System and Method for Secure Processing of Speech Signals using Pseudo-speech Representations

A computer program product residing on a non-transitory computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:

• generating a transcript by processing a speech signal using an automated speech recognition (ASR) system;
• determining a plurality of confidence scores associated with a plurality of respective portions of the transcript;
• identifying a sensitive portion of the transcript based upon, at least in part, the plurality of confidence scores;
• generating a pseudo-speech representation of the sensitive portion;
• and
• generating a synthetic speech signal by processing the transcript and the pseudo-speech representation of the sensitive portion.
