Abstract (en)
[origin: EP0898441A2] The acoustic signal input method uses the loudspeaker (5) of the radio device for converting a received acoustic signal, e.g. a speech signal, into a corresponding electrical signal. This electrical signal is compared with a signal obtained from the signal fed to the signal input (15) of the loudspeaker, via an adaptive filter (20), thus reducing the effect of the loudspeaker signal on the entered acoustic signal.
