| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper describes the outline and the subjective quality of a super-wideband speech coding, which we have developed for high quality VoIP (Voice over Internet Protocol) services over a high speed radio communication. It operates at the sampling rate of 22.05 kHz and more, and the bit rate of 48k - 64kbit/s, and offers equivalent subjective quality to the international standard codings ITU-T G.722.1 Annex C and MPEG-4 AAC-LD (Advanced Audio Coding - Low Delay). It provides users with much more comfortable listening environment and more presence than conventional narrowband speech codings. These features can realize such applications as conference call, remote education, and always-online call. | |
