| Abstract(in English) | Digital watermarking for speech signals can effectively protect speech signals from malicious tampering. This paper proposes a tampering detection approach based on speech watermarking of modifications to line spectral frequencies (LSFs). Watermarks are embedded into LSFs that derived from linear prediction (LP) analysis with dither modulation-quantization index modulation (DM-QIM). We evaluated the proposed approach with inaudibility, robustness, and fragility. The results indicated that the proposed approach for tampering detection with minor modifications to LSFs not only enabled the watermarks to be inaudible but also achieved good balance between robustness against meaningful processing and fragility against tampering. |
