Abstract

The main objective of the chapter is to provide an overview of existing speech watermarking technology and to demonstrate the importance of speech processing concepts for the design and evaluation of watermarking algorithms. This chapter describes the factors to be considered while designing speech watermarking algorithms, including the choice of the domain and speech features for watermarking, watermarked signal fidelity, watermark robustness, data payload, security, and watermarking applications. The chapter presents several state-of-the-art robust and fragile speech watermarking algorithms and discusses their advantages and disadvantages.
