| Abstract(in English) | With rapid spread of cellular phone and VoIP services, speech communication through mobile networks and the Internet is highly demanded. In this paper, we will propose a speech transcoding technique to convert the speech codes encoded with one system into that of the other system. We realized bi-directional speech transcoding between ITU-T G.729 and 3GPP AMR (7.95 kbps mode). Subjective evaluation tests show that our transcoder outperforms a conventional method in speech quality. We also indicate that the transcoder reduces delay time to half of the conventional method. |
