Mastering English phonetics and phonology is essential for teachers, translators, and interpreters who seek to ensure precision, clarity, and naturalness in oral communication. While phonetics focuses on the study of speech sounds — their articulation, transmission, and perception — phonology examines sound patterns and the way these sounds function within the linguistic system. For professionals who teach or interpret the English language, understanding aspects such as stress, intonation, connected speech, and the distinction between vowel and consonant sounds is crucial to avoiding misunderstandings, improving pronunciation, and capturing subtle nuances of meaning in spoken communication. This lecture proposes a reflection on how phonetic and phonological knowledge can become effective pedagogical tools in adult language education, contributing to the development of fluency, intelligibility, and communicative confidence in multilingual and multicultural contexts.
