Calculating gain for encoded speech transmission by dividing into signal sections and determining weighting factor from periodicity and stationarity |
摘要 |
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.
