Speech pause detection for noise spectrum estimation by tracking power envelope dynamics.

Speech pause detection for noise spectrum estimation by tracking power envelope dynamics.

A speech pause detection algorithm is an important and sensitive part of most single-microphone noise reduction schemes for enhancement of speech signals corrupted by additive noise as an estimate of the background noise is usually determined when speech is absent. An algorithm is proposed which det...
