Conferencing with Pitch-Excited Channel Vocoders
The use of digital vocoder systems presents many problems in the area of conferencing communications. Certain of these problems are discussed and possible solutions are suggested. Voice-excited vocoders have many advantages over pitch-excited vocoders from the standpoint of conferencing; however, the pitch-excited vocoder has the advantage of greater bandwidth savings. Effort spent in development of conferencing techniques for pitch-excited vocoders should be repaid many times by the savings obtained in bandwidth requirements. Thus this paper deals almost exclusively with the problems involved in conferencing with pitch-excited vocoders.
