in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
Running Head: Perceptual contributions of the consonant-vowel boundary ____________ a) Portions of the data were presented at the 154 th meeting of the Acoustical Society of Perceptual contributions of the consonant-vowel boundary 2 ABSTRACT Although research has focused on the perceptual contribution of consonants to spoken syllable or word intelligibility, for sentences, vowels have a distinc...
The aim of our work is to increase the intelligibility of speech in noise by modifying regions of the signal that contain acoustic cues to consonant identity in order to make it more resistant to subsequent degradation. Two instances of each of 36 vowelconsonant-vowel (VCV) stimuli comprising the consonants D F I R V M H X U \ O P in the context of the vowels # K W were recorded by two male and...
This paper presents the experimental evaluation for recognition of consonant-vowel (CV) units under noise. Noise is one of the common degradation in real environments which strongly effects the performance of speech recognition system. In this work, initially effect of noise on recognition of CV units is studied by using two-stage CV recognition system proposed in our earlier studies. Later spe...
this study examined the phonetic characteristics of persian sentence stress produced by native mandarin chinese speakers. we compared the phonetic correlates of sentence stress, namely fundamental frequency (f0), vowel duration, and vowel intensity in the production of 8 mandarin chinese speakers and 8 native persian speakers. results indicated that mandarin chinese speakers of persian could di...
power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
the ability of composing a coherent and extended piece of writing in second language is considered as a fundamental factor to convey information and ideas of learners through the academic issues. although learners may achieve a perfect academic writing skill through assigning the l2 tasks in content based instruction, but demonstration of their abilities may be related to their ability in l1 es...
Channel vocoders using either tone or band-limited noise carriers have been used in experiments to simulate cochlear implant processing in normal-hearing listeners. Previous results from these experiments have suggested that the two vocoder types produce speech of nearly equal intelligibility in quiet conditions. The purpose of this study was to further compare the performance of tone and noise...
monumental changes occurring on a daily basis have altered the world into a global village of expanding technology and shrinking geography in which preparing language learners for intercultural communication seems to be a sine qua non for modern language education. employing a cross-sectional design in its first phase, this study investigated the intercultural sensitivity and language proficien...
This study investigated the dynamic spectral patterns of vowels in Mandarin Chinese using a corpus of monosyllabic words spoken in isolation. Mel-frequency cepstral coefficients (MFCCs) were parameterized in different ways to test the nature of the dynamic information in vowels through automatic vowel classification. Compared to the MFCCs extracted at the vowel midpoint, using the MFCCs extract...
