Abstract: This invention is concerned with an electrically conductive polymer blend composition which is a liquid compatible blend, comprising a doped product formed form blending a first solution comprising a Lewis base electrically conductive polymer in undoped form in a first organic solvent with a second solution comprising a Lewis acid polymer dopant in a second organic solvent, wherein said Lewis acid polymer dopant dopes said Lewis base electrically conductive polymer in undoped form to obtain said electrically conductive polymer blend, the resulting doped conductive product being soluble in the combination of said first and said second organic solvents and mixable at the molecular level.

Abstract: A method for managing spoken language interface data structures and collections of user interface service engines in a spoken language dialog manager in a personal speech assistant. Interfaces, designed as part of applications, may by these methods be added to or removed from the set of such interfaces used by a dialog manager. Interface service engines, required by new applications, but not already present in the dialog manager, may be made available to the new and subsequently added applications.

Abstract: A Personal Speech Assistant (PSA) is a computing apparatus which provides a spoken language interface to another apparatus to which it is attached by supporting execution of a conversational dialog manager and its supporting service engines. In operation, a PSA is connected to a device which provides some service to a user. Any “appliance” is a candidate for enhancement with the PSA. Devices such as, for example, video cassette recorders (VCRs) or Personal Digital Assistants (PDAs), which offer rich, but frequently difficult interfaces, may be made more useful by the integration of a PSA according to the invention. It is a preferred feature of a dialog manager used by the PSA that the user interface properties, in terms of the vocabulary the device understands, the informative prompts it provides, and other aspects of its conversational behavior, are all easily modified to correspond to the preferences or limitations of the user.

Abstract: A spoken language interface between a user and at least one application or system includes a dialog manager operatively coupled to the application or system, an audio input system, an audio output system, a speech decoding engine and a speech synthesizing engine; and at least one user interface data set operatively coupled to the dialog manager, the user interface data set representing spoken language interface elements and data recognizable by the application. The dialog manager enables connection between the input audio system and the speech decoding engine such that a spoken utterance provided by the user is provided from the input audio system to the speech decoding engine. The speech decoding engine decodes the spoken utterance to generate a decoded output which is returned to the dialog manager.

Abstract: A speaker recognition system for selectively permitting access by a requesting speaker to one of a service and facility include an acoustic front-end for computing at least one feature vector from a speech utterance provided by the requesting speaker; a speaker dependent codebook store for pre-storing sets of acoustic features, in the form of codebooks, respectively corresponding to a pool of previously enrolled speakers; a speaker identifier/verifier module operatively coupled to the acoustic front-end, wherein: the speaker identifier/verifier module identifies, from identifying indicia provided by the requesting speaker, a previously enrolled speaker as a claimed speaker; further, the speaker identifier/verifier module associates, with the claimed speaker, first and second groups of previously enrolled speakers, the first group being defined as speakers whose codebooks are respectively acoustically similar to the claimed speaker (i.e.

Abstract: The most likely to be used characters and controls of a soft keyboard are determined from consulting trigram tables, and enhanced and/or positioned to attract the user and to facilitate quick recognition and selection. The letters and other characters of the soft keyboard display can be arranged in a standard keyboard format, some variation of that format such as a Dvorak layout or an entirely different arrangement such as strings of letters and numbers in alphabetical and numerical order. However, regardless of the layout, an attractant, such as color intensity, or size, is used for emphasis to make a soft keyboard user cognizant of the location of the subset of characters that the user is most likely to select to standout from the other keys of the keyboard. In addition to enhancing all characters of the subset, particular emphasis can be placed on the most likely character in the subset to be selected.

Abstract: The present invention contemplates a display generating system, preferably a computer such as a mobile client system, in which text entry to supply data for a defined field in a form or the like is facilitated. In particular, the present invention contemplates combining certain functions heretofore separated in a display which accepts data entry such as letters or numbers entered by hand using a stylus or the like. In a system implementing this invention, the functions of providing a cursor which indicates the location for data entry and providing a field displaying or receiving data entry are combined. By this combination, the field receiving or displaying an entry is positioned immediately adjacent the displayed field for such entry, permitting a user to focus attention on a single location in the display as distinguished from dividing attention between a location at which a cursor prompts for data to appear and a separated field at which the entry is entered or displayed.

Abstract: A continuous speech recognition system has the ability to correct errors in strings of words. The error correction method stores data in the system's internal state to update probability tables used in developing alternative lists for substitution in misrecognized text.

Abstract: An optical assembly structure wherein miniature optical components such as lasers, modulators, lenses, thin-film and fiber-optic waveguides, and photodetectors are critically aligned and supported for coactive operation by means of two or more wafers which are formed with complementary grooves and mortises to support the loose optical components such as lenses and fiber-optic waveguides and to receive alignment rails to insure the relativity of the wafers, which also have formed integral therewith optical elements such as waveguides, modulators, and lasers, to produce an integrated optical assembly somewhat in the manner of an "optical bench," wherein the bench structure also provides an active optical element.

Abstract: An array of collimated wise aperture electrically pumped leaky corrugated AlGaAs optical waveguide lasers is formed on a single chip by etching a series of grooves oriented with respect to the crystalographic planes to isolate discrete lasers in the array and provide the requisite orientation of the internal reflecting surfaces to support the lasing action. The corrugation period is chosen such that the laser radiation exits from the array in a direction normal to the plane of waveguide.
