Speech in both first and additional languages involves the processes of conceptualization, formulation, and articulation. The difficulty Japanese native speakers experience when producing spoken English is thought to arise from the cognitive load associated with executing these processes in real time. In the present study, learners were instructed to prepare the conceptualization and formulation stages of speech in advance, and engaged in practice over several weeks to examine changes in their awareness of English speaking. The effectiveness of ICT use, such as AI translation and generative AI, during the preparatory phase was also clarified through a questionnaire. In the post‑instruction questionnaire (n = 14), all participants affirmed that the prepared speaking practice helped reduce their resistance to speaking English and contributed to improvement, and that ICT was widely used, particularly as support for formulation. These findings suggest that an approach integrating preparatory learning activities with ICT‑based support contributes to enhancing learners’ speaking awareness and expressive ability.
