Abstract

In this paper, six different conversation tasks with pre-determined content, referred as 'non-free conversations', are designed for evaluation of audiovisual delay. Extensive subjective experiments were performed to evaluate the delay perception. Experimental results show that subjective audiovisual quality is getting worse with the increase of delay, while delay perception is closely linked to the characteristics of audiovisual conversations. Using talkspurts to capture the temporal characteristics of non-free conversations, a logarithmic function or quadratic polynomial may be appropriate to model the perception delay.
