Objectives. The present work aims to contribute to the debate on the relationship between discrimination and production abilities in older pre-school-aged children and to fill a gap in the literature by providing evidence about this relationship in typically developing children speaking Italian, a language that is under-investigated. Methods. Tw...

It is known that communicative attitude (CA) tends to be more negative in children who stutter (CWS) compared to their non-stuttering peers since the preschool age and that a negative CA can be associated to other linguistic disorders. This study aims at investigating possible correlations among stuttering severity, communicative attitude, and spee...

A number of studies have shown that phonetic peculiarities, especially at the coarticulation level, exist in the disfluent as well as in the perceptively fluent speech of people who stutter (PWS). However, results from fluent speech are very disparate and not easily interpretable. Are the coarticulatory features observed in fluent speech of PWS a m...

The integrity of phonetic perception abilities is necessary for a normal functioning future speech development. Since the ability to discriminate linguistic sounds is typically associated to the correct acquisition and production of the same sounds, an alteration of this ability could contribute to the onset of speech and language disorders. Suppor...

Con ogni probabilità la situazione più frequente nel mondo odierno vede un bambino esposto nel corso dei suoi primissimi anni di vita a più di una lingua, come è sempre più frequente nel mondo di cultura inglese (Hambly et al., 2013) e anche in Italia (Galatà e Zmarich, 2011). Il bilinguismo è così stimolante anche dal punto di vista scientifico, c...

Introduction: The relationship between anxiety and stuttering has been widely studied. Previous researches conducted with children, adolescents and adults who stutter, have shown an increase of negative emotional reactions, as anxiety, to particular speech situations. The adults who stutter have manifested comorbidities with Social Anxiety Disorder...

The high morbidity of stuttering (just under 1% but up to 11% of cumulative incidence of stuttering by 4 years, Reilly et al., 2013), and the profoundly negative impact that can take on the school curriculum, the relational life and the professional career of a person, require adequate taking over by the state through its academic, welfare and rese...

From a phonological point of view, four glides (or approximants) exist in Italian: /j/, /w/, [i̯] and [u̯]. Glides still raise a lot of questions, from the definition of the necessary and sufficient features for their identification (Chitoran, Nevins, 2008), to their characterization at the acoustic and articulatory levels of speech production (Gic...

Few studies have addressed the ability of young children to produce stressed and unstressed syllables. Most of them focused on English speaking children and have adopted an acoustic analysis limited to the parameters of duration, intensity and F0. Even less investigated is the development of lexical stress in Italian children, and of the few studie...

Stuttering onset occurs for 95% of people who begin to stutter before the age of 4 years, tipically in the third year of life. Spontaneous recovery during y childhood is common, with recovery rates estimated at 68-96%, usually no later than the fourth year post-onset. If symptoms persist beyond this time, the efficacy of treatment might result more...

This paper analyses coarticulation in Italian and French monolingual stutterers tested in fluent speech. Our aim is to discover whether the stutterers' fluent speech presents specificities in intra-syllabic coarticulation opposed to the fluent speakers. Two factors will be considered: The role of the syllabic complexity and that of the language. Th...

In Italian, length contrast is exploited in the consonant system. Previous articulatory studies have focused on the temporal organization of gestures in Italian geminates and on the lower lip kinematics of the singleton/geminate distinction, and have showed that the time interval between the nuclei of two successive syllables does not depend on the...

Glides have been a challenging sound category from both a phonological and phonetic perspective and this is especially true for Italian. In this language four different glides can be distinguished based on their position in a syllable (pre or post-vowel), grouped together as either “semi-consonanti” (/j/ and /w/) or “semi-vocali” (/i/ and /u/). As...
