Abstract

The invention provides a voice encryption method and device, a voice decryption method and device, a model training method and device, and a voice communication method and device. The voice encryption method comprises steps of carrying out the fragmentation of voice data, and obtaining N voice fragments, N being an integer greater than 1; extracting a sound spectrum feature of each voice segment; inputting the sound spectrum feature of each voice segment into a pre-trained voice encryption neural network to obtain a voice encryption feature corresponding to each voice segment; and splicing the voice encryption features corresponding to the voice segments in sequence to obtain voice encryption data. Through the voice encryption method provided by the invention, security of voice data encryption can be improved.

Description

technical field [0001] The present invention relates to the technical field of speech, in particular to a method and device for speech encryption, speech decryption, model training, and speech communication. Background technique [0002] With the continuous development of communication technology, the cost of information transmission and storage is getting lower and lower, and voice has gradually become an important data medium. With the emphasis on data security, voice encryption is often required during voice transmission and storage. However, in the prior art, the voice is often encrypted based on the secret key. This encryption method usually has certain regularity and is easy to be cracked. In addition, this encryption method often involves the transmission of the secret key, which is easy to cause the secret key to be stolen. This leads to the leakage of encrypted voice. It can be seen that the existing key-based voice encryption method has the problem of low securit...
