Method and system for the treatment of audio signal representative data in a reception system

摘要

The device has a detector (34) detecting current digital data corresponding to interpolated data or non-interpolated data, in a received digital data flow. A detector (36) analyzes the current data to detect the data corresponding non-speech in case of the interpolated data, and scrambling units (38) scramble the current data based on a scrambling law e.g. frequency shifting. An output (42) sends the scrambled current data to an interactive voice response machine (3) via an internet protocol network, so as to be interpreted by the machine when the current data is not non-speech digital data. An independent claim is also included for a method for processing digital data representing audio signals in a reception system.
