The term lip synchronisation applies to synchronising audio with the movement of a person's lips. If the data is out of synchronisation then human perception tends to identify the presentation as artificial, strange and annoying. We propose metrics to evaluate the degree of synchronisation for interactive multimedia communications. Through experimental results we demonstrate that such metrics are quite useful in providing quality of service (QoS) feedback to end users. A quantitative evaluation of the degree of synchronisation between loosely coupled multimedia tools is performed based on mean absolute deviation calculations and a subjective evaluation.
