Abstract
The invention features a computer-implemented method for playing back an announcement message to a user device. The method includes initiating, by a computing device, an announcement session in response to a user device establishing communication with the computing device and determining, by the computing device, the announcement message to be played back to the user device. The method includes loading, by the computing device, into a queue associated with the announcement session, a descriptor referencing a memory buffer on the computing device. The memory buffer includes a plurality of memory partitions, each memory partition storing at least one portion of the announcement message encoded at a different rate. The method includes the computing device scheduling play back of the announcement message, playing the announcement message to the user device at a first rate and receiving a request from the user device for playback at a second rate.
