A investigação da declamação suscita interesse por sua carga expressiva. O propósito deste trabalho é investigar, por meio de um experimento fonético, os efeitos impressivos causados nos ouvintes por declamações do Soneto da Fidelidade. Na análise perceptiva, foram avaliados 4 descritores semânticos (agradabilidade, impacto emocional, projeção e interpretação vocais) com base em uma escala Likert. Como estímulos para a avaliação dos ouvintes foram utilizadas gravações de 8 locutores. O teste foi aplicado a 38 juízes. A análise acústica compreendeu parâmetros extraídos automaticamente. Os resultados são confrontados por meio de análise estatística multidimensional e o impacto impressivo das declamações é discutido.

This paper introduces an experimental study on the role of breathing patterns and acoustic characteristics on the appraisal of emotional content in two speech styles. The corpus is a song lyrics, read and sung by six professional lyrical singers, three men and three women. Three breathing parameters (breath cycle duration, inhalation duration and inhalation amplitude), twelve acoustic parameters, related to fundamental frequency, intensity, spectral tilt and Long Term Analysis, and one semantic descriptor (emotional impact) were analyzed. Results showed stylistic, gender and individual differences. Reading mainly differentiated from singing in relation to the three breathing measures and six acoustic measures. The durations of the breath cycles and the inhalations were higher in singing than in reading and in men than in women. The amplitude of the inhalation was an important factor in separating reading and singing in terms of emotional impact.

... They showed that pleasantness was related to an expanded pharynx, which causes F0 lowering (see Camargo et al., 2019). In a follow-up study of the effects of the recitation of the poem "Soneto da Fidelidade" (Menegon et al., 2021), this time recited by eight non-professional speakers, pleasantness was moderately relevant as a subjective parameter and related to voice quality and the parameter of LTAS slope. These works on BP and EP suggest that melodic, temporal, and voice quality dimensions could explain subjective positive evaluations in both poetry (BP) and ordinary prose (EP). ...

... There are many approaches to the annotation of speech breathing in the literature, with most of them demanding considerable human judgement and labour. Some authors detect inhalation loci based on listening [5], and manual annotation of plethysmography is also possible [6]. Otherwise, there have been attempts to automatically identify the speech breathing time series: One proposal is to take the zero-crossings of the acceleration of the respiratory signal within an appropriate bandwidth (e.g., 0.05 Hz − 10 Hz) [7]. ...
