Pronunciation Instruction and Second Language Acquisition

Pronunciation instruction occupies a pivotal role within second language acquisition, intertwining perceptual training with articulatory practice to foster intelligible and fluent speech. Historically, teaching methods have ranged from mechanical drill in the audiolingual era to the more communicative approaches that emphasise meaning and interaction. Contemporary frameworks recognise pronunciation as a dynamic interplay of segmental features (individual vowels and consonants) and suprasegmental elements (stress, rhythm and intonation). Research underscores that effective instruction balances explicit corrective feedback with opportunities for naturalistic exposure, engaging learners in both focused phonetic practice and meaningful communicative tasks. The advent of speech technologies and digital tools has further transformed pedagogical possibilities, offering automated feedback and tailored training regimens. Moreover, individual differences in auditory processing and aptitude have emerged as crucial predictors of pronunciation outcomes, suggesting that adaptive, profile-matched instruction can optimise learning trajectories. Beyond classroom walls, improved pronunciation supports global communication, enhances learner confidence and mitigates misunderstandings in international contexts. As second language communities grow ever more diverse, the strategic integration of empirical insights into teaching practice remains vital for advancing both theory and pedagogical efficacy.

Automatic Speech Recognition (ASR): Technology that converts spoken language into text and provides feedback on pronunciation accuracy.

Comprehensibility: The ease with which a listener can understand spoken language, regardless of accent.

Nativelikeness: The degree to which a non-native speaker’s pronunciation approximates that of native speakers.

Auditory Precision: The ability to perceive and discriminate fine-grained acoustic details in speech input.
