| Abstract |
This disclosure is directed to techniques for condensed voice buffering, transmission and playback. The techniques may involve identification of encoded voice frames as either speech or a pause, and selective exclusion of a portion of the frames for storage, transmission or playback based on the identification. In this manner, the techniques are capable of condensing a series of encoded voice frames. When variable rate coding is employed, a pause frame may be identified, for example, based on a threshold comparison for the rate of the encoded frame. In some cases, the techniques may involve excluding only a portion of the identified frames from a consecutive sequence of the identified frames, thereby preserving a minimum number of the identified frames needed for intelligible conversation. |
