This activity covers the creation and testing of “Lingua Guide,” an AI language-learning assistant that supports learning through clear explanations, guided practice, and curated public resources. The accompanying beginner Spanish guide outlines foundational steps—alphabet, core pronunciation rules, accent marks, motivation, and short daily practice—drawing on sources such as Duolingo and a Cambridge phonetics reference. It culminates in practical drills on vowel sounds and essential greetings with meanings and pronunciation.
