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 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 report describes a new approach to obtain specific knowledge about the production of German vowels by Chinese speakers. Experiments have been conducted to acquire both perceptual and acoustic measures of the vowels. 11 Chinese speakers were selected as subjects to read 20 German words. Assessment was conducted by 10 German native speakers. We came up with the conclusion, that the Chinese s...

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...

plant biomass is an important factor for determining arid and semi-aridrangelands capacity. due to the lack of proper and annual sampling of rangelands, there areno suitable data to determine biomass, range condition and proper range managementoperations. plant biomass is one of the measurable attributes that can be assessed inrangeland studies. since the clip and weight method is destructive a...

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 aimed to assess the relative importance of biomechanical and linguistic constraints on articulatory precision by analyzing contextual and token-to-token variability in tongue postioning for vowels. Contextual variability proved greater for lax vowels. Back vowels showed substantially increasing variability towards more front tongue locations. Regarding token-totoken variability, lax ...

The necessity of recognizing handwritten characters is increasing day by because its various applications. objective this paper to provide a sophisticated, effective and efficient way recognize classify Bangla characters. Here an extended convolutional neural network (CNN) model has been proposed Our CNN tested on “BanglalLekha-Isolated” dataset where there are 10 classes for digits, 11 vowels ...

Languages differ in the constitution of their phonemic repertoire and in the relative distinctiveness of phonemes within the repertoire. In the present study, we asked whether such differences constrain spoken-word recognition, via two word reconstruction experiments, in which listeners turned non-words into real words by changing single sounds. The experiments were carried out in Dutch (which ...
