F0 is considered to provide speaker-specific information in some extent. Based on the widely agreement that extrinsic F0 is helpful for speaker identity, this paper investigates the possibility of making use of both extrinsic and intrinsic features of Cantonese tone system as speaker-dependent characteristic. Considering the special characteristic of Cantonese tone system, relative tone ratios and F0 register are proposed to model the tone systems generated by different speakers. The investigation is carried out over both recognition and analysis. The results primarily show the potential of implementing such features on speaker characterization.
