TL;DR: In this article, a system and method for processing of audio and speech signals is disclosed, which provide compatibility over a range of communication devices operating at different sampling frequencies and/or bit rates.
Patent
Low-complexity, low-delay, scalable and embedded speech and audio coding with adaptive frame loss concealment
TL;DR: In this paper, a scalable and low-complexity adaptive transform coding method for speech and general audio signals is presented. But the method is not suitable for the Internet Protocol (IP)-based multimedia communications.
PatentDOI
Linear Prediction Coefficient Generation During Frame Erasure or Packet Loss
TL;DR: In this paper, a speech coding system robust to frame erasure (or packet loss) is described, where vectors of an excitation signal are synthesized based on previously stored excitation signals generated during non-erased frames.
PatentDOI
Parametric speech codec for representing synthetic speech in the presence of background noise
TL;DR: In this paper, a pitch and voice dependent spectral estimation algorithm (voicing algorithm) was proposed to accurately represent voiced speech, unvoiced speech, and mixed speech in the presence of background noise and background noise with a single model.
Proceedings ArticleDOI
A high-fidelity speech and audio codec with low delay and low complexity
TL;DR: This paper presents a high-fidelity speech and audio codec operating at a sampling rate of 32 kHz and a bit rate of 64 kbit/s, designed primarily for real-time speech communication systems with high port densities.
