Bulgarian vowel reduction in unstressed position: An ultrasound and acoustic investigation

  title={Bulgarian vowel reduction in unstressed position: An ultrasound and acoustic investigation},
  author={Marie Dokovova and Mitko Sabev and James M. Scobbie and Robin J. Lickley and Steve Cowen},
Vowel reduction in Contemporary Standard Bulgarian (CSB) has been variously claimed to involve raising, no change or lowering of the high vowels /iəu/. There is a general agreement that the low vowels /ɛaɔ/ are raised when unstressed. This paper directly measures tongue height using Ultrasound Tongue Imaging (UTI) and relates this measure to the acoustic correlate F1 at vowel midpoint. The six vowels of CSB were paired with respect to frontness (/ɛ, i/, /a, ə/, /ɔ, u/), and the overlap in…

The age effects on EP vowel production: an ultrasound pilot study

The preliminary results suggest that the vowel articulatory space, namely for disyllabic sequences, tend to be smaller in the older females in the European Portuguese native female speakers.

Contributions to a Quantitative Unsupervised Processing and Analysis of Tongue in Ultrasound Images

This work describes the first results of an automatic tongue segmentation method from US, along with a characterization of the main challenges posed by the images, and can provide the required data for an automatic analysis of maximum tongue height, a relevant parameter to assess speech changes on vowel production.

A cosine-weighted FDA as well as an automatically weighted FDA in which weights are found automatically are proposed in the feature space to establish a weighted kernel FDA for both existing and newly proposed weights.



Reduction of unstressed central and back vowels in Contemporary Standard Bulgarian

The results reveal a less unequivocal picture of the pairwise convergence of formant frequencies than has previously been reported: the data confirm a high degree of acoustic overlap only for the unstressed back vowels, whereas the differences in the unstress central vowels remain statistically significant.

The bulgarian stressed and unstressed vowel system. a corpus study

Results confirm the raising of unstressed /a/ and /ɔ/ reported previously, but raising is found to affect all vowels when unstressed except /i/, and the mechanism underlying the reduction process is discussed.

Head-Probe Stabilisation in Ultrasound Tongue Imaging Using a Headset to Permit Natural Head Movement

Translation and rotation movements of an ultrasound probe relative to the speaker’s head induce error. We examine one means of reducing such errors, the headset stabilising system made by
