Background/Objectives: Women’s vocalization during labor can be highly influenced by the attitudes and practices of nurse midwives. This study analyzed the perspectives of nurse midwives regarding women’s vocalization in the first and second stages of labor (n = 16). Methods: Descriptive study using semi-structured interviews analyzed through lexical analysis with IraMuTeQ software. Data collection took place between February and April 2024. Results: The analysis revealed six thematic classes: “Attitude toward vocalization”, “Significance of women’s self-image”, “Resistance and acceptance of vocalization”, “Control and inhibition of vocalization”, “Advantages and disadvantages of vocalization”, and “Usefulness of vocalization in caregiving”. Conclusions: There are different attitudes among nurse midwives toward women’s vocalization, ranging from respect to paternalistic control. Practical implications include the urgent need for curricular modules on vocalization in midwifery training programs and the deconstruction of biases that silence women’s voices during childbirth.

Taking into account the growing increase in the political and social interest in childbirth, it is critical to identify and explore the instruments that allow and enhance its humanization today. The use of vocalization seems to be a powerful and empowering tool for a positive birthing experience when used by women in labour. A scoping review will be developed to map the evidence and knowledge about women’s vocalization in the first and second stages of labour using the Joanna Briggs Institute methodology. The search will be carried out on the Web of Science, EBSCOhost Research Platform (selecting Academic Search Complete, MedicLatina, Cinahl plus with full text, Medline with full text), Willey Online Library, PubMed and Scopus. The National Register of Theses and Dissertations and the Open Scientific Repository of Portugal will also be taken into account. Three reviewers will conduct data analysis, extraction and synthesis independently. The outcomes pretend to be a source for identifying the use of vocalization by women in labour, in order to guide further research on the subject. This study was prospectively registered with the Open Science Framework on the 21 May 2024, with registration number DOI 10.17605/OSF.IO/Z58F4.

Despite growing interest in humanized childbirth practices, there is still little qualitative research exploring women’s perspectives on vocalization during labor. The present study aims to analyze women’s experiences with the use of vocalization in the first and second stages of labor. A descriptive and exploratory qualitative study was conducted using semi-structured interviews with 16 women in the postpartum period between February and April 2024. Participants were recruited by convenience sampling, and data saturation was achieved when no new themes emerged from the interviews. Thematic analysis was performed using IRaMuTeQ (version 0.8 alpha 7) software. The textual corpus generated allowed classification into five thematic categories: Vocalization as an instinctive expression in natural childbirth; Functionality of vocalization during labor; Medicalized childbirth and natural childbirth; Fears during childbirth and their contributing factors; Typology of vocalization in labor. We conclude that many women reported that vocalization during labor is instinctive and functional, providing pain relief, but also serving as a means of communication, empowering women. Its expression can be strongly influenced by sociocultural, emotional, and contextual factors in each woman’s particular sphere. These findings, although limited to a specific population, suggest that healthcare professionals should consider vocalization as an individualized support tool, taking cultural differences into account.
