This volume focuses on research on prosodic variation, comprising intonation, prosodic phrasing, and segmental phenomena that are prosodically motivated or constrained, in several languages and language varieties. Besides Portuguese (European, Brazilian, and African varieties), the book covers another three unrelated languages and their varieties: Romanian, Arabic, and Assamese (spoken in India and Bangladesh). Language coverage is thus diverse, including understudied languages/varieties. The approaches followed are both experimental and theoretical. All the chapters share a common goal: to add to the knowledge of prosodic variation in each of the languages and varieties studied, and to contribute to the understanding of prosodic grammar, in general.
