This paper focuses on teaching the use of indefinite articles ‘a’ and ‘an’ appropriately to students who have had their schooling from Hindi medium schools are presently pursuing bachelor diploma courses. It was seen that these fail correct before English words because lack knowledge consonant vowel sounds in language, further solve this issue a technique introduced where they could prior assoc...

The objective and subjective classification of unvoiced stop consonants in varying vowel contexts were studied. The objective classification was based on auditory feature vectors obtained by warped linear prediction (WLP) and vector autoregressive (VAR) models for parameter trajectories. In the case of known vowel the unvoiced consonants were classified 98-100% correctly based on the auditory s...

introduction: on the importance of the formant frequency, it is enough to say that the first three formants of a vowel and their internal relationships are the major components in detection of vowel type by listener. moreover, the quality of a vowel depends on its factorial frequencies. the main application of measuring factorial frequency is for description of vowel errors because recognizing ...

Ten listeners were asked to identify and rate the quality of speech sounds processed in such a way that only the most energetic spectral components were retained. The influence of both the number of retained spectral components and of the width of the frequency bands surrounding these components was studied. The sounds consisted of vowel-consonant-vowel stimuli produced by two male and two fema...

This article presents the results of an acoustic analysis of vowels and plosives/affricates produced by 45 Mandarin-speaking children with hearing impairment. Vowel production is represented and categorized into three groups by vowel space size calculated with normalized F1 and F2 values of corner vowels. The correlation between speech intelligibility and language abilities assessed by the leve...

Discrimination of vowel duration was explored with regard to JNDs, error bias, and effects of modality and consonant context. 90 normal-hearing participants discriminated either auditorily, visually, or audiovisually between pairs of stimuli differing with regard to duration of the vowel /a/. Duration differences varied in 24 steps: 12 with the first token longer and 12 with the second token lo...

This study explored whether an identity-matching-based stimulus equivalence procedure could be used to teach vowel and consonant stimulus classes to 2 adolescent females with moderate mental retardation. Delayed match-to-sample trials presented a compound sample stimulus consisting of printed letters and a spoken word ("vowel" or "consonant"). The correct comparison stimulus matched only one of...

A vowel training aid system for hearing impaired persons which uses a Windows-based multimedia computer has been developed. The system provides two main displays which give visual feedback for vowels spoken in isolation and short word contexts. Feature extraction methods and neural network processing techniques provide a high degree of accuracy for speaker independent vowel training. The system...

In English, the feature [tense] or [ATR] (advanced tongue root) has been used to encompass the vowels that are produced on the extreme edges of the acoustic and articulatory spaces. The lax counterparts to these vowels are generally produced closer to the center of those spaces. The present study is based on the hypothesis that the extreme positioning in both articulatory and acoustic space evo...
