Introduction Segregation phenomena are often studied using the "double-vowel" identification task: subjects are presented with stimuli containing two vowels, and requested to identify both of them [1]. The number of trials on which both vowels are correctly identified (combinationcorrect score) is used as a measure of segregation. This technique has several drawbacks: a) The task is often too e...

In this paper we analyzed some of the phonological rules of Russian loanword adaptation in Persian, on the view of Optimal Theory (OT) (Prince and Smolensky, 1993, 2003). It is the first study of phonological process on Russian loanwords adaptation in Persian. By gathering about 50 current Russian loanwords, we selected some of them to analyze. We found out that vowel insertion, vowel prothesis...

This study examined the vowel production of an individual with aphasia and accompanying apraxia of speech during both imitation and reading tasks producing CVC syllables within a carrier phrase. Listener judgments revealed a predominance of errors for the short, front vowels // and // for both conditions. Although duration measures of perceptually correct productions revealed a relatively pre...

This paper presents an unsupervised approach to Automatic Language Identification (ALI) based on vowel system modeling. Each language vowel system is modeled by a Gaussian Mixture Model (GMM) trained with automatically detected vowels. Since this detection is unsupervised and language independent, no labeled data are required. GMMs are initialized using an efficient data-driven variant of the L...

abstract objective: this study aimed to present a descriptive analysis of the responses given by two-and-a-half year-old farsi-speaking children to the “persian picture naming test” carried out on a statistically significant sample of subjects. materials and methods: 60 two-and-a-half-year-old children were chosen from 32 kindergartens through multiple cluster sampling method and then evaluated...

Discrimination was investigated because this fact...

this article addresses the perceptual correlates of compensatory lengthening in persian. in a perception experiment, duration, spectral tilt measurements h1-h2 and h1-f1 and f0 were varied in several steps based on the results from a production experiment (sadeghi, 2007). subjects were asked to identify the tokens involving vowel length. results revealed that duration is the most reliable perce...
