EVS (Enhanced Voice Services) is a multi-mode codec proposed by 3GPP (3rd Generation Partnership Project) for 4G mobile services with a good performance and codec quality. The key technology of EVS lies in the flexible switch between speech and audio

This paper describes a double-ended quality assessment system for speech with a bandwidth of up to 14 kHz (so-called super-wideband speech). The quality assessment system is based on a combination of local and global features, where the local feature

Postfilters are commonly used in speech coding for the attenuation of quantization noise. In the presence of acoustic background noise or distortion due to tandeming operations, the postfilter parameters are not adjusted and the performance is, there

Audio coding of harmonic signals is a challenging task for conventional MDCT coding schemes. In this paper we introduce a novel algorithm for improved transform coding of harmonic audio. The algorithm does not deploy the conventional scheme of splitt

This paper describes the time-domain bandwidth extension (TBE) framework employed to code wideband and super-wideband speech in the newly standardized 3GPP EVS codec. The TBE algorithm uses a nonlinear harmonic modeling technique that incorporates pr

This paper describes a novel audio coding algorithm that is a building block in the recently standardized 3GPP EVS codec [1]. The presented scheme operates in the Modified Discrete Cosine Transform (MDCT) domain and deploys a Split-PVQ pulse coding q

Kalman filtering is a powerful technique for the estimation of a signal observed in noise that can be used to enhance speech observed in the presence of acoustic background noise. In a speech communication system, the speech signal is typically buffe

In this chapter, we provide an overview of methods for speech quality assessment. First, we define the term speech quality and outline in Sect. 5.1 the main causes of degradation of speech quality. Then, we discuss subjective test methods for quality

The Kalman recursion is a powerful technique for reconstruction of the speech signal observed in additive background noise. In contrast to Wiener filtering and spectral subtraction schemes, the Kalman algorithm can be easily implemented in both causa
