Abstract :
The paper focuses on crypto security for data hiding in electroacoustic speech signals, and an example of data hiding in a speech signal based on segment fundamental frequency modification is described. In the process of embedding of data into speech artificial distortions can be perceivable for human ear. The author sets a task to determine acceptable limits of modification to maintain optimal security level and natural speech communication.
