Anshuman has documented the use of the vowel signs for ai and au as secondary vowel markers for diphthongs. Conceptually, they are used “in addition to” the vowel markers for the basic vowel signs since obviously the vowel they denote comes in second place. Thus in encoding all these diphthongs, Anshuman suggests the placement of the secondary vowel marker after the representation of the primar...

careful analysis of the ferdows persian accent showed that the back vowel /a/ changes to front vowel [a] in the first syllable of bi-syllabic words and in the second syllable of tri-syllabic words. however, this does not occur in the last syllable. it was also found that different processes occur before nasals; /a/ changes to [o] before /m/. but before /n/, it changes to [a] in the penult of ...

This paper investigates how different syllable affiliations of intervocalic /st/ cluster affect vowel-to-vowel coarticulation in English. Very few studies have examined the effect of syllable structure on vowel-to-vowel coarticulation. Previous studies show that onset and coda consonants differ acoustically, articulatorily, perceptually and typologically. Onsets are stronger, more stable, more ...

In this study, the Vowel-to-Vowel (V-to-V) coarticulatory effect in the Vowel-Consonant-Vowel (VCV) sequences is investigated, and the F2 offset value of the first vowel is analyzed. Results show that, in the trans-segment context, anticipatory coarticulation exists in Chinese. Due to high articulatory strength of aspirated obstruents, in the context of subsequent vowel /i/, the V1 F2 offset va...

Research on language-specific tuning in speech perception has focused mainly on consonants, while that on non-native vowel perception has failed to address whether the same principles apply. Therefore, non-native vowel perception was investigated here in light of relevant theoretical models: the Perceptual Assimilation Model (PAM) and the Natural Referent Vowel (NRV) framework. American-English...

According to a recent hypothesis, the CV pattern (i.e., the arrangement of consonant and vowel letters) constrains the mental representation of letter strings, with each vowel or vowel cluster being the core of a unit. Six experiments with the same/different task were conducted to test whether this structure is extracted prelexically. In the mismatching trials, the targets were pseudowords buil...

This paper reviews the historical development of phonetic vowel systems from 1617 to 2005. In times where the vowel system of the International Phonetic Alphabet (IPA) is the de facto standard in phonetic sciences it is important to learn more about predecessors and alternative considerations of how vowel systems could be organized. This concerns matters of transcriptions, ideas on parameters o...

Earlier work [Nittrouer et al., J. Speech Hear. Res. 32, 120-132 (1989)] demonstrated greater evidence of coarticulation in the fricative-vowel syllables of children than in those of adults when measured by anticipatory vowel effects on the resonant frequency of the fricative back cavity. In the present study, three experiments showed that this increased coarticulation led to improved vowel rec...
