Latest Patents

One of Debajit Ghosh's latest patents is titled "Method and apparatus for improving human-machine dialogs using language models learned automatically from personalized data." This invention involves a speech-based processing system that utilizes a database of personal information management (PIM) data, a set of language models, a learning unit, a recognition server, and a speech application. The learning unit employs a language model learning algorithm to create language models based on the user's PIM data. The recognition server is designed to recognize user utterances using these language models, while the speech application identifies and accesses specific subsets of PIM data based on the recognition results. The algorithm may utilize grammar induction and train statistical language models based on the PIM data, generating language models either periodically or on-the-fly during user sessions.

Another significant patent by Ghosh is "Method and apparatus for providing active help to a user of a voice-enabled application." This invention focuses on a voice-enabled application, such as a voice browser, that is configured to offer active assistance to users. The application maintains a usage history for each user concerning dialog states, which includes various user-specific variables. It also keeps a number of active help prompts that can be delivered as speech, each addressing a different help topic. The application monitors dialog states during user sessions and generates events based on these states. If certain conditions are met, the application plays an active help prompt to the user, providing relevant information.
