment with word(More)
