Abstract
A method of creating an algorithm to enhance detection of fraudulent audio data is provided that includes 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, generating additional audio data using the synthetic speech creation algorithm, and creating a database including the generated audio data and genuine data. When the synthetic speech detection algorithm failed to detect the generated audio data, the synthetic speech detection algorithm is divided into a first algorithm and a second algorithm. The second algorithm is fine-tuned using the data in the created database. The first algorithm and the fine-tuned second algorithm are combined to create a fine-tuned synthetic speech detection algorithm for enhancing detection of fraudulent audio data generated by the synthetic speech creation algorithm.
