CALLIOPE is a conceptual multi-dimensional model that aims at approximating and categorizing the prosodic phenomena taking into account of all possible independent factors affecting the sound of so-called Information Units (IUs). In CALLIOPE, each IU is associated with a tuple composed of 12 labels, each belonging to a different dimension represent...

Speech analysis plays a pivotal role in the exploitation of forensic recordings in resolving a wide range of questions. Although this topic may include a large set of methodologies based on varied digital features (MFCC, Centroid, Harmonicity, VOT, etc., cf. [1]), this work approaches the theme from a phonetic perspective, taking into consideration...

The paper presents an artistic experience aimed at developing the vocal and emotional expressiveness of young people with intellectual, relational and physical disabilities. It follows the Esagramma® methodology, called Affective Vocal Education (EVA), and focuses on the production of a radio-drama based on the Roman de la Rose by Guillaume de Lorr...

What are speech data? The question is not as trivial as it may seem: every day both theoretical and applied linguistic research come up against problems deriving from bad data management. This topic is particularly thorny in interdisciplinary approaches such as the speech forensics analysis, whereby the recorded speech can be exploited as legal clu...

This research offers a preliminary survey on vowels and diphthong variation between two Irish English varieties: Galway (GW) and Letterkenny (LK). The results showed only a smaller difference between GW and LK with respect to the monophthongs, whereas a larger difference was found for the MOUTH diphthong. Despite the great amount of literature on E...

CALLIOPE is a conceptual multi-dimensional model that aims at approximating and categorising the prosodic phenomena. Its goal is to provide a method suitable for the analysis of dialogue and dialogic interaction, and the design of vo...

PESInet is an Automatic Prosody Recognition system aiming at classifying Information Units as Statement, Question or Exclamation. PESInet adopts a modular architecture, with a master NN evaluating the results of two independent BLSTM NNs that work on audio and its transcription. PESInet has been trained with our own three-class, balanced corpus com...

This work proposes a protocol for speech analysis disclosure methodologies to non-expert professionals. The final purpose is to transmit the potential of the scientific analysis in order to stem the multiple problems caused by misinformation. Italy and Cantone Ticino share the same official language but also similar needs. The main difference lies...
Article
The corrective focus is a particular kind of prosodic prominence where the speaker is intended to correct or to emphasize a concept. This work develops an Artificial Cognitive System (ACS) based on Recurrent Neural Networks that analyzes suitable features of the audio channel in order to automatically identify the Corrective Focus on speech signals...
Conference Paper
This study is a web-based, psychoacoustic test for adult, Italian native-speakers, investigating detection of different prosodic phenomena in Standard Italian utterances. The purpose was to investigate the influence of semantics on human ability to recognise different prosodic aspects, in order to understand the basic pieces of information involved...

The term prosody defines the group of audio paralinguistic and suprasegmental cues involved in the communicative and under- standing process of human speech. This paper presents our approach to automatic recognition of prosodic forms. In par- ticular, we present: CALLIOPE, a multi-dimensional and ab- stract model, aiming at categorising all prosodi...

This paper presents our approach to automatic recognition of prosodic forms. In particular, we present: CALLIOPE, a multi-dimensional model aiming at categorizing all prosodic forms; SI-CALLIOPE, a sub-space for which we defined a corpus of recorder prosodic forms; and the psychoacoustic experiment we are currently planning for investigating main a...

The purpose of this paper is to carry out a comparative survey on similarities and differences of the application of phonetics evidence in Brazilian1 and Italian2 courtrooms. Brazilian legal system is historically influenced by Roman Law whose principles keep being applied in contemporary democracies in Europe. Nevertheless, regarding the use of li...

This work investigates babblings during crises in Italian persons undergoing Court-of-Law examinations. The analysis was conducted on an audio/textual corpus that extends the one provided by the DIKE project. We found that most of crises (more than 80%) were characterized by babblings. Thus, we tried to characterize babblings looking at low-level a...

This work investigates crises in Italian Courts of Law examinations. Our hypothesis is that crises are correlated to a set of acoustic and psychological features that, therefore, could be leveraged to detect them. The analysis is based on the DIKE project (Sbattella Tedesco Trivilini, 2015). DIKE represents several aspects of examinations, accordin...

In this work we describe our roadmap to KaSPAR (Karaoke Speech-Prosody Analyzer and Recognizer), a software application dealing with the problematic of learning English as a foreign language, for Italian (or other transparent, romance languages) mother-tongue subjects with dyslexia. We aim at enriching the traditional learning-based methods, and le...
