Abstract: A voice and dialect matching computing device processes audio signals received from two sources to authenticate and secure information associated with creation of an electronic transaction. This voice based computing device automatically processes audio signals to identify participants based on voice information and/or dialect information. The voice based computing device compares a vocal signal and/or dialect information using an intelligent processing unit (e.g., an artificial intelligence/machine learning based model) and/or using historical information stored in a central dynamic data store. The processed audio signals are decomposed into at least two signals, where a first signal may be used as a trigger to activate processing of an electronic transaction by a smart contract hub computing device. The second signal includes attributes of the electronic transaction which may then be encrypted.
