Impacto de la implementación de Speech Ace mediante el enfoque CALL como herramienta para mejorar la pronunciación de las vocales como parte de la habilidad oral en estudiantes de quinto grado que aprenden inglés como segundo idioma en la escuela Jos

This study investigates how the integration of the Speech Ace platform and the Computer-Assisted Language Learning (CALL) approach can improve the pronunciation of vowels in English and the oral communication skills of fifth-grade students at José Joaquín Mora Porras School, who have faced learning challenges due to interruptions caused by the COVID-19 pandemic. Through the implementation of digital tools, the study aims to increase student participation and confidence when speaking English as a second language, supporting their progress in pronunciation and fluency through more frequent oral practice and the development of effective communication skills. In line with the bilingual objectives of the Costa Rican Ministry of Public Education, the research emphasizes the value of technological resources in promoting a dynamic, student-centered learning environment. The results indicate a notable improvement in vowel pronunciation and an increase in students' confidence when interacting in English, contributing to the formation of confident and competent speakers in a globalized context.
