Latest Patents
One of David's latest patents is titled "Methods and systems of routing utterances based on confidence estimates." This innovative computer-based method involves receiving a message and processing it using large-vocabulary continuous speech recognition to generate a corresponding string of text. The method includes generating a confidence estimate of the string and comparing it to a predetermined threshold. If the confidence estimate meets the threshold, the string is forwarded to the system. If not, the information is sent to a transcriptionist. This approach allows for the separate or joint processing of utterances, enhancing the accuracy of message routing.
Another significant patent is the "Automatic dialer for telephone network access control." This automatic dialer controls access to long-distance telephone networks. It features a read/write memory that records attempts to call inaccessible numbers. Before placing a call, the dialer compares the destination number with entries in the memory, ensuring that calls are only placed if the area code and exchange do not match any recorded entries. This system improves user experience by managing access efficiently.
