1. A system, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
in response to intercepting a call from communication equipment, requesting the communication equipment to supply audio response data;
converting the audio response data to text data representative of the audio response data;
analyzing the text data relative to a keyword representing earlier audible input data that was received by the system prior to the intercepting of the call, wherein the keyword is verified based on user input associated with a user identity;
determining a defined threshold value based on a statistical similarity between the keyword and a variant of the keyword, wherein the statistical similarity of the variant of the keyword was verified based on the user input;
determining, based on the analyzing of the text data that the defined threshold value has been achieved; and
based on the determining, allowing the call to proceed to a user equipment associated with the user identity.
