The current study aimed to examine the use of an AI-driven conversational chatbot to develop EFL oral communication skills of first-year secondary school students and reduce their oral communication apprehension. The study adopted a quasi-experimental research design (one experimental group). The study group was thirty-three (n = 33) secondary-stage students. The study instruments were designed by the researcher, namely, an EFL oral communication skills checklist, a pre-post EEFL oral communication skills test, and a communication apprehension questionnaire. Data was statistically analyzed. Based on the study results, there is evidence that the use of the AI-driven conversational chatbot can develop EFL oral communication skills of first-year secondary school students and reduce their oral communication apprehension. The study recommends examining the use of advancements in AI-driven chatbots with EFL secondary school students, in particular, and EFL learners, in general.
