The growing risk of privacy violation and espionage associated with the rapid spread of mobile communications renewed interest in the original concept of sending encrypted voice as audio signal over arbitrary voice channels. The usual methods used for encrypted data transmission over analog telephony turned out to be inadequate for modern vocal...

Increasing need for secure voice communication is leading to new ideas for securing voice transmission. This work relates to a relatively new concept of sending encrypted speech as pseudo-speech in audio domain over existing civilian voice communication infrastructure, like 2G-4G networks and VoIP. Such a setting is more universal compared to...

This paper details a novel distortion-tolerant speech encryption scheme for securing voice communications over digital voice-specific channels such as 3G/4G or VoIP voice calls. The scheme relies on the usual "loudness, pitch and timbre" parametric representation of speech signals but seen as points on various perceptually-continuous manifolds...

Motivated by an increasing need for privacy-preserving voice communications, we investigate here the original idea of sending encrypted data and speech in the form of pseudo-speech signals in the audio domain. Being less constrained than military "Crypto Phones" and allowing genuine public evaluation, this approach is quite promising for public...
