An audio signal processing apparatus ( 1 ) comprises an audio input ( 3 ) for an entered audio signal, an audio output ( 5 ) for outputting an outgoing audio signal, and a processor ( 9 ) for performing a transformation ( 2 ) to improve the intelligibility of speech present in the entered audio signal. The transformation ( 2 ) transforms the entered audio signal into the outgoing audio signal, by modeling at least one aspect of the Lombard effect, based upon a noise level value ( 7 ). The Lombard effect is a specific way in which people change their speech, when speaking in noisy environments. The audio signal processing apparatus can be applied in a television receiver and a radio program receiver.
