This paper concerns the development of a system for the recognition of a context or an environment based on acoustic information only. Our system uses mel-frequency cepstral coefficients and their derivatives as features, and continuous density hidden Markov models (HMM) as acoustic models. We evaluate different model topologies and training methods for HMMs and show that discriminative trainin...

PURPOSE The purpose of the present study was to examine the effect of minimal hearing loss (HL) on children's ability to perform simultaneous tasks in quiet and in noise. METHOD Ten children with minimal HL and 11 children with normal hearing (NH) participated. Both groups ranged in age from 8 to 12 years. The children categorized common words (primary task) while completing dot-to-dot games ...

Foreign language learners typically experience considerable anxiety about taking listening tests. This study investigated how four forms of listening support (pre-teaching of content and vocabulary, question preview, and repeated input) affect the anxiety levels of college students in Taiwan taking a multiple-choice achievement test, which counts for their final grade in a required listening co...

161 Abstract— Recently, According to increasing interest to original sound Karaoke instrument, MIDI type karaoke manufacturer attempt to make more cheap method instead of original recoding method. Separating technique for singing voice from music accompaniment is very useful in such equipment. We propose a system to separate singing voice from music accompaniment for stereo recordings. Our syst...

abstracttask-based language teaching is considered an effective way to achieve a harmony between grammar and communication. the present study investigates two different ways of teaching modal verbs: task-based versus traditional approaches. to this purpose, an oxford placement test was administered to select 40 homogeneous participants out of a larger population who took this test. the selected...

with regard to the impossibility of preparing learners for each situation that they might encounter in their life, it is more logical to teach them how to cope with unexpected challenges. helping learners ‘learn how to help themselves’ can be facilitated by means of tasks and activities in the classroom context. this paper presents some of the find- ings of a study on iranian young learners bet...

OBJECTIVES To undertake a systematic review of available evidence on the effect of hearing impairment and hearing aid amplification on listening effort. Two research questions were addressed: Q1) does hearing impairment affect listening effort? and Q2) can hearing aid amplification affect listening effort during speech comprehension? DESIGN English language articles were identified through sy...

An extension of the auditory module in EPIC is introduced to model the two-talker coordinate response measure (CRM) listening task. The construct of an auditory stream is employed as an object in the working memory of EPIC’s cognitive processor. Production rules are developed that execute the two-talker CRM task. Analysis of these rules reveal two sources of possible error in the output of the ...
