Method of retaining a media stream without its private audio content
First Claim
1. A method for processing audio content in an audio stream that includes private information, comprising:
- receiving the audio stream, at a data-processing system, the audio stream including a first speech waveform produced by a first party on a call, and 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 by analyzing the audio content of a segment of the second speech waveform against a model that describes the private information, wherein the model is represented by acoustic signatures in which non-prose-related characteristics of speech are stored; 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 processing private audio content in an audio stream, comprising:
-
receiving the audio stream, at a data-processing system, the audio stream including a first speech waveform produced by a first party on a call, and 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 by analyzing the audio content of a segment of the second speech waveform against a model that describes private information, wherein the model is represented by acoustic signatures in which non-prose-related characteristics of speech are stored; and retaining 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 processing private audio content in an audio stream, comprising:
-
receiving the audio stream, at a data-processing system, the audio stream including a first speech waveform produced by a first party on a call, and a second speech waveform produced by a second party on the call; creating a model describing the private audio content by generating an acoustic signature of the audio stream, in which at least one non-prose-related characteristic of speech is stored and 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)
