The Acquisition of Hungarian High Front Unrounded Short vs. Long Vowels
نویسندگان
چکیده
This study examined spectral properties of the Hungarian vowel pair /i/ vs. /i:/ with contrasting phonemic vowel lengths in 2;0 and 4;0 years old boys acquiring Hungarian as their native language. Results were obtained by an automated pitchsynchronous bandfilter analysis method that estimates the spectral envelope representation of vowels. Subsequent data reduction was achieved via principal component analysis. Findings show that 4;0 years old boys produce more peripheral vowels, due partly to an increased lip-jaw coordination ability. Additionally, the vowel space of older children contains more compact vowel spaces corresponding to each vowel. Spectral features of /i/ vs. /i:/ differ in 4;0 years old as opposed to 2;0 years old boys.

The effects of lip rounding on voice onset time production in children acquiring Hungarian
The goal of this project was to examine the effects of lip rounding on the production of voice onset time in voiceless bilabial stops in children acquiring Hungarian as their first language. The duration of voice onset time in stops followed by or embedded between high back rounded phonologically long vowels with prominent lip protrusion are considerably longer. VOT durations in stops followed ...
متن کاملVowels in regional variants of Danish
This paper presents the results of an acoustic investigation of the vowel sounds in three regional variants of Danish in spontaneous speech. The material for elicitation represents a conceptual fusion of word lists and interviews. A total of 18 subjects from three regions have been analysed. The expected regional differences have not been found. We find, however, clear indications that a genera...
متن کاملDomain-initial strengthening on French vowels and phonological contrasts: Evidence from lip articulation and spectral variation
Domain-initial strengthening has primarily been studied for consonants. This paper examines whether vowels also undergo boundary-induced phonetic variation and questions how this effect interacts with phonological contrast in a dense vowel system such as that of French. The labial articulation and the acoustic properties of the 10 French oral vowels /i, e, ɛ, a, y, ø, œ, u, o, ɔ/ are examined i...
متن کاملRelation of formants and subglottal resonances in Hungarian vowels
The relation between vowel formants and subglottal resonances (SGRs) has previously been explored in English, German, and Korean. Results from these studies indicate that vowel classes are categorically separated by SGRs. We extended this work to Hungarian vowels, which have not been related to SGRs before. The Hungarian vowel system contains paired long and short vowels as well as a series of ...
متن کاملQuantity Distinction in the Hungarian Vowel System—just Theory or Also Reality?
According to most current theories, the Hungarian vowel system involves 14 vowels that correspond to seven vowel pairs, each differentiated by quantity. However, there are phenomena both on the phonological and the phonetic level which suggest that for low, mid, and high vowels a separate evaluation of the quantity opposition is necessary. In order to test this, we conducted a perception test, ...
