Robustness of Fundamental Frequency under Mobile Phone Codec for Estimating Likelihood Ratios in Forensic Voice Comparison

Vu, Anh; Ishihara, Shunichi


This preliminary study will investigate the robustness of fundamental frequency (F0) as a forensic voice comparison (FVC) feature in estimating likelihood ratios (LRs) with mobile phone speech. F0 is one of the most commonly used features in FVC with some studies indicating its robustness against environmental noise and communication transmission [1], while some other studies point out that F0 is prone to various intrinsic and extrinsic factors, including emotions, intoxication, stress, etc....[Show more]
