Contemporary research into spoken language employs a wide range of approaches, from instrumental measures to perceptual and neurocognitive measures, to computational models, for investigating the properties and principles of speech in communicative settings across the world’s languages. 'Phonetica' is an international interdisciplinary forum for phonetic science that covers all aspects of the subject matter, from phonetic and phonological descriptions of segments and prosodies to speech physiology, articulation, acoustics, perception, acquisition, and phonetic variation and change. 'Phonetica' thus provides a platform for a comprehensive understanding of speaker-hearer interaction across languages and dialects, and of learning contexts throughout the lifespan. Papers published in this journal report expert original work that deals both with theoretical issues and with new empirical data, as well as with innovative methods and applications that will help to advance the field.
