Abstract: An enterprise voice system such as a contact centre is disclosed which provides a speech analytics capability. Whilst call recording is common in many contact centres, calls are normally recorded in single-channel audio files in order to save costs. Previous attempts to provide automatic diarization of those recorded calls have relied on training the system to recognise voiceprints of users of the system, and then comparing utterances within the recorded calls to those voiceprints in order to identify who was speaking at that time. In order to avoid the need to train the system to recognise voiceprints, an enterprise voice system is disclosed which inserts a digital watermark into the digitised audio signal from each user's microphone. By inserting the digital watermark with an energy, and, in some cases also with a spectrum, which matches the digitised audio signal, and taking advantage of typically only one user speaking at a time, a mark is left in the recorded call which a speech analytics system can use in order to identify who was speaking at different times in the conversation.

Abstract: A wireless access point (10) connected to a fixed telecommunications network (12) broadcasts codes relating to one or more network identities (100, 101) identifying availability of wireless connection to the access point, If connection to the telecommunications network (12) is lost, it suspends one of the identity codes (100) and replaces it with a special identity code for a network identity (102) configured to co-operate with a mobile terminal (53) equipped to recognise the special identity code and transmit a message over another communications link (6, 49) to alert a service centre (7) to the fault (13).
