PRODUCTION OF THE SPANISH VOWEL SYSTEM BY CHINESE SPEAKERS
2018
RESUMEN En este trabajo se comparan los sistemas vocálicos del español y del chino pronunciados por hablantes nativos con el objetivo de presentar a continuación las peculiaridades del sistema vocálico español de un grupo de estudiantes de China con un nivel intermedio de español. El estudio de las similitudes y las diferencias entre los sistemas nativos nos ha permitido prever en qué áreas pueden diferir las vocales pronunciadas por aprendices chinos de las vocales españolas. Los resultados indican que el sistema vocálico español de los estudiantes chinos es estructuralmente similar al sistema nativo, pero con algunas diferencias fonéticas: en primer lugar, tiene una extensión mayor por lo…
Using privacy-transformed speech in the automatic speech recognition acoustic model training
2020
Automatic Speech Recognition (ASR) requires huge amounts of real user speech data to reach state-of-the-art performance. However, speech data conveys sensitive speaker attributes like identity that can be inferred and exploited for malicious purposes. Therefore, there is an interest in the collection of anonymized speech data that is processed by some voice conversion method. In this paper, we evaluate one of the voice conversion methods on Latvian speech data and also investigate if privacy-transformed data can be used to improve ASR acoustic models. Results show the effectiveness of voice conversion against state-of-the-art speaker verification models on Latvian speech and the effectivene…
Esseri di discorso. Su tre attori dell’enunciazione.
2020
The paper aims at explaining the metalinguistic role of three enunciative figures: 1) the speaker (or “sujet parlant”); 2) the locutor; 3) the enunciator.
Yleisten kielitutkintojen arvioijien käsityksiä thainkieliseksi tunnistettujen suomenoppijoiden suullisesta kielitaidosta
2020
Artikkelissa tarkastellaan sitä, miten thainkielisten suomenoppijoiden (N=10) ensikielen tunnistaminen vaikuttaa Yleisten kielitutkintojen (YKI) suomen arvioijien (N=44) käsityksiin kielitaidosta ja millaisia käsityksiä arvioijilla on thainkielisten suullisesta kielitaidosta. Artikkelin aineisto liittyy Rikkinäistä suomea-hankkeeseen, jossa thainkieliset oli yksi tutkimukseen osallistuneesta ensikielen ryhmittymästä. Artikkelissa määrällisen aineiston avulla tarkastellaan tunnistamista ja arvioinnissa käytettyjen kuuden analyyttisen arviointikriteerin käyttöä. Laadullinen aineisto koostuu arvioijien kirjoittamista ensikielen tunnistamiseen ja oppijoiden kielitaitoon liittyvistä huomioista, …
Multivariate nonparametric tests of independence
2005
New test statistics are proposed for testing whether two random vectors are independent. Gieser and Randles, as well as Taskinen, Kankainen, and Oja have introduced and discussed multivariate extensions of the quadrant test of Blomqvist. This article serves as a sequel to this work and presents new multivariate extensions of Kendall's tau and Spearman's rho statistics. Two different approaches are discussed. First, interdirection proportions are used to estimate the cosines of angles between centered observation vectors and between differences of observation vectors. Second, covariances between affine-equivariant multivariate signs and ranks are used. The test statistics arising from these …
Multivariate Nonparametric Tests
2004
Multivariate nonparametric statistical tests of hypotheses are described for the one-sample location problem, the several-sample location problem and the problem of testing independence between pairs of vectors. These methods are based on affine-invariant spatial sign and spatial rank vectors. They provide affine-invariant multivariate generalizations of the univariate sign test, signed-rank test, Wilcoxon rank sum test, Kruskal–Wallis test, and the Kendall and Spearman correlation tests. While the emphasis is on tests of hypotheses, certain references to associated affine-equivariant estimators are included. Pitman asymptotic efficiencies demonstrate the excellent performance of these meth…
Mutations affecting MHC class II binding of the superantigen streptococcal erythrogenic toxin A.
1993
Streptococcal pyrogenic exotoxin A (SPEA) is an important pathogenicity factor of group A streptococci. It is a member of the family of 'superantigens' produced by Staphylococcus aureus and Streptococcus pyogenes, and its T lymphocyte stimulating activity is involved in the pathogenesis of certain diseases caused by pyogenic streptococci. In this study we have generated nine mutant SPEA molecules by substituting amino acids in the regions of homology between different streptococcal and staphylococcal superantigens. An additional mutant was created by deletion of the 10 N-terminal amino acids. The mutants were expressed as fusion proteins. Several mutations led to a loss of function due to a…
Perception and replication of planar sonic gestures
2012
As tables, boards, and walls become surfaces where interaction can be supported by auditory displays, it becomes important to know how accurately and effectively a spatial gesture can be rendered by means of an array of loudspeakers embedded in the surface. Two experiments were designed and performed to assess: (i) how sequences of sound pulses are perceived as gestures when the pulses are distributed in space and time along a line; (ii) how the timing of pulses affects the perceived and reproduced continuity of sequences; and (iii) how effectively a second parallel row of speakers can extend sonic gestures to a two-dimensional space. Results show that azimuthal trajectories can be effectiv…
“The drops which fell from Shakespear’s Pen”: Hamlet in Contemporary Fiction
2012
Questions of gender, ethnicity and sexuality have all been raised by novelists intent on rewriting Shakespeare from the position of what have been seen as cultural margins. While discussions of such rewritings are ongoing, few concerted efforts have been made to trace a pattern in the treatment of Shakespearean allusion and adaptation at the hands of British and American writers of the literary mainstream. The present essay sets out to investigate the way in which three such writers —Ian McEwan, Graham Swift, and John Updike— employ allusion to/adaptations of Hamlet in their novels and what their respective stances reveal about their understanding of their role as canonical writers.
