- Substantial knowledge is available on the association of the indoor school environment and its effect among schoolchildren. In the same context, the SINPHONIE (School indoor pollution and health: Observatory network in Europe) conducted a study to collect data and determine the distribution of several indoor air pollutants (IAPs), physical and thermal parameters and their association with eye, skin, upper-, lower respiratory and systemic disorder symptoms during the previous three months. Finally, data from 115 schools in 54 European cities from 23 countries were collected and included 5175 schoolchildren using a harmonized and standardized protocol. The association between exposures and the health outcomes were examined using logistic regression models on the environmental stressors assessed in classroom while adjusting for several confounding factors; a VOC (volatile organic compound) score defined as the sum of the number of pollutants to which the children were highly exposed (concentration > median of the distribution) in classroom was also introduced to evaluate the mul tiexposu re - outcome association. Schoolchildren while adjusting for several confounding factors. Schoolchildren exposed to above or equal median concentration of PM2.5, benzene, limonene, ozone and radon were at significantly higher odds of suffering from upper, lower airways, eye and systemic disorders. Increased odds were also observed for any symptom (sick school syndrome) among schoolchildren exposed to concentrations of limonene and ozone above median values. Furthermore, the risks for upper and lower airways and systemic disorders significantly increased with the VOCs score. Results also showed that increased ventilation rate was significantly associated with decreased odds of suffering from eye and skin disorders whereas similar association was observed between temperature and upper airways symptoms. The present study provides evidence that exposure to IAPs in schools is associated with various health problems in children. Further investigations are needed to confirm our findings.

- Listeners rely on speech vocal cues to judge speakers’ age, size, personality, and other paralinguistic and extralinguistic features. These judgements are often based on vocal stereotypes which may be universally or culturally determined. This study examines how physical, psychological, social, and vocal features are perceived by listeners and which acoustic features may influence their judgements. An experiment integrating a perceptual test and acoustic measurements was performed. The corpus consisted of speech utterances produced by five animated film characters, dubbed in Brazilian Portuguese. The stimuli were judged by 77 Brazilian Portuguese native speakers, 46 women and 31 men, aged 20 to 50. The acoustic analysis was performed automatically. Acoustic measures included mean f0, f0 baseline, spectral emphasis and H1-H2. For inter-rater agreement analysis, Cronbach's Alpha was chosen. The results indicated close agreements among judges for all characters. Overall scores obtained for all characters were above .90. In interpreting the results, the influence sound symbolism codes may have on listeners’ judgments and the factors influencing vocal stereotypes have been considered. The discussion of the acoustic and perceptual analysis results takes into consideration if voice actors adapt their voices to fit the characters or otherwise are cast because of their natural voice characteristics

- This work comprises an experimental investigation approach of expressive speech that integrates methodological procedures of perceptual and acoustic analyses. As the object of this work, we have focused on voice quality and vocal dynamics. Speech samples from the four main personality-distinct characters in the animated feature film “Zootopia” dubbed by Brazilian voice actors have been analysed. Due to the expressive function of voice quality, we have posed the following question: what types of voice quality and vocal dynamics settings were used by the voice actors in the Brazilian dubbing of “Zootopia” to compose the vocal profiles of the characters? Perceptual evaluation of the 54 speech stimuli was performed using the Vocal Profile Analysis protocol (Laver & Mackenzie Beck, 2007). Acoustic measures were automatically extracted using the Expression Evaluator script (Barbosa, 2008) for PRAAT. The profiles for each of the four characters were composed based on the psychological traits described in the film script. The results of the acoustic analysis, the perceptual analysis of voice quality and vocal dynamics settings were correlated using the MFA (Multiple Factor Analysis) method in the R environment based on 40 variables (quantitative and qualitative) and it turned out that the speech stimuli were distributed in 6 clusters according to the variables analysed. The quantitative variables that presented the highest correlation percentage were: Standard Deviation of f0 Derivative, Standard Deviation of Spectral Tilt, f0 Median. The qualitative variables that presented the highest correlation percentage were: Lowered Larynx, Lip Rounding, Breathy Voice and Minimised Pitch Range. The research has presented evidence in favor of the symbolic use of phonic matter and contributions to the understanding of how vocal stereotypes are established.

- Our study examines the attribution of physical and psychosocial features to the characters of a dubbed animated film by comparing the results of a listening test experiment with the results of a reading test experiment. The aim of this study was to investigate the potential influence of lexical content on the perceptual evaluation of speaker characteristics. In the listening test, respondents were asked to listen to audio samples of dubbed dialogues in the film produced by voice actors and rate the characters on fourteen bipolar continuous scales. The task in the reading test was the same, except for the stimuli, which were transcriptions of the audio files. Results from both tests are congruent, as the character profiles based on the perception scores from each test are nearly identical for all characters. Differences are mainly due to the degree judgement scores are amplified by the characters' voice quality profiles.
