The expressiveness in the assessment of the voice professionals communication: a literature review

Abstract

ABSTRACT Purpose: to identify, through a critical review of the literature, what are the instruments used to assess the expressiveness of voice professionals and what are the parameters addressed in these instruments. Methods: a literature search was carried out on four platforms: Scopus, Science Direct, SAGE Journals and Medline. The search considered the period from 2006 to 2016 and original articles, theses, dissertations and specialization monographs were considered to compose the sample. Results: 5,295 productions were found in the four databases. Of these, after the filters by title of the production, evaluation of the summary, and content of the article, there were 39 articles with thematic expressiveness and voice professionals of which only seven presented some type of speech-language evaluation instrument that approached expressiveness. Conclusion: five studies presented their instruments in their entirety and of these, two were published in national journals, and none of them were validated. When the expressivity parameters are mentioned, those registered in greater numbers are those related to oral expressiveness. The parameters of nonverbal expressivity are still timid, with the predominant use of three variables, namely facial expression, gestures and posture.
