Abstract
The proposed study considers the translation between speech vocoders of both wave form and parametric types. Transcoding and tandem methods of translation are proposed for the various codec pairs. The special case of multi-user conferencing scenarious with a variety of different codecs is considered. A methodology for the translation between different speech compression methods is developed. This methodology is used in the development and implementation of a parametric codec to parametric codectranslation.The minimization of degredation to the speech communication is considered with special emphasis placed on intelligibility. At the same time an effort is made to minimize the complexity of the translation. Specific subjective test methodologies are proposed to evaluate the degredation. The implementations are modeled and their complexities are measured.
