A method and apparatus for reducing the undesirable characteristics of spectral estimation of a noise signal during speech signal generation (Mtthod amp; Apparatus For Reducing An Undesirable Characteristic Of A Spectral Estimate Of A Noise Signal Between Occurrence Of Voice Signals)
An improved method and apparatus for reducing the undesirable characteristics of the spectral estimation of the noise signal (203) during the generation of the speech signal (202) in the input signal (117). The spectrum of the input signal 117 is evaluated for spectral estimation 119 of the undesired characteristic-containing input signal 117 of the noise signal 203. The spectrum of the input signal 117 is substantially equal to the second bandwidth f3-f4, which is substantially greater than the first bandwidth f3-f4, over the first bandwidth f3-f4 during the speech signal 202 generation and during the speech signal 202, And smoothed over the bandwidth f2-f5. Also, the spectral estimation 119 of the input signal 117 is filtered during the speech signal 202 generation. The validity of the magnitude and / or phase component of the polls 301-305, which also represent the spectral estimation 119 of the input signal 117 during the generation of the speech signal 202, 0.0 120 /RTI
