The effect of network degradation on speech recognition
Gerhard R. Joubert, Etienne Barnard · 2005
We describe a system, based on open-source tools, that was developed in order to study the effect of network degenerations in Voice-over-Internet-Protocol applications on speech-recognition accuracy. Sophisticated play-out algorithms are found to enhance recognition accuracy when network jitter occurs, but do not generally compensate for packet loss successfully. We also confirm that packet loss is a more significant problem for larger loss burst-lengths. 1
