Abstract—The discrete cosine transform (DCT) has performance
close to Karhunen-Loeve Transform (K-L Transform). In this
paper, DCT is used for speech information hiding. Secret
information is embedded by changing the parameters in DCT
domain and extracted by statistical method at the receiving end.
