Simulating Conversations for the Prediction of Speech Quality

by Thilo Michael

Overview

This book discusses the simulation of conversations through a novel approach of predicting speech quality based on the interactions of two simulated interlocutors. The author describes the setup of a simulation environment that is capable of simulating human dialogue on the speech level. The impact of delay and bursty packet loss on VoIP conversations is investigated and modeled for the use in the simulation. Based on parameters extracted from simulated conversations, the author proposes extensions to the E-model, a parametric model standardized by the International Telecommunications Union, in order to predict the quality of the simulated conversations. The author shows that predictions based on the simulated conversations outperform models that rely on the transmission parameters alone.

About the Author

Thilo Michael received his B.Sc. in Applied Computer Science at the Baden-Wuerttemberg Cooperative State University (DHBW) while working at IBM Germany. He obtained his M.Sc. in Computer Science at the Technische Universität Berlin, which focused on natural language processing and spoken dialogue systems. From 2017 on, he was employed at the Quality and Usability Lab at TU Berlin, where he finished his PhD on the simulation of conversations. As an invited speaker he held presentations on the topics of incremental spoken dialogue and chatbots.
