Transcoding steganography (TranSteg) is a fairly new IP telephony steganographic method that functions by compressing overt (voice) data to make space for the steganogram by means of transcoding. [] Key Method A novel steganalysis method based on Gaussian mixture models and mel-frequency cepstral coefficients was developed and tested for various overt/covert codec pairs in a single warden scenario with double transcoding. The proposed method allowed for efficient detection of some codec pairs (e.g., G.711/G…
On the undetectability of transcoding steganography
A wide analysis of different steganalysis methods is performed to assess the possibility of TranSteg detection and identify the most 'undetectable' pairs of voice codecs.
Detecting Steganography of Adaptive Multirate Speech with Unknown Embedding Rate
The experimental results demonstrate that all the three steganalysis schemes are feasible and effective for detecting the existing steganographic methods with unknown embedding rates in AMR speech streams, while the DST-based scheme outperforms the others overall.

The improved version of a steganographic algorithm for IP telephony based on approximating the F0 parameter, which is responsible for conveying information about the pitch of the speech signal, yielded a significantly lower decrease in speech quality, when compared with the original version of HideF0.

Recent research results of steganography and steganalysis based on protocol and voice payload are classified and summarized and the paper also summarizes their characteristics, advantages, and disadvantages.
A Model for the Effective Steganalysis of VoIP
This work proposes an effective steganalysis method which considers the speech behavior as well as network protocol structure to detect hidden communication in voice over IP (VoIP).
Pitch and Fourier magnitude based steganography for hiding 2.4 kbps MELP bitstream
This work has dealt with the challenge of embedding a secret speech into a cover speech coded by a very low bit rate speech coder while maintaining a reasonable level of speech quality and was able to create hidden channels with maximum steganographic bandwidths up to 266.64 bit/s.

Audio steganalysis using deep belief networks
A new steganalysis method that uses a deep belief network (DBN) as a classifier for audio files and shows that it gives higher classification rates than the two other Steganalysis methods based on SVMs and GMMs.
Steganalysis of Adaptive Multi-Rate Speech Based on Extreme Gradient Boosting
A novel AMR steganalysis model is presented, which utilizes extreme gradient boosting (XGBoost) as the classifier, instead of support vector machines (SVM) adopted in the previous schemes, which can facilitate the excavation of potential information from the high-dimensional features and can avoid overfitting.

The paper presents a new steganographic method for IP telephony called TranSteg (Transcoding Steganography), which aims to find a codec that will result in a similar voice quality but smaller voice payload size than the originally selected.
Mel-cepstrum-based steganalysis for VoIP steganography
This paper introduces a Mel-cepstrum based analysis known from speaker and speech recognition to perform a detection of embedded hidden messages and shows how general forensic approaches can detect information hiding techniques in the field of hidden communication as well as for DRM applications.

By considering the codecs which are currently most popular for IP telephony, this paper aims to find out which codecs should be chosen for transcoding to minimize the negative influence on voice quality while maximizing the obtained steganographic bandwidth.
