This paper examines the lexical tonal accent contrast in monosyllabic words in the Trondersk dialect of Norwegian. The results of a production experiment in which speakers produced the unmarked accent and the circumflex accent showed that the tonal distinction is characterized by a difference in f0 maximum, f0 height at onset, f0 minimum and its timing, and height of the final Accent Phrase H tone. The presence of the tonal accent contrast on monosyllabic words is unusual among dialects of Norwegian and Swedish.
