Exploring the discriminatory potential of F0 distribution parameters in traditional forensic speaker recognition

Kinoshita, Yuko; Ishihara, Shunichi; Rose, Philip


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]
