This volume contains articles based on the presentations given at the Nordic Prosody XII conference, which was held at the Norwegian University of Science and Technology (Trondheim, Norway) in August 2016. The contributors investigate various prosodic aspects, including intonation, rhythm, speaking rate, intensity, and breathing, using approaches ranging from phonetic and phonological analysis to speech technology methods. While most of the studies examine read speech, some of them explore the prosodics of spontaneous speech. The languages that receive most attention are Norwegian, Swedish and Icelandic as well as Estonian, Latgalian and Polish. In addition to the larger Nordic languages, several papers focus on regional languages spoken in these areas.
