System and method for speaker role determination and scrubbing identifying information

A computer-implemented method, comprising:

• generating a text-based representation of audio data from a file;
• identifying, from within the text-based representation, first text that includes one or more of at least one key phrase of a set of key phrases, at least one word that corresponds to a symbol character, or a predetermined length of numerical characters;
• determining a contextual correspondence between the first text and second text that is associated with identifying information, in the text-based representation, for removal therefrom, the second text comprising at least one non-numeric character therein;
• and
• replacing a segment of the audio data, corresponding to an identified portion of the second text, with different audio data.

A computer-readable storage medium having program instructions recorded thereon that, when executed by a processing device, perform a method for scrubbing identifying information from audio and textual data, the method comprising:

• generating a text-based representation of audio data from a file;
• identifying, from within the text-based representation, first text that includes one or more of at least one key phrase of a set of key phrases, at least one word that corresponds to a symbol character, or a predetermined length of numerical characters;
• determining a contextual correspondence between the first text and second text that is associated with the identifying information, in the text-based representation, for removal therefrom, the second text comprising at least one non-numeric character therein;
• and
• replacing a segment of the audio data, corresponding to an identified portion of the second text, with different audio data.
