Method of Retaining a Media Stream without Its Private Audio Content
First Claim
1. A method for omitting private audio content from an audio stream, comprising:
- receiving the audio stream, at a data-processing system, the audio stream conveying i) a first speech waveform produced by a first party on a call, and ii) a second speech waveform produced by a second party on the call;
determining whether a first segment of the first speech waveform comprises private information, based the content of i) a second segment of the first speech waveform that precedes the first segment, or ii) a predetermined segment of the second speech waveform; and
tagging the first segment when the first segment is determined to comprise private information.

Abstract
A method is disclosed that enables the handling of audio streams for segments in the audio that might contain private information, in a way that is more straightforward than in some techniques in the prior art. The data-processing system of the illustrative embodiment receives a media stream that comprises an audio stream, possibly in addition to other types of media such as video. The audio stream comprises audio content, some of which can be private in nature. Once it receives the data, the data-processing system then analyzes the audio stream for private audio content by using one or more techniques that involve looking for private information as well as non-private information. As a result of the analysis, the data-processing system omits the private audio content from the resulting stream that contains the processed audio.

12. A method for omitting private audio content from an audio stream, comprising:
-
receiving the audio stream, at a data-processing system, the audio stream conveying i) a first speech waveform produced by a first party on a call, and ii) a second speech waveform produced by a second party on the call; determining whether a first segment or a second segment of the first speech waveform comprises non-private information; and retain only the first segment when the first segment, but not the second segment, is determined to comprise non-private information. - View Dependent Claims (13, 14, 15)

16. A method for omitting private audio content from an audio stream, comprising:
-
receiving the audio stream, at a data-processing system, the audio stream conveying i) a first speech waveform produced by a first party on a call, and ii) a second speech waveform produced by a second party on the call; generating an acoustic signature of the audio stream, in which intelligible prose has been omitted from the acoustic signature; and retaining the acoustic signature as a representation of the audio stream. - View Dependent Claims (17, 18, 19, 20)
