Abstract (en)

[origin: DE10026904A1] The method involves calculating a weighting factor a taking account of the periodicity and the stationarity of the encoded speech signal. The stationarity is substantially a measure of speech activity, and/or a measure for the ratio of speech level to background noise level of the speech signal section being observed.
