Summary

Recommendation ITU-T P.836 provides a conversation simulation model which is able to simulate realistic conversational behaviour to produce conversations on the semantic level, as well as on the speech signal level. The simulation can replicate conversations with different interactivity patterns and the resulting simulated conversations will reflect changes in this conversation behaviour due to delayed transmission and packet loss. The simulated conversations may be used to predict conversational quality in combination with signal-based or parametric quality prediction models, such as the E-model, e.g., in drive-test scenarios.
