1. A method of creating an algorithm to enhance detection of fraudulent audio data comprising the steps of:
generating, by an electronic device, audio data using a synthetic speech creation algorithm;
processing the generated audio data using a synthetic speech detection algorithm;
determining whether the synthetic speech detection algorithm detects the generated audio data;
in response to determining the synthetic speech detection algorithm failed to detect the generated audio data, generating additional audio data using the synthetic speech creation algorithm and creating a database including the generated audio data and genuine data;
dividing the synthetic speech detection algorithm into a first algorithm and a second algorithm;
fine-tuning the second algorithm using the generated audio data and genuine data in the created database, the fine-tuned second algorithm being different than the second algorithm; and
combining the first algorithm and the fine-tuned second algorithm to create a fine-tuned synthetic speech detection algorithm for enhancing detection of fraudulent audio data generated by the synthetic speech creation algorithm.
