Abstract:
A process of sending packets of real-time information comprising:A.) receiving audible speech; B.) converting the audible speech into digital information representing the audible speech, including analyzing the speech in plural frames of 10 milliseconds each, with each frame including two sub-frames of 5 milliseconds each, the converting including forming digital information of Linear Prediction Coding data, Longterm Prediction lag data, parity check data, fixed codebook ata, and adaptive and fixed codebook gain data from the speech; C.) first transmitting on a packet information system a first packet of digital data for a first frame of speech, the first transmitting including placing in the first packet first data for the first frame, the first data being the Linear Prediction coding data, the Longterm Prediction lag data, the parity check data, the fixed codebook pulse data for every other fixed codebook pulse, and the adaptive and fixed codebook gain data; and D.) second transmitting on the packet information system a second packet of digital data for the first frame of speech, the second transmitting including placing in the second packet second data for the first frame, the second data being the Linear Prediction coding data, the Longterm Prediction lag data, the parity check data, the fixed codebook pulse data for the remaining fixed codebook pulses not represented in the first packet, and the adaptive and fixed codebook gain data.
