This paper examines the emotional dimensions of second language acquisition, highlighting how learners experience frustration and triumph throughout their language learning journey. The research explores the application of Emotion AI technologies to monitor and support learner affective states during language practice. It investigates the role of AI chatbots as tools for developing conversational abilities and intercultural pragmatic competence. The study addresses both the benefits of AI-powered language partners, such as responsiveness and non-judgmental interaction, and their limitations including emotional voidness and cultural biases. This work contributes to the growing intersection of artificial intelligence and language education, demonstrating how language models can be leveraged to create more supportive and culturally-aware learning environments.
