A novel and content based improved time spread echo hiding method (ITS) is presented. The system decoder relies upon distinguishing a watermarked bit based on a correlation amount quantity and also the echo kernel embeds the watermark bit into the whole signal. The presented system is cepstral content based in which the original signal cepstral portion of error at the decoder is removed and thus the performance of the decoder detection rate is improved considerably. Experimental results show the good results for the system robustness against the common signal processing attacks through calculating error detection rates in comparison with conventional echo hiding methods. Also good results were obtained for watermark inaudibility through mean opinion test (MOS) test and SNR value comparisons.
