This paper is concerned with the contributions of signal-driven and expectation-driven mechanisms to a general understanding of the phenomenon of prosodic prominence from a cross-linguistic perspective. It serves as an introduction to the concept of prosodic prominence and discusses the eight papers in the Special Issue, which cover a genetically diverse range of languages. These include Djambarrpuyŋu (an Australian Pama-Nyungan language), Samoan (an Austronesian Malayo-Polynesian language), the Indo-European languages English (Germanic), French (Romance), and Russian (Slavic), Korean (Koreanic), Medumba (Bantu), and two Sino-Tibetan languages, Mandarin and Taiwanese Southern Min.
Keywords: Expectation-based; Intonation; Prosodic typology; Signal-based.
