Data from three acoustic cues to stop voicing is analyzed for the effect of phrasal accent in a corpus of read radio news speech from a single speaker of American English. The results show that VOT, Closure Duration and F0 are significant cues to voicing for stops in this corpus, though the acoustic patterns vary by place of articulation. There is a significant effect of phrasal accent on each ...

In hidden Markov model-based speech synthesis, speech is typically parameterized using source-filter decomposition. A widely used analysis/synthesis framework, STRAIGHT, decomposes the speech waveform into a framewise spectral envelope and a mixed mode excitation signal. Inclusion of an aperiodicity measure in the model enables synthesis also for signals that are not purely voiced or unvoiced. ...

Early assessment of phonetic and phonological development requires knowledge of typical versus atypical speech patterns, as well as the range of individual developmental trajectories. The nature of data reporting in previous literature on typical voicing acquisition left aspects of the developmental process unclear and limited clinical applicability. This work extends a previous four-month grou...

It is generally assumed that the phonetic categories of speech are not indissoluble wholes, but rather can be characterized in terms of a bundle of phonetic or distinctive features. These features may be defined in terms of either acoustic or articulatory attributes of the speech signal. However, it is also the case that at least from an acoustic or perceptual point of view, each of these phone...

The use of climate engineering or geoengineering technologies to combat climate change has been a controversial topic, even in the scientific debate. In recent studies, it has been claimed that the debate on climate engineering technologies may be closing down prematurely, with detrimental effects on the possibility of social and ethical reflection in appraising these controversial technologies...

Examining articulatory compensation has been important in understanding how the speech production system is organized, and how it relates to the acoustic and ultimately phonological levels. This paper offers a method that detects articulatory compensation in the acoustic signal, which is based on linear regression modeling of co-variation patterns between acoustic cues. We demonstrate the metho...

This study examines the phonetic characteristics of primary versus secondary stress on the first syllables of the surname ‘Wheateron’ and related adjective ‘Wheateresque’ in postnuclear, deaccented position in a dialogue produced 40 times by 3 Australian English talkers. Synchronised acoustic, electromagnetometer, and electropalatographic recordings were analysed. One subject had a higher F0 in...

Phonological alternations often serve to modify forms so that they respect a phonotactic restriction that applies across the language. For example, the voicing alternation in the English plural produces word-final sequences that respect the general ban against a voiceless obstruent followed by a voiced one. Since Chomsky and Halle [1], it has been assumed that an adequate theory of phonology sh...

Syllable-onset /l/ in British English is longer and often has different (usually lower) F2 frequency before a voiced coda. Five experiments explore the perceptual power of these properties and of f0. In each experiment, listeners identified as led or let synthetic syllables whose latter half was replaced by noise. The most reliable cue was /l/ duration; F2 frequency in the /l/ was influential m...

We report on an English-speaking, aphasic individual (TB) who showed a striking dissociation in speaking with the different forms (allomorphs) that an inflection can take. Although very accurate in producing the consonantal inflections (-/s/, -/z/, -/d/, -/t/), TB consistently omitted syllabic inflections (-/əz/, -/əd/), therefore correctly saying "dogs" or "walked," but "bench" for benches or ...
