A handheld device 100 such as a personal digital assistant (PDA) or the like, a handwritten input user interface (HIUI), a method of interfacing handwritten text and a program product therefor. A lower portion of a touch enabled display is designated as a handwriting input area 104. Action icons 106, 108, 110, 112 and 114 are disposed at a right side of the handwriting user interface 102. Recognized text is displayed on the screen in a text display area located between a file management tool bar 116 and the handwritten input area 104. A scroll bar 118 is disposed at the right side of the display 112. As text is continuously entered each individual word may be recognized, and inserted into the end of the text stream. A word separator 120 may demarcate or bracket individual words in a continuous input stream. A secondary list of potential recognition candidates may be available for display in a box 128 and offered for substitution for or in lieu of the recognized word. Handwritten text may be continuously entered and displayed in the handwriting input area 104 as digital ink, the input point staying approximately fixed with the ink display automatically scrolling. The input area behaves as a "treadmill" or "ticker tape" that is moving from right to left, thereby giving the illusion of a continuous writing space. The speed of the "treadmill" automatically adapts to writing speed. The device 100 may include a communications function and, in particular the device may include an antenna 122 for wireless communication. Individual function switches, buttons and other controls are disposed about the device.

A method, system, computer program product, and method of doing business by providing improved audio compression wherein an audio stream is securely transformed to an encoded text stream (such as an ASCII, EBCDIC, or Unicode text stream). One or more components which are involved in the transformation process are authenticated. A unique identifier of each such component is included within cryptographically-protected information that is provided for the encoded text stream. A digital signature is preferably used for the cryptographic protection, thereby digitally notarizing the encoded text stream. The authenticity and integrity of the encoded text stream can therefore be verified. In preferred embodiments, the authenticated identities of components performing the transformation can also be determined from the cryptographically-protected information. The encoded text stream will typically require much less storage space than the audio stream, and providing the digital notarization along with the encoded text stream serves to reliably establish evidence of the contents of the audio stream (even though a perfect speech-to-text transformation might not be achieved).

A method for analyzing and indexing an unstructured or semistructured document according to one embodiment includes receiving an unstructured or semistructured document; converting the document to one or more text streams; analyzing the one or more text streams for identifying textual contents of the document; analyzing the one or more text streams for identifying logical sections of the document; associating the textual contents with the logical sections; indexing the textual contents and their association with the logical sections; and saving a result of the indexing in a data storage device.

A relay is described to facilitate communication through the telephone system between hearing users and users who need or desire assistance in understanding voice communications. To overcome the speed limitations inherent in typing, the call assistant at the relay does not type most words but, instead, re-voices the words spoken by the hearing user into a computer operating a voice recognition software package trained to the voice of that call assistant. The text stream created by the computer and the voice of the hearing user are both sent to the assisted user so that the assisted user can be supplied with a visual text stream to supplement the voice communications. A time delay in the transmission of the voice of the hearing user through the relay is of assistance to the assisted user in comprehending the communications session.

The invention discloses a method and a device for mining hot-spot words. The method includes acquiring input text streams; subjecting the text streams to word segmentation to obtain a candidate word set; accounting a current frequency that each candidate word in the candidate word set appears in the text streams to acquire each history frequency of each candidate word in prestored history data; and calculating a frequency abnormity value of the candidate word according to the current frequency and each history frequency of the candidate word, storing a current frequency message of the candidate word in the history data, and outputting a preset number of candidate words with abnormal frequencies. By means of the method and the device for mining the hot-spot words, mining ranges of the hot-spot words can be extended, and mining efficiencies of the hot-spot words can be improved.

Speech recognition is performed in near-real-time and improved by exploiting events and event sequences, employing machine learning techniques including boosted classifiers, ensembles, detectors and cascades and using perceptual clusters. Speech recognition is also improved using tandem processing. An automatic punctuator injects punctuation into recognized text streams.
