“…In the same direction, but analysing delexicalised, nonprofessional speech, Barbosa and Silva [6] showed that listeners discriminate read from narrated speech in Brazilian Portuguese based on speech rate, stressed syllable rate and pausing. Thus, temporal parameters play a crucial role for discriminating at least these two styles, as confirmed by a follow-up study [7].…”

“…For acoustic and perceptual analyses, at least three excerpts from 10 to 20 seconds were selected from each recording producing 517 excerpts for acoustic analysis (a subset of which was selected for perceptual evaluation). According to previous studies [6,9] which assessed speaking style differences in both Portuguese and French using sound pairs in a discrimination test, the 10-to-20 second duration provides a good inter-rater reliability, meeting two edge conditions: to have enough material for evaluating the prosodic structure of an utterance, on the one hand, and not to exceed the limits of the working memory [10], on the other hand.…”

This work investigates acoustic and perceptual differences in four language varieties by using a corpus of professional and non-professional speaking styles. The professional stimuli are composed of excerpts of broadcast news and political discourses from six subjects in each case. The non-professional stimuli are made up of recordings of 10 subjects who read a long story and narrated it subsequently. All this material was obtained in four language varieties: Brazilian and European Portuguese, standard French and German. The corpus is balanced for gender. Eight melodic and intensity parameters were automatically obtained from excerpts of 10 to 20 seconds. We showed that 6 out of 8 parameters partially distinguish professional from non-professional style in the four language varieties. Classification and discrimination tests carried out with 12 Brazilian listeners using delexicalised speech showed that these subjects are able to distinguish professional style from non-professional style with about 2/3 of hits irrespective of language. In comparison, an automatic classification using an LDA model performed better in classifying non-professional (96 %) against professional styles, but not in classifying professional (42 %) against non-professional styles.

ResumoAnalisamos um conjunto particular de parâmetros prosódicos para caracterizar sete variedades do Português Brasileiro (PB). As amostras de fala de 35 indivíduos do sexo masculino, com idade média de 35,4 anos, de São Paulo, Minas Gerais, Rio de Janeiro, Paraná, Distrito Federal (DF), região Nordeste (NE) e região Norte (N) foram coletadas. As amostras foram segmentadas em unidades de vogal-a-vogal (unidades VV) e oito medidas foram extraídas: taxa de elocução, média, desvio padrão, assimetria de zscore suave de duração da unidade VV, taxa de proeminência, taxa de não-proeminente da unidade VV/s, ênfase espectral e mediana de F0. One-Way ANOVA (p <0,05) indicou significado para a taxa de não-proeminente da unidade VV, o desvio padrão, a assimetria de z-score, a ênfase espectral e a mediana de F0. Os resultados separaram variedades faladas no Norte daquelas no Sul. A descrição das características prosódicas é relevante para fins forenses, já que pode ser usado como prova e apoio durante a resolução do caso.Palavras-Chave: Fonética Forense; Dialetos; Prosódia. AbstractWe analyzed a particular set of prosodic parameters in order to characterize seven Brazilian Portuguese (BP) varieties. Speech samples from 35 male subjects, mean age of 35.4 years, from São Paulo, Minas Gerais, Rio de Janeiro, Paraná, Distrito Federal (DF), Northeast region (NE) and North region (N) were collected. The samples were segmented into Vowel-to-vowel units (VV units) and eight measures were extracted: speech rate, mean, standard deviation and skewness of smooth z-score of VV unit duration, prominence rate, rate of non-prominent VV unit/s, spectral emphasis and median of F0. One-Way ANOVA (p<0.05) has indicated significance for rate of non-prominent VV unit/s, standard deviation and skewness of z-score, spectral emphasis and median of F0. The findings separated varieties spoken in the North from those spoken in the South. The description of prosodic characteristics is relevant for forensic purposes since it can be used as evidence and support during case resolution.
