Analysis and Demonstration of the Quantile Vocoder [PDF]
, 1986 A new scheme for speech compression is proposed, implemented and evaluated in this thesis. In this new scheme, the spectral envelope of the power spectral density of a speech frame is encoded using quartiles or order statistics.

Robust Speech Detection for Noisy Environments
, 2011 This paper presents a robust voice activity detector (VAD) based on hidden Markov models (HMM) to improve speech recognition systems in stationary and non-stationary noise environments: inside motor vehicles (like cars or planes) or inside buildings ...

Trends in Hearing, 2016 Multichannel amplitude compression is widely used in hearing aids. The preferred compression speed varies across individuals. Moore (2008) suggested that reduced sensitivity to temporal fine structure (TFS) may be associated with preference for slow ...

The effect of speech and audio compression on speech recognition performance [PDF]
2001 IEEE Fourth Workshop on Multimedia Signal Processing (Cat. No.01TH8564), 2002 This paper proposes an in-depth look at the influence of different speech and audio codecs on the performance of our continuous speech recognition engine. GSM full rate, G711, G723.1 and MPEG coders are investigated. It is shown that MPEG transcoding degrades the speech recognition performance for low bitrates whereas performance remains acceptable for

Glottal source estimation from coded telephone speech using a deep neural network [PDF]
, 2017 In speech analysis, the information about the glottal source is obtained from speech by using glottal inverse filtering (GIF). The accuracy of state-of-the-art GIF methods is sufficiently high when the input speech signal is of high-quality (i.e., with ...
