This work addresses the evaluation of the human and the automatic
speaker recognition performances under different channel
distortions caused by bandwidth limitation, codecs, and
electro-acoustic user interfaces, among other impairments. Its main
contribution is the demonstration of the benefits of communication
channels of extended bandwidth, together with an insight into how
speaker-specific characteristics of speech are preserved through
different transmissions. It provides sufficient motivation for
considering speaker recognition as a criterion for the migration
from narrowband to enhanced bandwidths, such as wideband and
super-wideband.
