Abstract
This paper presents a new single channel noise reduction method for suppressing periodic alarm noise in telephony speech. The presence of background alarm noise can significantly detract from the intelligibility of telephony speech received by emergency services, in particular, by the fire brigade control rooms. The attraction of the proposed approach is that it targets the alarm noise without affecting the speech signal. This is achieved through discriminating the alarm noise by appropriately modelling the contaminated speech. The effectiveness of this method is confirmed experimentally using a set of real speech data collected by the Kent Fire Brigade HQ (UK).
