  • Variable rate speech data compression
    Patent number: 6952669
    Abstract: A device is presented that includes an encoder. The encoder compresses a plurality of signals at variable frame rates based on a plurality of prioritized parameters to reduce signal bandwidth while preserving perceptual signal quality. Also presented is a device that includes a decoder. The decoder decompresses a plurality of compressed signals at variable rates based on a plurality of prioritized parameters to reduce signal bandwidth while preserving perceptual signal quality.
