Claim Text:
1. A method for reverberation suppression in an audio device comprising: determining a first estimated reverberation component of a reverberant speech signal that is measured by at least one microphone of the audio device; generating a first de-reverberated output signal with a first reverberation suppression based on the reverberant speech signal and the first estimated reverberation component that is based on a first synthetic impulse response; generating a second improved reverberation component using the entire first de-reverberated output signal as an input of a second synthetic impulse response; and generating a second de-reverberated output signal with a second reverberation suppression based on the reverberant speech signal and the second improved reverberation component.
