Latest Patents
One of Aratrika Sarkar's latest patents focuses on a device, system, and method for analyzing audio speech signals to detect fraudulent calls to a contact center. This innovative approach involves splitting an audio recording of a call in real-time into a foreground speech signal attributed to the main speaker and a background audio signal. The process includes extracting audio features from both signals and inputting them into an ensemble model comprising multiple different machine learning models co-trained to cumulatively detect fraud. These models include a speaker audio model to detect audio speech anomalies, a speaker intent model to classify the intent of the main speaker, a synthetic voice detection model to identify non-human entities, and a prosody model to detect the voice intonation of the main speaker. The ensemble model outputs a prediction indicating whether the call is fraudulent.
