Increased audio bandwidth introduces a significant leap in perceived quality of service compared to currently utilized narrowband telephony in second-generation mobile communications and the PSTN. IEEE Communications Magazine, May 2006 special issue on "Wideband speech coding standards and wireless services"

  6. Opportunities in voice: • Higher quality • Differential quality • Toll-free calling • …
