17. A device for embedding a watermark in an electronic audio signal, the device comprising: means for classifying the audio signal according to audio type; the classifying including means for processing the audio signal to detect a voiced and an unvoiced sound; means for selecting based on the audio type an audio perceptual model adapted for a detected voiced or unvoiced sound and insertion method; and means for embedding a watermark of an audio watermark type in the audio signal according to the selected perceptual model.
