Objective: Vowels are the center of syllables while formant structures are one of the most important acoustic characteristics of speech sounds that help in their articulatory and perceptual aspects. Formants represent the shape and size of the vocal tract. There exist trivial differences between the vocal tracts of different people due to which the formant structures of a vowel in one person ar...
In this paper, we study human perception of consonants in the presence of additive babble noise at two speaking rates. In addition, we work on a model that attempts to replicate these human results through a phoneme recognition model. Consonant-Vowel-Consonant (CVC) stimuli comprising of a set of 13 consonants and 3 vowels (/a/, /i/, /u/) were recorded in a sound proof booth by two talkers at t...
Many studies have shown the advantage of using ideal binary mask (IdBM) to improve the intelligibility of speech masked by interfering voices. The present work further investigated the segmental contribution to the intelligibility of the IdBMprocessed sentences. Three types (i.e., vowel-only, consonantonly, and vowel-consonant transition) of Mandarin IdBMprocessed stimuli were generated by usin...
Speech perception depends on the auditory system's ability to extract relevant acoustic features from competing background noise. Despite widespread acknowledgement that noise exacerbates this process, little is known about the neurophysiologic mechanisms underlying the encoding of speech in noise. Moreover, the relative contribution of different brain nuclei to these processes has not been ful...
Japanese vowel devoicing was investigated from the viewpoint of perception, an approach which has not been taken in any previous studies. It appears in some dialects of Japanese, including Tokyo dialect. Three tests, a vowel preference test, a same/different test, and an inter-stimulus interval effect test were performed. In the vowel preference tests, 46.3% of devoiced vowel dialects speakers ...
abstract the present study was an attempt to investigate the effect of critical thinking on writing ability of 60 iranian intermediate efl learners studying at chenar language institute in khuzestan, iran. to this end, the participants of the study were selected based on their performance in an pet test, a cornell critical thinking test form x and a pre-test of writing. the participants un...
within communicative, interactive, and learner-centered framework of language teaching and learning, students need to learn four skills of listening, speaking, reading, and writing for their educational success. but of all the language skills, reading enjoys a paramount significance in so many second or foreign language academic contexts. in spite of its importance, language learners still have...
In this article, the low back vowel /A/ in word-final positions in Eghlidian dialect, one of Persian dialects, is studied. This vowel is represented phonetically as [A], [o] and [@] in different phonetic environments. Therefore many words were collected via interviewing ten native speakers so that these different alternant forms can be accounted for appropriately. Since one of the authors of th...
introduction: the feedback provided by auditory apparatus equips normal hearing people with an important controlling mechanism over the speech production processes. the speech of hearing-impaired children is both perceptually and acoustically abnormal. this study tried to compare the formant frequencies of three long vowels in persian-speaking children who used cochlear implant and those who we...
