The relationship between intercultural communicative competence (ICC) and the speaking ability of language learners has been a focal point in foreign language education. This study aimed to investigate the relationship between ICC and speaking ability as demonstrated by Iranian EFL learners in an online Advanced Communication course, as well as their perceptions of how it impacted their language learning needs and objectives. The research utilized an explanatory mixed-method approach, incorporating both qualitative and quantitative methodologies for gathering and analyzing data. The testing group consisted of 154 undergraduate English language translation students, encompassing both male and female. Participants selected through convenience sampling. Data collection involved a homogeneity test, a speaking test evaluated by two raters, an ICC questionnaire, and a semi-structured interview. By employing Pearson Correlation and thematic analysis to analyze the data, the study unveiled a significant relationship between ICC and speaking ability, demonstrating potential benefits for both language learners and educators aiming to enhance linguistic and cultural speaking proficiency.
