abstract = {In today’s Voice-over-IP (VoIP) telephony, packet loss is one of the most
prominent degradations. Severely bursty packet loss can lead to multiple consecutive
packets and thus important parts of the transmitted speech to be lost. In
listening-only tests, the understandability of packet loss-affected speech can be
modeled based on the available audio cues in the signal. However, in real conversation
scenarios, not every unintelligible word is important for the continuation
of the conversation. Thus, even utterances that are largely affected by packet loss
might not lead to a request of retransmission of the information (e.g., “Could you
please repeat that?”) and thus disruption of the conversation flow. lexical frequency
can be used as a tool to measure the importance of the information transmitted. In
this paper, we analyzed a set of 84 packet loss degraded telephone conversations
and investigated the ability of listeners to recover from missing words resulting
from the packet loss as a function of their frequency. We found that the request
for information retransmission appears more often for messages with less frequent
words.},
