Abstract
This preliminary study investigated the voice initiation period (VIP) and voice offset period (VOP) using high-speed digital imaging. The purpose of the study was to obtain preliminary data on VIP and VOP patterns of normal voice and to investigate the variability in VIP and VOP patterns in young female subjects within and between recording sessions. VIP was segmented into 3 phases: VIPa, VIPb, and VIPc. Results of the analysis of the data demonstrated that VOP is a more consistent measure than VIP and that VIPa is the most consistent phase of VIP. This study also suggested that changes in fundamental frequency and intensity may affect the number of glottic cycles necessary to complete VIP segments but not the VOP.
