Vowel normalization in speech perception was investigated in three experiments. The range of the second formant in a carrier phrase was manipulated and this affected the perception of a target vowel in a compensatory fashion: A low F2 range in the carrier phrase made it more likely that the target vowel was perceived as a front vowel, that is, with a high F2. Recent experiments indicated that t...

We developed a method and a system for facial expression recognition of a speaker using vowel judgment and features of a thermal face image. In this study, a speech recognition system saves thermal images at the three timing positions of just before speaking, and just when speaking the phonemes of the first and last vowels. The face direction is estimated to select front-view faces as the targe...

This paper presents the results of two high variability phonetic training regimes aimed at improving the perception of five English vowels, namely /æ, ʌ, ɪ, i, ɜː/ by Spanish/Catalan speakers learning English as a second language (L2). 60 learners of English as an L2 took part in a pretest/training/post-test study and were assigned to one of two training methods (forced-choice identification tr...

A computational modeling study was conducted using multinomial logistic regression to predict whether exposure to an unfamiliar regional accent of English would influence vowel categorization in (1) the exposure accent, (2) the native accent, and (3) another unfamiliar accent. We manipulated the number of talkers in the exposure data to determine whether talker variability influenced the effica...

OBJECTIVE To determine the effect of reduced dynamic range on speech understanding when the speech signals are processed in a manner similar to a 6-channel cochlear implant speech processor. DESIGN Signals were processed in a manner similar to a 6-channel cochlear implant processor and output as a sum of sine waves with frequencies equal to the center frequencies of the analysis filters. The ...

In this paper, we discuss the issues in automatic recognition of vowels in Persian language. The present work focuses on new statistical method of recognition of vowels as a basic unit of syllables. First we describe a vowel detection system then briefly discuss how the detected vowels can feed to recognition unit. According to pattern recognition, Support Vector Machines (SVM) as a discriminat...

CONTEMPORARY ISSUES IN COMMUNICATION SCIENCE AND DISORDERS • Volume 28 • 20–29 • Spring 2001 © NSSLHA 1092-5171/01/2801-0020 ABSTRACT: Spoken word recognition was investigated in a group of children aged 3:0 to 7:11 (years:months) to assess the relationship between five measures of language development and spoken word recognition accuracy. Two spoken word recognition tasks, gated words and nois...

Czech vowels in fluent speech and their parameters can be found by The Generation and Analysis of Vowel Polygons software. On the base of found vowels formant values, vowel polygons can be created and further analyzed as a unit in relevant formant planes. Phoneme recognition is based on pattern similarity using Mahalanobis distance and Feed-forward Neural Network, and it is expanded by time dur...
