Speech and music discrimination: Human detection of differences between music and speech based on rhythm

Rhythm in speech and singing forms one of its basic acoustic components. Therefore, it is interesting to investigate the capability of subjects to distinguish between speech and singing when only the rhythm remains as an acoustic cue. For this study we developed a method to eliminate all linguistic components but rhythm from the speech and singing signals. The study was conducted online and participants could listen to the stimuli via loudspeakers or headphones. The analysis of the survey shows that people are able to significantly discriminate between speech and singing after they have been altered. Furthermore, our results reveal specific features, which supported participants in their decision, such as differences in regularity and tempo between singing and speech samples. The hypothesis that music trained people perform more successfully on the task was not proved. The results of the study are important for the understanding of the structure of and differences between speech and singing, for the use in further studies and for future application in the field of speech recognition

Continuous Interaction with a Virtual Human

Attentive Speaking and Active Listening require that a Virtual Human be capable of simultaneous perception/interpretation and production of communicative behavior. A Virtual Human should be able to signal its attitude and attention while it is listening to its interaction partner, and be able to attend to its interaction partner while it is speaking – and modify its communicative behavior on-the-fly based on what it perceives from its partner. This report presents the results of a four week summer project that was part of eNTERFACE’10. The project resulted in progress on several aspects of continuous interaction such as scheduling and interrupting multimodal behavior, automatic classification of listener responses, generation of response eliciting behavior, and models for appropriate reactions to listener responses. A pilot user study was conducted with ten participants. In addition, the project yielded a number of deliverables that are released for public access

Prosody, polyphony and politeness: A polyphonic approach to prosodic configurations common to French and Spanish

From a theoretical perspective based on the Theory of Argumentation in Language (Théorie de l’Argumentation dans la Langue – TAL) and the Theory of Polyphony (Théorie de la Polyphonie Énonciative – TPE), the present study describes and analyses polyphonic configurations that are disclosed through the use of certain voice traits; configurations which, unmistakably common to both French and Spanish, are manifested by what is said and what is prosodically shown in utterances. Within a French corpus and a Spanish corpus of naturally occurring discourse, the patent polyphonic dimension of intonation has been explored in order to demonstrate that locutors’ utterances themselves reveal the orientation of enunciation through both the marking of the lexical and grammatical components and the prosody within which they are embedded. Through this study, the authors show how the locutor – the discursive character presented by the utterance as responsible for its enunciation – puts on stage a multiplicity of enunciators, or viewpoints, which allow him or her to protect the image of self, i.e., the locutor’s own image, and expose, protect or enhance that of others. Polyphony is materialized in two different ways: one in which the enunciator embodied in the prosody reinforces the locutor’s assimilation to the wording of the utterance and another in which the enunciator corresponding to the intonational feature does not match what is expressed through words.Fil: Garcia Negroni, Maria Marta.

Security, population and governmentality : UK counter-terrorism discourse (2007-2011)

Over the past decade, governments worldwide have taken initiatives both at a national and supra-national level in order to prevent terrorist attacks from militant groups. This paper analyses a corpus of policy documents which sets out the policy for UK national security. Informed by Foucault’s (2007) theory of governmentality, as well as critical discourse analysis and corpus linguistics, this paper analyses the ways in which the liberal state in late modernity realizes security as discursive practice. A corpus of 110 documents produced by the UK government relating to security in the wake of the 7/7 attacks between 2007 and 2011 was assembled. The paper analyses the discursive constitution of the Foucaultian themes of regulation, knowledge and population, though carrying out a qualitative analysis of relevant key wards, patterns of collocation, as well as features of connotation and semantic prosody
