In this study, we examine acoustic features around boundaries of Intonation Units that have been perceptually segmented. An account of both sides of a boundary is the concept of analysis, i.e. acoustic features are measured at the end of one IU and at the beginning of the following IU. Since Hebrew is our target language, an account of the stress assignment on the prosodic word level was taken. Results show that duration and pitch characteristics at continuous boundaries are affected by the stress metrical structure.
