Abstract:
1. A device comprising: a network interface for coupling to a network; and one or more processors coupled with the network interface, in which the processors are adapted to: receive voice signals; group the voice signals into a plurality of serial data speech frames; analyze the voice signals of at least some of the data speech frames to classify each in one of a plurality of different types of speech; determine a comparative discardability for some of the data speech frames relative to others from the type of speech; encapsulate the data speech frames into data packets, at least some of the data packets including a comparative discardability code indicating the determined comparative discardability of the encapsulated data speech frames; and transmit the data packets through a packet switched network; wherein determining a comparative discardability for the classified serial data speech frames further includes comparing one of the data speech frames to adjacent frames and associating a different comparative discardability with the data speech frame when there are differences between the frame and the adjacent frames.
