  • Influence of Speech Codecs Selection on Transcoding Steganography
    Influence of Speech Codecs Selection on Transcoding Steganography Artur Janicki, Wojciech Mazurczyk, Krzysztof Szczypiorski Warsaw University of Technology, Institute of Telecommunications Warsaw, Poland, 00-665, Nowowiejska 15/19 Abstract. The typical approach to steganography is to compress the covert data in order to limit its size, which is reasonable in the context of a limited steganographic bandwidth. TranSteg (Trancoding Steganography) is a new IP telephony steganographic method that was recently proposed that offers high steganographic bandwidth while retaining good voice quality. In TranSteg, compression of the overt data is used to make space for the steganogram. In this paper we focus on analyzing the influence of the selection of speech codecs on hidden transmission performance, that is, which codecs would be the most advantageous ones for TranSteg. Therefore, by considering the codecs which are currently most popular for IP telephony we aim to find out which codecs should be chosen for transcoding to minimize the negative influence on voice quality while maximizing the obtained steganographic bandwidth. Key words: IP telephony, network steganography, TranSteg, information hiding, speech coding 1. Introduction Steganography is an ancient art that encompasses various information hiding techniques, whose aim is to embed a secret message (steganogram) into a carrier of this message. Steganographic methods are aimed at hiding the very existence of the communication, and therefore any third-party observers should remain unaware of the presence of the steganographic exchange. Steganographic carriers have evolved throughout the ages and are related to the evolution of the methods of communication between people. Thus, it is not surprising that currently telecommunication networks are a natural target for steganography.

  • Essential Technology for High-Compression Speech Coding Takehiro Moriya
    Information LSP (Line Spectrum Pair): Essential Technology for High-compression Speech Coding Takehiro Moriya Abstract Line Spectrum Pair (LSP) technology was accepted as an IEEE (Institute of Electrical and Electronics Engineers) Milestone in 204. LSP, invented by Dr. Fumitada Itakura at NTT in 975, is an efficient method for representing speech spectra, namely, the shape of the vocal tract. A speech synthesis large-scale integration chip based on LSP was fabricated in 980. Since the 990s, LSP has been adopted in many speech coding standards as an essential component, and it is still used worldwide in almost all cellular phones and Internet protocol phones.

  • The Sound of Silence: How Traditional and Deep Learning Based Voice Activity Detection Influences Speech Quality Monitoring
    The sound of silence: how traditional and deep learning based voice activity detection influences speech quality monitoring Rahul Jaiswal, Andrew Hines School of Computer Science, University College Dublin, Ireland [email protected], [email protected] Abstract. Real-time speech quality assessment is important for VoIP applications such as Google Hangouts, Microsoft Skype, and Apple Face- Time. Conventionally, subjective listening tests are used to quantify speech quality but are impractical for real-time monitoring scenarios. Objective speech quality assessment metrics can predict human judge- ment of perceived speech quality. Originally designed for narrow-band telephony applications, ITU-T P.563 is a single-ended or non-intrusive speech quality assessment that predicts speech quality without access to a reference signal. This paper investigates the suitability of P.563 in Voice over Internet Protocol (VoIP) scenarios and specifically the influ- ence of silences on the predicted speech quality. The performance of P.563 was evaluated using TCD-VoIP dataset, containing speech with degra- dations commonly experienced with VoIP. The predictive capability of P.563 was established by comparing with subjective listening test results. The effect of pre-processing the signal to remove silences using Voice Activity Detection (VAD) was evaluated for five acoustic feature-based VAD algorithms: energy, energy and spectral centroid, Mahalanobis dis- tance, weighted energy, weighted spectral centroid and four Deep learning model-based VAD algorithms: Deep Neural Network, Boosted Deep Neu- ral Network, Long Short-Term Memory and Adaptive context attention model. Analysis shows P.563 prediction accuracy improves for different speech conditions of VoIP when the silences were removed by a VAD.

  • Efficient Voice Activity Detection Algorithms Using Long-Term Speech
    Speech Communication 42 (2004) 271–287 www.elsevier.com/locate/specom Efficient voice activity detection algorithms using long-term speech information Javier Ramırez *, Jose C. Segura 1, Carmen Benıtez, Angel de la Torre, Antonio Rubio 2 Dpto. Electronica y Tecnologıa de Computadores, Universidad de Granada, Campus Universitario Fuentenueva, 18071 Granada, Spain Received 5 May 2003; received in revised form 8 October 2003; accepted 8 October 2003 Abstract Currently, there are technology barriers inhibiting speech processing systems working under extreme noisy condi- tions. The emerging applications of speech technology, especially in the fields of wireless communications, digital hearing aids or speech recognition, are examples of such systems and often require a noise reduction technique operating in combination with a precise voice activity detector (VAD). This paper presents a new VAD algorithm for improving speech detection robustness in noisy environments and the performance of speech recognition systems. The algorithm measures the long-term spectral divergence (LTSD) between speech and noise and formulates the speech/ non-speech decision rule by comparing the long-term spectral envelope to the average noise spectrum, thus yielding a high discriminating decision rule and minimizing the average number of decision errors. The decision threshold is adapted to the measured noise energy while a controlled hang-over is activated only when the observed signal-to-noise ratio is low. It is shown by conducting an analysis of the speech/non-speech LTSD distributions that using long-term information about speech signals is beneficial for VAD. The proposed algorithm is compared to the most commonly used VADs in the field, in terms of speech/non-speech discrimination and in terms of recognition performance when the VAD is used for an automatic speech recognition system.
