Abstract: A soft magnetic alloy powder includes soft magnetic alloy particles having an amorphous phase. Each of the soft magnetic alloy particles has chemical composition represented by FeaSibBcCdPeCufSngM1hM2i, where M1 is one or more elements of Co and Ni, M2 is one or more elements of Ti, Zr, Hf, Nb, Ta, Mo, W, Cr, Al, Mn, Ag, V, Zn, As, Sb, Bi, Y, and a rare earth element, and 79?a+h+i?86, 0?b?5, 7.2?c?12.2, 0.1?d?3, 7.3?c+d?13.2, 0.5?e?10, 0.4?f?2, 0.3?g?6, 0?h?30, 0?i?5, and a+b+c+d+e+f+g+h+i=100 (parts by mol) are satisfied.

Abstract: A coated soft magnetic alloy particle includes a soft magnetic alloy particle containing an amorphous phase, and a first film containing at least one compound selected from the group consisting of an inorganic compound having a hexagonal, trigonal, or monoclinic crystal structure and a layered silicate mineral. The first film coats a surface of the soft magnetic alloy particle, and an outer peripheral contour of a section of the coated soft magnetic alloy particle has an average smoothness ?_ave of 0.92 or more and 1.00 or less (i.e., from 0.92 or more and 1.00).

Abstract: A method for verification of speaker authentication comprises inputting a test utterance containing a password that is spoken by a speaker, extracting an acoustic feature vector sequence from the inputted test utterance, obtaining a matching path between the extracted acoustic feature vector sequence and a speaker template enrolled by an enrolled speaker, calculating a matching score of the obtained matching path upon considering spectral change of the test utterance and/or spectral change of the speaker template, and comparing the matching score with a predefined discriminating threshold to determine whether the inputted test utterance is an utterance containing a password spoken by the enrolled speaker.
