| Title: | Performance Analysis of a Decoder-Based Time Scaling Algorithm for Variable Jitter Buffering of Speech over Packet Networks | ||
| Authors: | Philippe Gournay, Kyle D. Anderson, VoiceAge Corp., Canada | ||
| Abstract: | This paper describes how a CELP speech decoder such as the VMR-WB decoder can be modified in order to deliver decoded speech frames of variable length, a feature that is required for adaptive jitter buffering. This method is shown to be successful for playout delay adaptation in terms of both subjective quality and reactivity. Moreover, it requires almost no additional complexity provided some clever limitations are imposed on time scaling. | ||
