Noise suppression in speech signals |
摘要 |
During speech processing a filter adjusts a spectral envelope of an input speech signal with a frequency dependent adjustment factor. The adjustment factors for respective spectral components are selected dependent on the input speech signal. The factor is set to a first or second non-zero value, the second value being smaller than the first value, when a strength average for the spectral component is above and below a threshold value respectively. |
