Abstract:
A system for reducing degradation of analog voice data that must be encoded and decoded using a vocoder, comprising:(a) a sending device having a vocoder utilizing a first vocoder format to encode the analog voice data to digitized data; (b) a transliterator to transliterate the digitized data to transliterated data having a second vocoder format to reduce degradation to the digitized data caused by encoding and decoding during transmission of the digitized data from the sending device, wherein the second vocoder format is selected from a plurality of vocoder formats after the transliterator uses each of the plurality of vocoder formats to process the digitized data, analyzes the digitized data after the process, and determine that the second vocoder format results in the least amount of degradation in transmitting the digitized data; and (c) a receiving device for receiving the transliterated data from the sending device, the receiving device having a vocoder utilizing a third vocoder format to convert the transliterated data back to the analog voice data.
