Latest Patents

Among Shane Walker's most significant patents is the development of an Automatic Speech Recognition (ASR) model training system. This innovative technology continuously refines an ASR model to ensure rapid and precise transcriptions of spoken language. The system evaluates detected speech activity to produce text transcriptions along with quality metrics, such as minimum Bayes risk and perplexity, which indicate the reliability of each transcription. Furthermore, it incorporates a filtering process to select text transcriptions based on associated quality metrics, while also correcting for known systemic errors within the ASR system. Importantly, it includes a mechanism for manual review and correction, allowing for continual training of the ASR model to enhance accuracy and speed.

In addition, Walker holds a patent for a method designed to identify call features and associations crucial for detecting call traffic pumping. This system continuously monitors telephone calls, analyzing training calls to develop a classification model that links specific call features to the likelihood of call traffic pumping activity. By comparing features from monitored calls against this model, the system can accurately determine when to take corrective measures, such as terminating suspicious calls or flagging them for further review.
