The present study investigates the prosody of yes/no questions (in comparison with statements) in Chinese learners and native speakers of Italian. Acoustic analyses and a perceptual test were performed, in order to identify the main trends in non-native productions. Results show the relevance of prosody, which differentiates elementary, intermediate and advanced Chinese learners of Italian. Listening tests based on prosody transplantation also suggest that non-native segments with a native Italian prosody are rated as less accented than are native Italian segments with a non-native prosody. Similar trends were found, overall, in terms of question/assertion discrimination, confirming the relative importance of prosody. These findings could be helpful for teachers and learners of Italian as a foreign language.
Patients with Parkinson's disease (PD) usually reveal speech disorders and, among other symptoms, the alteration of speech rhythm. The purpose of this study is twofold: (1) to test the validity of two acoustic parameters—%V, vowel percentage and VtoV, the mean interval between two consecutive vowel onset points—for the identification of rhythm variation in early-stage PD speech and (2) to analyze the effect of PD on speech rhythm in two different speaking tasks: reading passage and monolog. A group of 20 patients with early-stage PD was involved in this study and compared with 20 age- and sex-matched healthy controls (HCs). The results of the acoustic analysis confirmed that %V is a useful cue for early-stage PD speech characterization, having significantly higher values in the production of patients with PD than the values in HC speech. A simple speaking task, such as the reading task, was found to be more effective than spontaneous speech in the detection of rhythmic variations.
The ancient Appia route was built across central‐southern Italy between the fourth and second century before the common era (B.C.E.). At the Aurunci Mountain Pass, the route crosses carbonate ridges that provided the raw material used to pave the road in the first century C.E. This material was replaced with lava blocks of unknown origin in the third century C.E. The study area is at least 50 km from the main volcanic centers along the peri‐Tyrrhenian side of Italy, such as the Colli Albani, Roccamonfina, and Middle Latin Valley volcanoes. The main objective of this research was the chemical–petrographic and isotopic characterization of rock samples from the Appia flagstones to unravel their possible provenance. The analytical procedure included scanning electron microscope and electron microprobe analyses and 87Sr/86Sr–143Nd/144Nd isotopic measurements. Samples taken from unknown quarries found in the Middle Latin Valley volcanic field underwent the same analyses. After comparing the analysis results with data from the literature, the most likely source area was identified with the Roccamonfina precaldera ultrapotassic sequence. The availability and use of volcanic resources for the construction and maintenance of the ancient Appia route in the investigated territories are only outlined in this work and deserve further study.
The high number of low-literate vulnerable refugees and asylum seekers among L2 Italian learners requires a rethinking not only of approaches and teaching methods, but also of assessment strategies. The present study aims to investigate the effectiveness of two different rating scales in the assessment of writing skills for this peculiar target of learners, a Standard Evaluation Scale and a Functional Adequacy Scale. Application of the two assessment methods on a corpus of about 450 written texts produced by 50 refugees and asylum seekers from 16 different countries, with an Italian A2 level competence, demonstrated that a Functional Adequacy Scale can be a more reliable and efficient tool than a Standard Evaluation Scale for valorising also poor writing skills, instead of underlying the limits of low-literate productions.
Parkinson’s Disease (PD) is a neurological illness which also has effects on speech production, resulting in segmental and suprasegmental abnormalities. The aim of the current study is to test the validity of two acoustic parameters - %V and VtoV - for the detection of rhythmical variation in early-stage PD speech, in comparison to healthy speech. 40 Italian native speakers were enrolled in the research, 20 early-stage PD subjects and 20 neurologically healthy and matched controls, and a corpus of read speech was collected. The results of voice analysis confirmed an alteration of vocalic duration and %V in PD productions. In particular, %V could be a reliable cue for PD speech characterization, even at the very early onset of the disease.
