System for giving intelligibility feedback to a speaker (1), speaking for an audience (2), comprising a first microphone (3) at the speaker's side and a second microphone (4) at the audience's side. Both microphones are connected to processing means (5) which are arranged to compute an intelligibility value based on both microphones' signals. Signalling means (6), preferably at the side of the audience, are arranged to generate an intelligibility feedback signal depending on the calculated intelligibility value. The signalling means being arranged to generate said intelligibility feedback signal in an optical form, visible for the speaker concerned. Wireless connection means (19) may interconnect the microphones, the processing means and the signalling means.
