| 8135860 | Content interpolating web proxy server A content interpolating web proxy server is configured in a computer network for processing retrieved web content so as to place it in a format suitable for presentation on a particular client device such as, e.g., a computer, personal digital assistant (PDA), wirel... | 03/13/2012 |
| 6604075 | Web-based voice dialog interface A web-based voice dialog interface for use in communicating dialog information between a user at a client machine and one or more servers coupled to the client machine via the Internet or other computer network. The interface in an illustrative embodiment... | 08/05/2003 |
| 6587822 | Web-based platform for interactive voice response (IVR) A platform for implementing interactive voice response (IVR) applications over the Internet or other type of network includes a speech synthesizer, a grammar generator and a speech recognizer. The speech synthesizer generates speech which characterizes th... | 07/01/2003 |
| 6574601 | Acoustic speech recognizer system and method An adaptive endpointer system and method are used in speech recognition applications, such as telephone-based Internet browsers, to determine barge-in events during the processing of speech. The endpointer system includes a signal energy level estimator f... | 06/03/2003 |
| 6243493 | Method and apparatus for handwriting recognition using invariant features Handwriting recognition which is invariant with respect to translation, rotation and scale is achieved with a new feature signal, ratio of tangents, and a new application of the normalized curvature feature. Use of these features is optimized by augmentin... | 06/05/2001 |
| 6044347 | Methods and apparatus object-oriented rule-based dialogue management An object-oriented dialogue manager is provided which allows a computer system or other dialogue processing system to conduct an efficient dialogue with a human user. In an illustrative embodiment, the dialogue manager processes a set of frames characteri... | 03/28/2000 |
| 5999904 | Tracking initiative in collaborative dialogue interactions A processing system which acts as a participant in the collaborative dialogue is first trained using a training algorithm.
