To clarify the neural substrates and their dynamics during crossmodal association learning, we conducted functional magnetic resonance imaging (MRI) during audiovisual paired-association learning of delayed matching-to-sample tasks. Thirty subjects were involved in the study; 15 performed an audiovisual paired-association learning task, and the remainder completed a control visuo-visual task. E...

This study examined dual task performance in 28 younger (18-30 years) and 28 older (>60 years) adults using two sets of choice reaction time (RT) tasks paired with digit tasks. Set one paired simple choice RT with digit forward; set two paired complex choice RT with digit backward. Each task within each set had easy and hard conditions. For the simple choice RT, participants viewed single lette...

Although numerous examples of sound symbolism exist in spoken language, little is known about whether listeners recognize and utilize these non-arbitrary relationships between sound and meaning to guide their interpretation of novel words. The present experiments examined the extent to which listeners are able to constrain meaning solely on the basis of the segmental sound structure of language...

Listeners posses a remarkable ability to attend to one of two speakers speaking at the same time (simultaneous speakers). The present research studied the role of speech rhythm involved in this process. In two experiments with the Coordinate Measure Response Corpus, listeners were asked to attend to one of two simultaneous speakers. In Experiment I native and French accented speakers of English...

We study the problem of multimodal dimensionality reduction assuming that data samples can be missing at training time, and not all data modalities may be present at application time. Maximum covariance analysis, as a generalization of PCA, has many desirable properties, but its application to practical problems is limited by its need for perfectly paired data. We overcome this limitation by a ...

In March 2020, schools in the Kingdom of Saudi Arabia were suspended. Online learning became a substitute for traditional face-to-face learning. This study addresses implications this shift attitudes university-level English majored students taking listening and speaking course. The investigated students’ towards: a) importance English; b) teachers use emails to communicate their feedback on En...

BACKGROUND Quality and frequency variability of adolescents' voice, during puberty, in different phonation tasks. AIM To analyze the vocal stability of adolescents in three different phonation tasks using a voice perceptual analysis. METHOD Participants were male students (n = 46 individuals), ranging in age from 13 to 15 years, from a public school in Campinas--SP. Voice samples were recor...

This paper examines techniques that allow a well-trained source system built on one task to be rapidly adapted, or ported, to another target task. The two tasks considered in this paper are Hub5, or Switchboard, as the source system and VoiceMail as the target task. The two tasks are acoustically similar, both being telephonebandwidth speech tasks, but differ in speaking style. SwitchBoard is c...

In Brain-Computer Interface (BCI) research, subject and session specific training data is usually used to ensure satisfying classification results. In this paper, we show that neural responses to different speaking tasks recorded with functional Near Infrared spectroscopy (fNIRS) are consistent enough across speakers to robustly classify speaking modes with models trained exclusively on other s...

This paper attempts to quantify differences in speaking rates in first and second languages, in the context of the growth of English as a lingua franca, where more L2 speakers than ever before are using English to perform tasks in their working environments. One such task is the oral presentation. The subjects in this study were fourteen fluent English second language speakers who held the same...
