Exploring the discriminatory potential of F0 distribution parameters in traditional forensic speaker recognition
Despite its many prima facie attractive properties for forensic speaker recognition, F0 is regarded as having limited forensic value due to its large within-speaker variability. However, its forensic use to date has been limited mostly to its long-term mean and standard deviation. This paper examines the discriminatory potential, within a Likeli-hood Ratio-based approach, of additional parametric features from the distribution of long-term Fo: its skew, kurtosis, modal F0 and modal density....[Show more]
