Abstract: A method for anonymizing data includes receiving call data of a call in an interaction recording system located behind a firewall of an internal network sub-environment, and within the internal network sub-environment: (i) storing the call data including interaction metadata, (ii) generating a speech-to-text transcript corresponding to words spoken by one or more callers, and (iii) generating an anonymized transcript by anonymizing personally identifiable information. A computing system includes a processor, and a memory including computer executable instructions that, when executed by the one processor, cause the system to perform the method. A non-transitory computer readable medium contains program instructions that when executed, cause a computer system to perform the method.

Abstract: A confidential sentiment analysis method includes receiving call data, storing the call data including interaction metadata, generating a speech-to-text transcript corresponding to words spoken by one or more callers, generating an anonymized transcript by anonymizing personally identifiable words, and generating a sentiment score by analyzing the anonymized transcript. A computing system includes a processor, and a memory including computer executable instructions that, when executed by the one processor, cause the system to receive call data, store the call data, generate a speech-to-text transcript, generate an anonymized transcript by anonymizing personally identifiable words, and generate a sentiment score based on the anonymized transcript.
