Network Speech. System Implications of Packetized Speech

Abstract

This paper reports on the effects--examined in parametric fashion--on the overall voice quality, acceptability, and communicability of speech packetization and its transmission through a packet-switched network. Speech processed through a number of real-time simulation programs developed to create anticipated anomalies (glitches) in packet speech systems were evaluated by informal acceptability testing. Depending on system design parameters, test results indicate that packet-system speech quality varies from essentially perfect (no packet-related anomalies) to unusable. Guidelines are provided for an acceptable packetized speech communication system.
