Sonic Signatures is devoted to the representation of sound patterns and sound structures across a diverse range of typologically distinct languages with the overall aim of understanding the nature of linguistic data structures from a principled balance between representational economy and the interfaces of phonology with other domains, including acoustic and visual. The volume embraces data spanning from Nivkh vowel harmony to Maxakalí sign language, and from the representation of consonant clusters in adult Laurentian French and to those found in child Greek and child Brazilian Portuguese. The volume strives towards concrete commitments to the theoretical understanding of empirical territory both familiar but with a novel take (English stress) and novel but with immediate relevance (Hungarian suffix allomorphy). With authors contributing from five continents, the book offers a range of perspectives on the representation of sound patterns, while nonetheless retaining a tight focus on the core questions of which characteristics and signatures are specifically encoded for these patterns in the phonological component of the language faculty.
