| Tóm tắt: | Among the various speech and language technologies (such as automatic speech
recognition, speech synthesis, speaker recognition, language and accent recogni
tion, etc.), it can be easily said that ‘speech coding’ is the most successful, both in
terms of how well the underlying sciences of information theory, quantization,
source coding, channel coding, etc. apply to the real world signals, as well as in
terms of how well such an application of the different theories to realize actual
speech coding systems has led to their seamless and indispensable permeation into a
wide range of digital communication scenarios. This is easily borne by the fact that
speech coding is also the only speech technology that has reached a level of
practically deployable applicability, making it possible (and hence, requiring) to
be standardized, as reflected by a gamut of standards (such as prescribed by various
standards organizations such as ITU-T, ETSI, MPEG, INMARSAT, DoD, NATO,
TIA, etc.) in communications technologies spanning a wide range of operating
conditions, each marked by specific bit-rates and associated quality of the coded
speech, along with other speech coding operational parameters such as delay,
complexity, robustness, etc. [C95]. |
