Abstract: A method, computer program product, and system for adapting speech recognition of a user's speech is provided. The method includes receiving a first utterance from a user having a duration below a predetermined threshold, identifying at least one further utterance from the user that provides additional information, generating a concatenated utterance by concatenating the first utterance with the at least one further utterance, transmitting the concatenated utterance to a speech recognition server, receiving a transcription of the concatenated utterance from the speech recognition server that includes a transcription of the first utterance, and extracting the transcription of the first utterance from the transcription of the concatenated utterance. The transcription of the first utterance is based on the additional information provided by the at least one further utterance.

Abstract: Systems and methods for maintaining speaker recognition performance are provided. A method for maintaining speaker recognition performance, comprises training a plurality of models respectively corresponding to speaker recognition scores from a plurality of speakers over a plurality of sessions, and using the plurality of models to conclude whether a speaker seeking access to an environment is a non-ideal target speaker or a non-ideal non-target speaker. Using the plurality of models to conclude comprises calculating a first probability that the speaker seeking access is the non-ideal target speaker, calculating a second probability that the speaker seeking access is the non-ideal non-target speaker, and determining whether the first probability, the second probability or a sum of the first probability and the second probability is above a probability threshold.

Abstract: Methods, apparatus, and computer program products are disclosed for synchronizing distributed speech recognition (‘DSR’) that include receiving in a DSR client notification from a voice server of readiness to conduct speech recognition and, responsive to the receiving, transmitting by the DSR client, from the DSR client to the voice server, speech for recognition.

Abstract: Method, system, and computer program product for voice transformation are provided. The method includes transforming a source speech using transformation parameters, and encoding information on the transformation parameters in an output speech using steganography, wherein the source speech can be reconstructed using the output speech and the information on the transformation parameters. A method for reconstructing voice transformation is also provided including: receiving an output speech of a voice transformation system wherein the output speech is transformed speech which has encoded information on the transformation parameters using steganography; extracting the information on the transformation parameters; and carrying out an inverse transformation of the output speech to obtain an approximation of an original source speech.

Abstract: Systems and methods for detecting end of a transaction in a computing environment are provided. The method comprises determining a target area in a graphical user environment displayed on a display screen, wherein a change is expected to occur when end of a transaction is reached; masking the target area at least partially to remove content included in the target area that is present before or after the transaction was initiated; monitoring the target area for change in content; and detecting the end of the transaction when the content of the target area has changed.

Abstract: A voice processing system includes a real-time voice server, which is arranged to process real-time voice processing tasks for clients of the system. A gateway processor is arranged to accept from a client a request to perform an off-line voice processing task, to convert the off-line voice processing task into an equivalent real-time voice processing task, to invoke the voice server to process the equivalent real-time voice processing task, and to output a result of the equivalent real-time voice processing task.

Abstract: Methods and systems are provided for remote tuning and debugging of an automatic speech recognition system. Trace files are generated on-site from input speech by efficient, lossless compression of MFCC data, which is merged with compressed pitch and voicing information and stored as trace files. The trace files are transferred to a remote site where human-intelligible speech is reconstructed and analyzed. Based on the analysis, parameters of the automatic speech recognition system are remotely adjusted.

Abstract: A computer-implemented method for processing paper forms includes capturing at a computer system an image of a paper form in which information has been filled-in. A location identifier is extracted from the image. The location identifier indicates an address in a storage location external to the computer system, at which the filled-in information is electronically stored. The information is retrieved responsively to the location identifier by communication with the storage location via a wide area network (WAN), so as to convey the information electronically from the storage location to the computer system. The information is processed using a data processing application running on the computer system.
