The book introduces the current version of the American Movie Corpus (also known as the AMC),<br /> a structured dataset of authentic movie dialogs produced in the United States of America from 1959 to 2019.<br /> Starting from the assumption that spoken language has a primary role in communication,<br /> the main idea behind the work is to offer a tool for language learners/teachers to investigate and develop spoken lexico-grammatical competence,<br /> also in areas of specialized communication. Although movies are artifacts by nature, recent investigations have revealed that their dialogs<br /> share the same textuality and linguistic features which characterize face-to-face conversation and that language learners<br /> can improve their spoken competence by actively watching movies.
