Abstract:
A method for speech processing includes determining a first unvoicing parameter for a first subframe of a speech signal, and determining a smoothed unvoicing parameter for the first subframe according to a second unvoicing parameter of a second subframe prior to the first subframe of the speech signal. The first unvoicing parameter is determined according to a periodicity parameter and a spectral tilt parameter. The method further includes computing a difference between the first unvoicing parameter for the first subframe and the smoothed unvoicing parameter for the first subframe and determining a classification of the first subframe using the computed difference as a decision parameter. The classification indicates whether the first subframe is an unvoiced speech signal or not an unvoiced speech signal. Bandwidth extension is performed on the speech signal for the first subframe according to the classification of the first subframe.

Claim (Index 6):
The method of  claim 5 ,\n wherein a weighting factor of the second unvoicing parameter for the second subframe is 0.9, and a weighting factor of the first unvoicing parameter for the first subframe is 0.1 when the second unvoicing parameter for the second subframe is greater than the first unvoicing parameter for the first subframe; and wherein the weighting factor of the second unvoicing parameter for the second subframe is 0.99, and the weighting factor of the first unvoicing parameter for the first subframe is 0.01 when the second unvoicing parameter for the second subframe is not greater than the first unvoicing parameter for the first subframe.
