This pilot study investigates the relationship between stress situations and speech fluency in virtual reality environments. It aims to analyze how different stress scenarios, classified into low-, medium-, and high-stress environments, can affect speech rate, increase syllable/word repetitions, and lead to hesitations in university students. Previous research has established connections between stress situations and speech fluency, highlighting that stress can negatively influence behavior, cognitive processes, and communicative performance across various contexts, including oral presentations. An experiment was conducted with 30 participants randomly divided into three groups. Each group was exposed to different virtual stress environments (low/medium/high) during simulated oral presentations. A virtual reality platform was created to establish controlled environments and monitor the participants’ fluency in real time. An Analysis of Variance (ANOVA) test revealed that participants in the low-stress virtual environment performed better, achieving higher word and syllable production. In contrast, the high-stress virtual environment demonstrated an increase in disfluencies and hesitations. Results emphasize the impact of stress situations on oral communication, advocating for the use of virtual reality technology as a means of preparing individuals for challenging speaking scenarios. This approach has the potential to enhance speech fluency as a result of targeted practice in stress-inducing environments; that is to say, alleviating anxiety and improving overall communicative efficacy.

The increasing use of Virtual Reality in education has demonstrated its potential to enhance student engagement and skill development. This study investigates the design and implementation of a VR platform aimed at helping university students improve their oral presentation skills, while also evaluating user satisfaction through structured surveys. A total of 40 university students from the Speech and Language Therapy program participated in this study, focusing on their interactions with a custom-built, realistic VR application inspired by the main auditorium of their university. The students faced various distraction scenarios that emulated real-life public speaking challenges. Cybersickness symptoms were continuously monitored throughout the sessions; no participants reported or exhibited symptoms requiring interruption of the VR exposure. The VR environment was constructed using Unity and featured adjustable audience sizes, ambient sound controls, and recording capabilities for presentations. The results demonstrated significant enhancements in oral presentation skills post-VR training. Participants exhibited significant improvements in speaking fluency and clarity of expression, as well as reduced anxiety, during the VR experience. Specifically, their fluency increased significantly, and their clarity ratings also improved substantially. Furthermore, behavioral indicators showed a marked decrease in anxiety levels. Participants reported that the immersive nature of the VR experience enhanced their enjoyment, contributing positively to the overall outcomes. The findings suggest that VR is an effective tool for enhancing oral presentation skills in university students, leading to improved confidence and performance in real-life situations.

Objetivo: Analizar la evidencia disponible sobre soluciones digitales orientadas a la gestión y la experiencia del paciente en unidades de quimioterapia ambulatoria, contrastando sus alcances con la propuesta del software LAWEN. Método: Revisión narrativa integradora de literatura científica, técnica y gris publicada entre 2000 y 2025, mediante búsquedas en bases de datos internacionales y herramientas de apoyo basadas en inteligencia artificial. El análisis se organizó según la gestión operativa, experiencia del paciente y factores de implementación. Resultados: Las soluciones digitales existentes abordan de manera fragmentada la optimización de flujos, la comunicación clínica o el seguimiento de síntomas, con limitaciones de interoperabilidad y adopción en sistemas públicos. Conclusión: LAWEN se perfila como una propuesta tecnológica pertinente al integrar gestión operativa en tiempo real con comunicación orientada al paciente y su acompañante, favoreciendo una atención oncológica más eficiente, humanizada y equitativa.
