"METHOD, SPEAKER ENCODER, INFRASTRUCTURE ELEMENT, AND SUBSCRIBER UNIT CONFIGURED TO QUANTIZE INFORMATION ABOUT A SPEAKER PARAMETER; AS WELL AS METHOD AND SPEAKER ENCODER CONFIGURED TO QUANTIZE FAMILY PARAMETER INFORMATION" A method and apparatus for predictively quantizing speech with speech includes a parameter generator and a quantizer. The parameter generator is configured to extract parameters from predictive speech frames such as speech with speech and to transform the extracted information to a frequency domain representation. The quantizer is set to subtract a weighted sum of the parameters for previous frames from the parameter for the current frame. The quantizer is set to quantize the difference value. A prototype puller can be added to first extract a prototype pitch period (tone or pitch) to be processed by the parameter generator.
