Formantabhaengige speech enhancement

There is an arrangement for speech signal processing described. A received input microphone signal includes a voice signal component and a noise component. The microphone signal is converted into a frequency domain consisting of short-term spectral signals. The speech formant are in the spectral signals on the determination of regions of high energy density in the spectral signals is determined based. One or more dynamically adjusted gain factors for the spectral signals are used to improve the speech formant.
