Abstract

This paper presents fundamental frequency and frequency perturbation measure (jitter) data collected for one infant over a 23-week longitudinal study. It examines whether there are changes in the fundamental frequency over time, whether they are linked to laryngeal constriction and if there is evidence of instability of the fundamental frequency. Results suggest that changes are apparent in both the fundamental frequency's mean and standard deviation over the course of the study. In addition the percent jitter also fluctuates over time. However the role of laryngeal constriction in these changes is still not fully resolved.
