Abstract: In todayâ€™s internet world the data transmission should be fast and secured. The need for security in data communication is as long as mankind; since eavesdroppers often intercept such communication for malicious purposes. The secured signal may get hacked by breaking the password assigned to the system. Thus it is very important for designing a robust encrypted method for perfect data security. The objective of this project is to transmit an audio signal using digital image steganography technique to ensure security, integrity, robustness, ease of transmission. Audio file and cover image are encrypted using AES encryption algorithm. The encrypted file is converted into a stego file using steganography embedding algorithm. The encrypted and embedded audio file is de-embedded and decrypted at the receiver. The secret speech signal is obtained as it is at the receiver. While cryptography only encrypts the data, steganography ensures secured transmission of input by hiding the existence of data. Applications of steganography include government, military, banking, educational sectors, share market etc
