Now, wideband speech transmission up to 7 kHz is being offered in a growing number of services. This yields a more pleasant sound, and even intelligibility advantages can be shown. But wideband transmission, coding, and general processing require new features to be taken into account. An auditory determination of the resulting speech quality follows the same lines as that for narrowband signals. The results, however, need a new interpretation, and instrumental quality measures rely even less on a saturated understanding than those for telephone-band speech.

Due to an overemphasis of higher frequencies in fricatives, as well as to added noise, which may itself have quite different characteristics in the wideband case (see Sec. 2). Instrumental Attribute Measurement Following the ideas outlined in Sec. 2 for narrowband assessment, measurements are searched for which now characterize the systems’ influences on the attributes distance (or directness), continuity (or short-time artifacts), lisping (or frequency content), and noisiness (or hissing sound and added noise).

The quality will, of course, suffer in the lower-rate options, but it is still felt to be considerably better than that of the narrowband ISDN transmission. 4 Wideband Speech Signals 19 Nevertheless, there used to be little enthusiasm for the offered “better sound at the same rate”. The interest in wideband-speech transmission did not grow until three other developments appeared: the availability of interfaces beyond the classical hand-set, like head-sets or hands-free terminals, varying-rate coding schemes for mobile phones, and the virtually unlimited data volumes possible in the Internet.
