Voice onset time and speakers' age: data from Hungarian.

Abstract The aim of this paper was to investigate the VOT of voiceless plosives (/p, t, k/) in the speech of Hungarian-speaking elderly. Read speech of 25 old (70 to 90 years) and 25 young (21 to 32 years) was analyzed. In each recording, the VOT of phonologically short [p, t, k] was measured. Our data show that VOT values of all three types of voiceless plosives would exhibit significant differences both in old and in young Hungarians’ speech. Bilabial and alveolar plosives had significantly longer VOT in old subjects’ speech than in that of young subjects, while old subjects produced significantly shorter VOTs in pronouncing [k] than their younger peers. We argue that these results are attributable to (1) significantly slower rate of articulation (yielding longer speech sounds in general), and (2) the articulatory and aerodynamic background of the production of plosives.

Linguistic-phonetic characteristics of cluttering across different speaking styles: A pilot study from Hungarian

Abstract In this study, we investigated the language of Hungarian speakers who clutter (PWCs) in four speaking styles (spontaneous speech, storytelling, deliberately slowed-down speech and giving a talk). The aim of the study was to show the effects of the different speaking styles on the linguistic and acoustic-phonetic patterns of the PWCs’ speech. Grammatical complexity was analyzed in the four speaking styles using a language-specific codification system. The duration and the number of silent pauses and hesitations were measured in order to define both the speech and articulation tempi. The disfluencies and the phonological variability of the words were also analyzed in the four speaking styles. The results supported the view that speaking styles affect the linguistic and phonetic characteristics of cluttering. We found differences in all parameters across speaking styles. These results confirmed our assumption that PWCs are able (1) to express their thoughts using the expected grammatical forms and (2) to articulate similarly to normal speakers. Our results provide more information for better and more precise understanding of cluttering.

Characteristics of pausing in normal, fast and cluttered speech

ABSTRACT One of the main symptoms of cluttering is atypical pausing. However, there is little information about what this atypical pausing means, because typical speakers also have pauses not only at syntactic boundaries, but also within syntactic structures, and even within words. The aim of this study is to analyse how pausing strategies of persons who clutter (PWCs) differ from pausing strategies of normal speakers and speakers with exceptionally rapid speech (ERSs). Results show that there is a difference between the groups in the frequency and/or duration of pauses and the place of their occurrences. ERSs have less and longer pauses than PWCs and control speakers. There is difference between PWCs and control speakers only in the duration of pauses. The results contribute to the assessment, diagnosis, and therapy of cluttering.

Disfluent whole-word repetitions in cluttering: Durational patterns and functions

ABSTRACT In this article, disfluent word-repetitions are analysed in cluttered and control speech. The main questions are the following: (1) Do different functions of word-repetitions occur in different ratio in cluttered and control speech? (2) Are there any differences between PWC and control speakers in durational parameters of disfluent word-repetitions? Results show that there are differences between the two groups of speakers in the types of word-repetitions, and in their durational parameters. In cluttered speech, the most frequent type of repetitions were covert self-repairs while in control speech canonical repetitions are dominated. There were significant differences in the durational parameters of word-repetitions of both groups except in the function of covert self-monitoring. According to the results, it can be concluded that as in earlier studies, analysis of the frequency of types of disfluencies in themselves is not enough as this analysis does not always show the differences between the two groups. It is important to learn more about the durational and functional characteristics of the specific types of disfluencies comparing them in cluttered and control speech.

Clustering of disfluencies in typical, fast and cluttered speech

ABSTRACT Cluttering is a fluency disorder which can be characterised by excessive disfluencies. However, the low number of studies dealing with the analysis of disfluencies in cluttering show contradictory results. The aim of this article is to analyse disfluency clusters in cluttered, fast and typical speech. Frequency of all disfluency clusters and those complex disfluencies which contain more than two constituents were analysed. The number and types of the constituents of complex disfluencies and the reason of their occurrence were analysed in detail. Results show that complex disfluencies occurred the most frequently in cluttered speech, and the least frequently in exceptionally rapid speech (ERS). Persons who clutter (PWC) had more and much longer complex disfluencies than typical speakers. Complex disfluencies which suggest difficulties in linguistic formulation occurred in cluttering significantly more times than in typical speech. The results bring us closer to understanding why there are perceptually more disfluencies in cluttered speech than in typical one. In addition, they also seem to strengthen the notion that cluttering is a language disorder.
