Abstract
A system controller ( ) is for transferring a low bit rate digital voice message. The system controller generates from an analog voice signal representing the voice message a set of speech model parameters, and generates a first derived set of speech model parameters from a first subset of the set of speech model parameters, the first derived set encoding the voice signal at a second voice quality and second vocoder rate that are less, respectively, than a first voice quality and vocoder rate. The system controller transmits ( ) the low bit rate-digital voice message comprising the first derived set of speech model parameters to a communication receiver ( ). The communication receiver requests ( ) an incremental message when the quality of the voice message is unsatisfactory. The system controller generates and transmits ( ) an incremental message-and the communication receiver uses ( ) the incremental message to generate a higher quality voice message.
