Figure 8.6 Example visualising the principle of conversation surface structure analysis, Step 1: Extraction of On-Off speech activity patterns of speech for each conversation partner by means of voice activity detection. The example shows a conversation between two persons over a communication link with delay. For that reason, each person perceives a different reality of the conversational flow. That effect is visible by the shift of the active speech segments indicated by the dashed lines.

Another approach beyond conversation analysis in terms of e.g. double-talk for assessing the impact of delay is to look at task effectiveness. The recently standardised ITU-T Rec. P.1312 (2016) provides a description of such an approach, focussing on multiparty situations. The basic idea is to measure how well test participants are able to solve a task over the delayed communication link compared to solving the task face-to-face. While this method was shown to be sensitive for delay, it was originally intended for spatial audio systems. More details on this topic are given in Section 8.7.2.
