Aging affects temporal characteristics of speech. It is still a question how these changes occur in different speech styles which require various cognitive skills. In this paper speech rate, articulation rate, and pauses of 20 young and 20 old speakers are analyzed in four speech styles: spontaneous narrative, narrative recalls, a three-participant conversation, and reading aloud. Results show that age has a significant effect only on speech rate, articulation rate, and frequency of pauses. Speech style has a higher effect on temporal parameters than speakers' age.

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.

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.

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 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 persons who clutter (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.
