Primary lexical stress is realised differently in English and Welsh. English lexical stress involves greater vowel duration in the associated syllable, whereas Welsh involves the shortening of the vowel associated with the stressed syllable and the lengthening of the immediately following consonant. Some accounts have suggested that Welsh English also features this long post-stress consonant. T...

The challenge of speech modification is to flexibly modify the speech without degrading speech quality. The conventional methods are limited by their inability to flexibly control speech signals in time and frequency domains. This causes degradation of the quality of modified speech. This paper proposes a highquality analysis/synthesis method for speech modification. To control the temporal evo...

One of the ways to gauge your own exercise intensity while running, is to assess your capability of talking while running: if you can still speak comfortably, you are running within the recommended intensity guidelines. This subjective way of estimating one’s exercise intensity by talking (i.e. the Talk Test) motivated us to investigate how speech characteristics are affected during running and...

A study was undertaken to determine differences between jitter and shimmer in voices of children with different syndromes. Voices of 60 children, both sexes, aged 7-12 years were analysed by EZ Voice Analysis Software (program for jitter and shimmer measuring). The main purpose of this paper has diagnostic background. Obtained results show, which acoustical indicators of pathological voice are ...

The major debate on primary stress assignment in Brazilian Portuguese (BP) concerns whether it is lexically given or predictable by a set of principles. This paper presents a contribution to this debate by suggesting a usage-based approach to stress assignment in BP. It is argued that stress assignment is better accounted for as the result of generalizations over exemplars, and these generaliza...

This paper presents the results of a pilot study of stress interval durations in Greek and Russian. Native speakers of each language were recorded producing utterances in which the number of syllables between stressed syllables varied. The results showed a noticeable tendency towards isochrony in Greek but not in Russian, according to which there is an inverse relation between the number of syl...
