The influence of frame length on speaker identification performance
No full textSpeaker recognition/identification is a challenge for the implementation of security applications. Unfortunately, degradation in performance is usually observed for high pitched speakers and also whenever average pitch varies significantly between enrolment and testing. In this paper, a study on the impact of the frame length used to extract features from speech signal on the performance of speaker identification is presented. Tests have been carried out on a text-dependent database. Results show that a combination of different frame sizes between the training and the recognition phases can cope with the degradation. A reduction between 40% and 65% in false rejections has been generally observed. © 2007 IEEE
Speaker identification by multi-frame generative models
No full textIn this paper an approach called Multi-Frame Speaker Models (MFS) is proposed, in order to cope with performance degradation generally observed over (short and medium) time and trials in Speaker Identification's task. The approach, based on generative models, uses multiple frame's length for speech processing in training and testing phase. A complete multi-expert system is also presented which is able to implement the proposed approach on the whole set of speakers and to obtain a near optimum for the ER's reduction. © 2008 IEEE
Seeing or Not Seeing Your Conversational Partner: The Influence of Interaction Modality on Prosodic Entrainment
No full textIn speech entrainment research, a less investigated yet crucial aspect for modelling multimodal interactive dialogue systems is the influence of inter-action modality, i.e. whether conversational partners who are visible to each other would entrain their speech more with respect to when eye contact is inhibited, or not. In our study, we compared prosodic adaptation behaviour (convergence and synchrony) of the same speaker pairs involved in collaborative game sessions under two conditions: audiovisual vs audio-only interaction. Results provide a complex picture, with a tendency to vocal entrainment enhancement when the speech/audio channel is the only one available
Prosodic convergence in Italian game dialogues
No full textIn this study we explore the manifestation of prosodic convergence between pairs of Italian speakers involved in a non-competitive game. Results show evidence of prosodic convergence and/or divergence between partners, where prosodic parameters and coordination strategies involved can vary across dialogue pairs. Also, degree of asymmetry in prosodic convergerce appears to be related to speaker empathy
Il diritto penale nel canone di Mario Romano
No full textThis paper deals with the extension and the extraordinary scientific value of the works written by a great Master in Criminal Law, such as Mario Romano. The Author briefly presents some of the most relevant contributions given by Professor Mario Romano to the Criminal Science, first of all his "Commentario sistematico del codice penale" (Systematic Commentary on the penal code), a unique work. Finally, the paper talks about some topics which have been developed inside the work "Studi in onore di Mario Romano" (Studies in Honour of Mario Romano)
Measuring prosodic entrainment in Italian collaborative game-based dialogues
No full textIn a large number of studies, it has been observed that conversational partners tend to adapt each other’s speech over the course of the interaction. This phenomenon, variously named as entrainment, coordination, alignment or adaptation, is widely believed to be crucial to mutual understanding and suc-cessful communication in human interaction. Modelling human adaptation in speech behaviour would also be very important for improving naturalness in voiced-based human-machine interaction systems. Recently, a body of research in this field has been devoted to find evidence of prosodic entrainment by measuring a number of acoustic-prosodic parameters in some languages, yet not in Italian. Our study offers a contribution to this research line. We analysed game-based collaborative dialogues between Italian speakers, by measuring their articulation rate, pitch range, pitch level and loudness. Results show some evidence of overall speech coordination (convergence and synchrony) between conversational partners, wherein the combination of specific prosodic parame-ters involved may vary across dialogues. Our results are in line with those ob-tained in previous studies on other languages, thus contributing to providing a useful basis for modelling prosodic adaptation in multilingual spoken dialogue systems
Introduzione, a Mario Tobino, Il Clandestino
No full textL'introduzione presenta il libro più ambizioso di Mario Tobino, Il Clandestino, dedicato al racconto della sua esperienza con i gruppi clandestini della Resistenza Viareggina, libro con cui l'autore vinse il Premio Strega, nel 1962, imponendosi all'attenzione del grande pubblico dopo il successo dei libri manicomiali. Una nuova edizione in cui Paola Italia valorizza i materiali inediti dell'Archivio Tobino conservato presso l'Archivio Contemporaneo A. Bonsanti del Gabinetto GP Vieusseux di Firenze,Paola Italia presents an Introduction to the new edtion of Il Clandestino, the most ambitious of Mario Tobino's novels, dedicated to the story of his experience with the groups of the Tuscan Resistance when he was a psichiatric doctor ar Lucca. With this book the author won the Strega Prize, in 1962, attracting the attention of a wide public after the success of his psichiatric books.
