Abstract EN
There have been serious issues concerning the protection of speech signals from malicious tampering.
Digital watermarking has been paid much attention in solving this problem.
This paper proposes a tampering detection approach based on speech watermarking by modifying the line spectral frequencies (LSFs).
Watermarks are embedded into LSFs that derived from linear prediction (LP) analysis with dither modulation-quantization index modulation (DM-QIM).
Minor modifications to LSFs introduced by quantization not only enable the watermarks to be inaudible to human auditory system but also provide the possibility of robustness against meaningful processing and fragility against tampering.
We evaluated the proposed approach with objective evaluations with respect to inaudibility, robustness, and fragility.
The results indicated that the proposed approach for tampering detection not only satisfied inaudibility but also provided good robustness against meaningful processing and fragility against malicious tampering.
