8. A method of enhancing intelligibility of speech reproduced by a mobile communication device from a speech signal (s(n)), said mobile communication device comprising a vibrator (22), the method comprising:
-
determining background noise in relation to said reproduced speech, generating a control signal dependent on said background noise, and applying said control signal to said vibrator (22) so as to selectively operate said vibrator (22) during speech reproduction dependent on the level of said background noise.
