The influence of top-down expectations on the perception of syllable prominence

Arnold D, Wagner P. The influence of top-down expectations on the perception of syllable prominence. In: Proceedings of the 2nd ISCA Workshop on Experimental Linguistics (ExLing 2008). 2008: 25-28.In our study we use the experimental framework of priming to manipulate our subjects‘ expectations of syllable prominence in sentences with a well-defined syntactic and phonological structure. It shows that it is possible to prime prominence patterns and that priming leads to significant differences in the judgment of syllable promi- nence. Key words: Top-Down, Priming, Syllable Prominence, Perceptio

Prominence in Indonesian Stress, Phrases, and Boundaries

Many (Western) languages have word-based stress, which entails that one, predictable syllable per word is more prominent than all the other syllables in that word. Some linguists claim that such stresses also occur in Indonesian. In this article, we set out to investigate that claim using experimental, phonetic methods. The results confirm our hypothesis that Indonesian lacks word-based stress. Yet, we do observe some kind of prominence pattern. In the last part of this article, we search for the phonological phenomenon that generates this pattern, exploring the level of the phrase to see whether phrasal accents or boundary markers are likely candidates

Great Expectations - Introspective vs. Perceptual Prominence Ratings and their Acoustic Correlates

Wagner P. Great Expectations - Introspective vs. Perceptual Prominence Ratings and their Acoustic Correlates. In: Interspeech 2005. 2005: 2381-2384.In order to gain knowledge about the interaction between top-down expectations of listeners concerning prosodic prominence and its acoustic correlates, two exploratory empirical studies were carried out. First, native and non-native subjects rated prominences of speech read at normal and very fast - prosodically very different - speech. Later, these ratings were compared with introspective prominence ratings of different listeners. First results indicate a major influence of the introspection on prominence ratings, especially if acoustic cues are difficult to interpret, as it is the case in very fast speech. Compared to native subjects, non-natives rely less on their introspection and more on the acoustics

Production, perception and online processing of prominence in the post-focal domain

This dissertation presents a fundamentally new and in-depth investigation of the distribution of prominence in different focal structures in two varieties of Italian (the one spoken in Udine and the one spoken in Bari), by means of the implementation of a categorical analysis with the continuous prosodic parameters related to F0 and periodic energy. Results provide evidence of the fact that prominence in these varieties of Italian is conveyed by both a categorical three-way distinction and a gradual modulation: absence or presence of pitch movement in the distinction between background (post-focal position) and the focal conditions, and a gradual modification of energy and duration. The degree of prominence of words occurring in different focal structures was also investigated in perception. The reportedly different distribution of prominence found in questions for the variety of Italian spoken in Bari is shown to have an influence in the degree of perceived prominence. This influence is found in the comparison between prominence’s ratings of Bari and Udine native speakers, as well as of Bari native speakers and German native speakers, with Italian as L2. Furthermore, the present dissertation tests the real-time processing of the pitch excursion registered in the post-focal region of questions in the Bari variety. Findings confirmed that the fine-grained changes in prominence are processed in real time. Moreover, results indicate that top-down expectations play a crucial role in modulating general cognitive processes. Overall, this thesis supports the view of prosodic prominence as characterised by a bundle of cues, probabilistically distributed in the listener’s perceptual space, which form top-down expectations that play a role both in offline perception and in online processing. Signal-based factors also play a role in perception and online processing, but can however be overridden by expectations

The effect of priming on the correlations between prominence ratings and acoustic features

Arnold D, Wagner P, Möbius B. The effect of priming on the correlations between prominence ratings and acoustic features. In: Prosodic Prominence: Perceptual and Automatic Identification (Speech Prosody 2010 Workshop). 2010: W1.02.In previous research we showed that the priming paradigm can be used to significantly alter the prominence ratings of subjects. In that study we only looked at the changes in the subjects’ ratings. In the present study, we analyzed the acoustic parameters of the stimuli used in the priming study and investigated the correlation between prominence ratings and acoustic parameters. The results show that priming has a significant effect on these correlations. The contribution of acoustic features on perceived prominence was found to depend on the prominence pattern. If a dominantly prominent syllable is present in a given utterance, f0 and intensity contribute most to the perceived prominence, while duration contributes most when no syllable is dominantly prominent.

Single prosodic phrase sentences

A series of production and perception experiments investigating the prosody and well-formedness of special sentences, called Wide Focus Partial Fronting (WFPF), which consist of only one prosodic phrase and a unique initial accented argument, are reported on here. The results help us to decide between different models of German prosody. The absence of pitch height difference on the accent of the sentence speaks in favor of a relative model of prosody, in which accents are scaled relative to each other, and against models in which pitch accents are scaled in an absolute way. The results also speak for a model in which syntax, but not information structure, influences the prosodic phrasing. Finally, perception experiments show that the prosodic structure of sentences with a marked word order needs to be presented for grammaticality judgments. Presentation of written material only is not enough, and falsifies the results

Beat gestures influence which speech sounds you hear

Beat gestures - spontaneously produced biphasic movements of the hand - are among the most frequently encountered co-speech gestures in human communication. They are closely temporally aligned to the prosodic characteristics of the speech signal, typically occurring on lexically stressed syllables. Despite their prevalence across speakers of the world's languages, how beat gestures impact spoken word recognition is unclear. Can these simple 'flicks of the hand' influence speech perception? Across six experiments, we demonstrate that beat gestures influence the explicit and implicit perception of lexical stress (e.g., distinguishing OBject from obJECT), and in turn, can influence what vowels listeners hear. Thus, we provide converging evidence for a manual McGurk effect: even the simplest 'flicks of the hands' influence which speech sounds we hear
