A subband excitation substitute based scheme for narrowband speech watermarking Article

Wei LIU, Ai-qun HU

Frontiers of Information Technology & Electronic Engineering 2017, Volume 18, Issue 5,   Pages 627-643 doi: 10.1631/FITEE.1601503

Abstract: forcing its power level to be the same as the original passband excitation of the cover speech, and a synthesisfilter is then used to spectrally shape the scaled watermark signal.At the extractor, a bandpass filter is first used to get rid of the out-of-band signal, and an analysisfilter is then employed to compensate for the distortion introduced by the synthesis filter.
