AB  - We present a noise-robust algorithm for estimating the active level ofspeech, which is the average speech power during intervals of speechactivity. The proposed algorithm uses the clean speech phase to removethe quadrature noise component from the short-time powerspectrum of the noisy speech, as well as SNR-dependent techniquesto improve the estimation. The pitch of voiced speech frames isdetermined using a noise-robust pitch tracker and the speech levelis estimated from the energy of the pitch harmonics using the harmonicsummation principle. At low noise levels, the resultant activespeech level estimate is combined with that from the standardizedITU-T P.56 algorithm to give a final composite estimate. The algorithmhas been evaluated using a range of noise signals and givesconsistently lower errors than previous methods and than the ITU-TP.56 algorithm, which is accurate for SNR levels of above 15 dB.
