Currenteducational policies and secondary school curriculum designs relegate pronunciation to thebackground, devoting greater focus to other linguistic elements. In the globalized andtechnological context in which we are framed, AI has become a paradigm shift in the waypronunciation is taught. AI-powered pronunciation-oriented tools such as Speechace have beenproposed as innovative tools with great pedagogical potential, as they offer automatedfeedback, personalized practice, and new learning contexts. This dissertation critically analyzesthe integration and implementation of Speechace as a potentially valuable tool withpedagogical value in a Spanish secondary school and Bachillerato classroom to improvepronunciation of English as a second language (ESL). The proposal consists of four activitiescentered around improving learners’ pronunciation and aimed at a target audience of studentsin their 4th year of compulsory secondary education or their 1st year of Bachillerato with aB1+ level in English. Through an analysis of elements such as accessibility, the quality offeedback provided, and automation, light is shed on the promising nature of Speechace for itsproper implementation. Lastly, this dissertation defends a balanced incorporation oftechnology-enhanced methodology whose main aim is to improve phonological competence,thereby diminishing negative emotional responses towards pronunciation and overall,mastering English oral abilities.
