Introduction: Many transgender individuals find their voice often not matching their gender identity. By using gender-affirming voice training, voice and communication specialists help transgender women find a voice that aligns with their gender identity. Short-term outcomes of voice training programs showed progress in listener perception, self-perception, and satisfaction of transgender women's voices.

Article Synopsis
  • Studies on unilateral vocal fold paralysis (UVFP) treatment often lack structured protocols, leading to this preliminary study assessing two therapies: water-resistance therapy (WRT) and vocal function exercises (VFE).
  • Ten participants with UVFP were split into two groups, undergoing intensive treatment while their voice quality, glottal closure, and patient perspectives were evaluated at multiple points in time.
  • Both WRT and VFE showed positive effects on voice quality and patient-reported outcomes, yet individual results varied significantly; further research with larger groups is needed for validation and improvement of these therapies.

Background: Although psychological factors have been implicated in patients with functional dysphonia (FD), conventional voice therapy (CVT) typically targets the aberrant voice symptoms exclusively. Yet, CVT is not always successful, and in view of the significant adverse quality of life impact combined with the financial burden on the healthcare system and society, research is needed to elucidate the underlying psychophysiology of FD and improve treatment outcomes.

Objectives: The first objective of this research project is to compare the occurrence and frequency of symptoms and/or disorders related to autonomic nervous system (ANS) dysfunction in patients with FD with gender- and age-matched vocally healthy controls, using a case-control study.

Objectives: One role of a speech-language pathologist (SLP) is to help transgender clients in developing a healthy, gender-congruent communication. Transgender women frequently approach SLPs to train their voices to sound more feminine, however, long-term acoustic effects of the training needs to be rigorously examined in effectiveness studies. The aim of this study was to investigate the long-term effects (follow-up 1: 3months and follow-up 2: 1year after last session) of gender-affirming voice training for transgender women, in terms of acoustic parameters.

Introduction: Due to the heterogeneity in language trajectories and differences in language exposure, a lot of bilingual children could use some extra support for the acquisition of the school language to reduce the risk of language problems and learning difficulties. Enhancing bilingual children's narrative abilities in the school language could be an efficient approach to advance the general school language abilities as well. Therefore, this study aimed to investigate whether a narrative intervention could improve both general and narrative school language abilities of typically developing bilingual (Turkish-Dutch) children.

Introduction: Providing an adapted language input in a multicultural classroom is often challenging to educators. Teachers are frequently the parents' first contacts for language counseling and educational support, and therefore, they may influence the language exposure not only in the classroom but at home as well. This study aimed to investigate the cognitive, emotional, and behavioral attitudes of teachers toward multilingualism in Flanders.

Purpose: Unilateral vocal fold paralysis (UVFP) is a neurological voice disorder that is often first treated by a speech-language pathologist (SLP). In literature, little consensus is found regarding voice therapy onset, duration, frequency, and content. The aim of the current study is to investigate the clinical practice of SLPs for treatment of UVFP regarding diagnostics and treatment characteristics.

Article Synopsis
  • The study explored the effectiveness of a new vocal exercise technique called the semi-occluded water resistance ventilation mask (SOVM-WR) for women with dysphonia, aiming to incorporate continuous speech into voice therapy.
  • A controlled trial with 20 participants showed no significant changes in objective vocal measures after the therapy, but there were notable improvements in patient-reported outcomes like vocal comfort and quality for both the new and control methods.
  • The results suggest that while SOVM-WR is comparable to traditional water resistance therapy, further research is needed to assess its long-term benefits and effectiveness in enhancing spontaneous speech communication.

Background: A promising way to obtain vocal economy and efficiency is by semi-occluding the vocal tract while phonating. Current knowledge about the immediate effects of semi-occluded vocal tract (SOVT) phonation on the laryngeal function and configuration is based mainly on computer modelling or excised larynges studies. In in vivo SOVT studies, electroglottography (EGG) has been the most commonly used laryngeal outcome, showing contradictory results between studies.

Background & Aims: Even though evidence for the use of linguistic-phonological intervention approaches in children with a cleft (lip and) palate (CP±L) is still limited, these approaches are being used by speech-language pathologists (SLPs) to treat active or compensatory cleft speech disorders in clinical practice. It is, however, unknown to what extent linguistic-phonological intervention is acceptable to SLPs. The aim of this study is to investigate the retrospective acceptability of linguistic-phonological intervention in children with a CP±L from the perspective of SLPs using the theoretical framework of acceptability (TFA).

Background And Aims: Individuals with speech disorders are often judged more negatively than peers without speech disorders. A limited number of studies examined the attitudes of adolescents toward peers with speech disorders due to a cleft lip with or without a cleft of the palate (CL ± P). Therefore, the aim of the present study was to investigate the attitudes of peers toward the speech of adolescents with CL ± P.

Purpose: Bilateral vocal fold paralysis (BVFP) is a severe disorder that can result in respiratory, swallowing, and voice-related problems. Most surgical treatments do not restore laryngeal function and often need to compromise voice quality to preserve respiratory function. Laryngeal reinnervation (LR) may offer a solution to this problem, but literature on longitudinal outcomes of this procedure is scarce.
