Abstract
Official abstract text for this publication.
Methods and systems for extracting speech from such packet streams. The methods and systems analyze the encoded speech in a given packet stream, and automatically identify the actual speech coding scheme that was used to produce it. These techniques may be used, for example, in interception systems where the identity of the actual speech coding scheme is sometimes unavailable or inaccessible. For instance, the identity of the actual speech coding scheme may be sent in a separate signaling stream that is not intercepted. As another example, the identity of the actual speech coding scheme may be sent in the same packet stream as the encoded speech, but in encrypted form.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for speech decoding, comprising: accepting communication packets that carry encoded speech, which was encoded in accordance with a speech coding scheme whose identity is not accessibly identified in the communication packets, wherein accepting the communication packets comprises accepting with each packet a respective time stamp indicating a reception time of the packet; using a processor, processing the encoded speech so as to automatically…
