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.
