This book investigates how the emergence of English as a Lingua Franca (ELF) necessitates a shift in pedagogical approaches to teaching pronunciation. Robin Noel Walker, an experienced educator in the field of English language teaching, utilizes current sociolinguistic research to argue that traditional native-speaker models may be less relevant than features focused on international intelligibility. The text provides a framework for teachers to prioritize the 'Lingua Franca Core'—a specific set of phonological features essential for successful communication between non-native speakers.

Experts in applied linguistics identify this work as a foundational resource for instructors transitioning away from traditional native-speaker pronunciation models. Readers frequently note the practical utility of the included audio materials for classroom application.
