Abstract: A method and apparatus for removing the effect of background music or noise from speech input to a speech recognizer so as to improve recognition accuracy has been devised. Samples of pure music or noise related to the background music or noise that corrupts the speech input are utilized to reduce the effect of the background in speech recognition. The pure music and noise samples can be obtained in a variety of ways. The music or noise corrupted speech input is segmented in overlapping segments and is then processed in two phases: first, the best matching pure music or noise segment is aligned with each speech segment; then a linear filter is built for each segment to remove the effect of background music or noise from the speech input and the overlapping segments are averaged to improve the signal to noise ratio. The resulting acoustic output can then be fed to a speech recognizer.

Abstract: A conversational browsing system (10) comprising a conversational browser (1 1) having a command and control interface (12) for converting speech commands o r multi-modal input from I/O resources (27) into navigation request. The syste m (10) comprises conversational engines (23) for decoding input commands for interpretation by the command and control interface and decoding meta- information provided by the CML processor for generating synthesized audio output. The system includes a communication stack (19) for transmitting the navigation request to a content server and receiving a CML file from the content server based on the navigation request. A conversational transcoder (13) transforms presentation material from one modality to a conversational modality. The transcoder (13) includes a functional transcoder (13a) to transform a page of GUI to a page of CUI (conversational user interface) and a logical transcoder (13b) to transform business logic of an application, transaction or site into an acceptable dialog.

Abstract: A system and method for providing automatic and coordinated sharing of conversational resources, e.g. functions and arguments, between network-connected servers and devices, and their corresponding applications. In one aspect, a system for providing automatic and co-ordinated sharing of conversational resources comprises: a network comprising a first (100), and second (106) network device; the first (100) and second (106) network device each comprising a set of conversational resources ( 102, 107), a dialog manager ( 103, 108), for managing a conversation and executing calls requesting a conversational service, and a communication stack (111, 115), for communicating messages over a network using conversational protocols, wherein the conversational protocols establish coordinated network communication between the dialog managers of the first and second device to automatically share the set of conversational resources of the first and second network device, when necessary, to perform their respective requested conversational service.
