| Abstract: | This paper presents the 4 kbit/s speech coding candidate algorithm for the ITU T 4 kbit/s selection phase submitted by AT&T, Conexant, Deutsche Telekom, France Telecom, Matsushita, and NTT. The algorithm has been verified in independent subjective tests coordinated by ITU T and carried out in multiple languages. Subjective tests prove that this new algorithm is successful in improving the quality and meets a majority of the requirements in the extensive selection phase test. |
