This paper addresses the problem of single channel speech enhancement at very low signal-
to-noise ratios (SNRs)(< 10 dB). The proposed approach is based on the introduction of an …

DIGITAL SPEECH TRANSMISSION AND ENHANCEMENT Enables readers to understand
the latest developments in speech enhancement/transmission due to advances in …

This chapter is concerned with the application of modern signal processing techniques to
the restoration of degraded audio signals. Although attention is focussed on gramophone …

Karlheinz Brandenburg and Mark Kahrs With the advent of multimedia, digital signal
processing (DSP) of sound has emerged from the shadow of bandwidth limited speech …

In hands-free speech communication, the signal-to-noise ratio (SNR) is often poor, which
makes it difficult to have a relaxed conversation. By using noise suppression, the …

A novel speech enhancement technique is presented based on the definition of the
psychoacoustically derived quantity of audible noise spectrum and its subsequent …

This paper presents and compares algorithms for combined acoustic echo cancellation and
noise reduction for hands-free telephones. A structure is proposed, consisting of a …

With this comprehensive and accessible introduction to the field, you will gain all the skills
and knowledge needed to work with current and future audio, speech, and hearing …

The modern telecommunications field is concerned with freedom and, in this context, hands-
free systems offer subscribers the possibility of talking more naturally, without using a …

Speech signals are frequently disturbed by statistically independent additive noise signals.
When the power fluctuation of the noise signal is significantly slower than that of the speech …
