Protecting speech files from being hacked is a vital issue. In this paper's research, a new and simple method of speech files cryptography will be introduced. The method will simplify the encryption and decryption functions by using a simple replacement operation. The method will provide a high level of security based on using two secret private keys: the image_key and the image position, these two keys will be used to generate an indices key, which will be used to apply speech sample replacements in the encryption and decryption phases. The introduced method will be efficiently used to encrypt-decrypt mono and stereo speeches. The method will be very flexible; the changes of the private keys will be an easy process, without the need to make any changes in the method algorithm. The proposed meth will be tested and implemented using various speech files, the obtained results will be used to prove the sensitivity quality, and efficiency of the proposed method.
