ITRW on Experimental Linguistics
In this paper I describe four melodic patterns which can occur in the yes/no question, namely: i) the final rise pattern, typical of the unmarked polarity yes/no question, ii) the internal rise pattern, correlated with positive polarity questions, iii) the delayed rise pattern, indicating negative polarity, i.e. the speakers discordance with the sentence propositional content, and iv) the double rise pattern, found in rhetorical yes/no questions and requests. The relevance of phonological representation is discussed on the grounds of auditory tests with synthesized speech.
