Intonation correlates of canonical and non-canonical wh-in-situ questions in Spanish

This project investigates the intonation of canonical (information-seeking) and non-canonical wh-in-situ echo questions conveying repetition and surprise in Northern Peninsular Spanish. Data from 14 female participants were collected via a contextualised elicitation task. The following correlates were examined: (i) the melodic curve of the wh-in-situ question, (ii) the nuclear peak (in Hz), (iii) the wh-tonal range (i.e. the difference between the lowest nuclear Low and the highest boundary High), and (iv) the nuclear contour. Results show that all wh-in-situ questions investigated display similar melodic curves and nuclear contours, but canonical questions have significantly lower nuclear peaks and wh-tonal ranges than non-canonical questions. Echo-repetition and echo-surprise questions also differ in nuclear peak and wh-tonal range. We propose a tentative analysis, whereby canonical in-situ questions have a final H% boundary tone, in contrast to non-canonical questions, which have an extra-High (upstepped) final boundary tone (¡H%).
