Prosody and fluency of Finland Swedish as a second language: Investigating global parameters for automated speaking assessment

2023

This study investigates prosody and fluency of Finland Swedish as a second language (L2). The main objective is to investigate global measures of prosody and fluency as predictors of overall oral proficiency, fluency, and pronunciation ratings. We analyzed parameters related to temporal fluency, timing (based on syllable durations), and f0 change from spontaneous speech produced by 30 native and 235 non-native speakers of Finland Swedish representing proficiency levels from beginner to intermediate. We used pairwise comparisons to investigate the differences between native speech (L1) and L2 samples from different proficiency levels. To study the predictability of ratings with acoustic para…

The role of pause location in perceived fluency and proficiency in L2 Finnish

2022

Fluency is a commonly used descriptor of second language (L2) speaking skills. Unplanned and too frequent pauses, hesitations, and repetitions disrupt the flow of speech and can cause temporal irregularities at all levels of speech hierarchy, from syllable rate to phrasing. However, most studies that attempt to quantify fluency disregard pause locations. The current study investigates, whether and which pause locations affect the perceived fluency and proficiency in L2 Finnish. Several pause parameters were computed from spontaneous L2 Finnish speech samples. Pause locations were investigated with regards to clauses and phrases as well as incomplete words. The effect of pause locations to h…

Developing Automated Feedback on Spoken Performance : Exploring the Functioning of Five Analytic Rating Scales Using Many-facet Rasch Measurement

2022

In this study, we used the Many-facet Rasch measurement (MFRM) to explore the quality of ratings as well as the functioning of five analytic rating scales developed for automated assessment of L2 speech. This study is part of a multidisciplinary research project that develops automatic speech recognition (ASR), automated scoring and automated feedback for L2 Finnish and Swedish. The data include the analytic ratings (task completion, fluency, pronunciation, range, accuracy) gathered from human raters (n=14) who assessed L2 Finnish learners’ (n=64) speech samples using Moodle. The four-facet Rasch analysis showed that the raters performed and the rating scales functioned well, although task …

Coherent conditional probabilities and proper scoring rules

2011

In this paper we study the relationship between the notion of coherence for conditional probability assessments on a family of conditional events and the notion of admissibility with respect to scoring rules. By extending a recent result given in literature for unconditional events, we prove, for any given strictly proper scoring rule s, the equivalence between the coherence of a conditional probability assessment and its admissibility with respect to s. In this paper we focus our analysis on the case of continuous bounded scoring rules. In this context a key role is also played by Bregman divergence and by a related theoretical aspect. Finally, we briefly illustrate a possible way of defin…

Co-parental Couples and New Families: A Study of the Primary Triad

2015

Abstract Starting from current areas of research in the field of developmental theories, the aim of this work is to analyse parent-child interactions within a primary triad and to consider co-parenting couple and their children as an interactive matrix. In particular, parent-child relationship could be observed trough new developmental units of observation and coding systems in the multiple scenarios of new families. The deepening of this study may promote an effective connection between research and educational support as well as clinical work with families and parental couples.

Evaluación y caracterización biomecánica de los trinquetes de pelota valenciana. (Biomechanical assessment and characterization of the Valencian ball…

2012

El trinquete es la instalacion de referencia en la practica de la pelota valenciana, donde se juegan las modalidades profesionales de escala i corda y raspall. Sin embargo, no existe una normativa ni procedimientos de ensayo especificos que permitan definir las caracteristicas mecanicas que deben reunir paredes y pavimento del trinquete, para que los jugadores tengan una practica segura y optimicen su rendimiento. El objetivo de este estudio fue analizar diferentes variables mecanicas en las instalaciones de juego, determinar los procedimientos de ensayo mas adecuados y, finalmente, proponer unos valores mecanicos que definan una instalacion de calidad. Los estudios se llevaron a cabo en 10…

NULLITÀ DI PROTEZIONE » E POTERI DEL GIUDICE TRA CORTE DI GIUSTIZIA E SEZIONI UNITE DELLA CORTE

2014

The “nullità di protezione” in the rulings of the European Court of Justice and in the recent judgments of the Joint Sections of the Italian Supreme Court The Italian legislator provides, as a consequence of the unfairness of a term in consumers contracts, the remedy of nullity, which can only occur to the advantage of the consumer, whereby the court has jurisdiction to declare the term void on its own motion. This is the concept of “protective nullity“ (nullità di protezione) adopted in article 36 of the Italian Consumer Code, and framed by the European Court of Justice. It remains unclear, in such a rule especially when read in the framework of Italian law, whether the court is entitled t…

Usability Assessment of a UML-Based Formal Modeling Method Using a Cognitive Dimensions Framework

2008

Conceptual models communicate the important aspects of a problem domain to stakeholders. The quality of the models is highly dependent on the usability of the modeling method used. This paper presents a survey conducted on a method that integrates the use of a semiformal notation, namely the Unified Modeling Language (UML) and a formal notation, namely B. The survey assessed the usability of the method by using the grounded theory, the Cognitive Dimensions of Notations (CD) framework, and several criteria suggested by the International Organization for Standardization (ISO). Ten participants responded to the survey. The results suggest that the method is accessible to users when the princip…
