In this study we investigated the durational correlates of lexical stress and pitch accent at normal and fast speech rate in Dutch. Previous literature on English shows that durations of lexically unstressed vowels are reduced more than stressed vowels when speakers increase their speech rate. We found that the same holds for Dutch, irrespective of whether the unstressed vowel is schwa or a 慺ul...

The usefulness of dynamic formant properties for speaker discrimination was demonstrated on English, mostly exploiting long vowels or diphthongs, characterized both by actual measures along the formant tracks and coefficients from polynomial regression on these tracks. This study applies this paradigm to Czech, using less tightly controlled (more forensically realistic) material and taking into...

This paper investigates style differences in the distribution of Dutch diphthongal vowels over the acoustic vowel space. It aims to find out whether a paradox that arises in monophthongs, i.e. that variation between vowels decreases in informal speech and variation within vowels increases without a loss of identifiability, is also found for diphthongal vowels. Our data reveal only a partial par...

This study deals with data about the acoustic properties of nasal vowels of the Twi language, spoken in Ghana, compared to the oral counterparts. Evidence from our data shows a general tendency whereby F2 and F3 of the nasal vowels are lower than the oral counterparts in both the short and long contexts. Acoustic data also reveal that nasal-oral contrast depends on the vowel type. Nasal vowels ...

This paper presents an acoustical analysis of vowels in a Northern Australian language, Gupapuyngu, in order to investigate whether vowels in CVCV words differ according to prosodic prominence and word position. It is shown that back vowels are produced with a narrower constriction when prosodically prominent and word-initial. However, in general, vowels tend not to be hyperarticulated under co...

This paper presents multi-font/multi-size Kannada numerals and vowels recognition based on spatial features. Directional spatial features viz stroke density, stroke length and the number of stokes in an image are employed as potential features to characterize the printed Kannada numerals and vowels. Based on these features 1100 numerals and 1400 vowels are classified with Multi-class Support Ve...

The aim of the present paper is to study the status of the short vowels /i/ and /u/ in five selected Iranian Balochi dialects. These dialects are spoken in Sistan (SI), Saravan (SA), Khash (KH), Iranshahr (IR), and Chabahar (CH) regions located in province Sistan va Baluchestan in the southeast of Iran. This study investigates whether these two vowels have the same qualities as the short /i/ an...
