Abstract

A wireless communication apparatus includes a voice encoder and uplink suppression logic. The voice encoder may be configured to encode a number of digital audio samples into voice payload data using one or more audio compression algorithms. The uplink suppression logic may be configured to provide an indication such as a flag, for example, of whether or not the voice payload data is ready for further processing. In addition, the uplink suppression logic may also be configured to cause one or more bad speech frames to be transmitted in response to the indication that the voice payload-data is not ready for further processing. For example, a bad speech frame may include a voice data block including the voice payload data and EDC that does not match the voice payload data.
