Abstract: A system to assist in secure multi-mode communication is described. The system can receive communications from a source agent in a source communication mode, authenticate the source agent, and determine a recipient communication mode associated with the recipient agent. The system then transforms the communication from the first communication mode to the second communication mode based on the recipient agent and/or the content of the communication and provides the communication to the recipient agent in the recipient communication mode.

Abstract: A voice-enabled document system facilitates execution of service delivery operations by eliminating the need for manual or visual interaction during information retrieval by an operator. Access to voice-enabled documents can facilitate operations for mobile vendors, on-site or field-service repairs, medical service providers, food service providers, and the like. Service providers can access the voice-enabled documents by using a client device to retrieve the document, display it on a screen, and, via voice commands initiate playback of selected audio files containing information derived from text data objects selected from the document. Data structures that are components of a voice-enabled document include audio playback files and a logical association that links the audio playback files to user-selectable fields, and to a set of voice commands.

Abstract: A headset terminal for speech applications includes a headband assembly, an earcup assembly and a power source assembly. Processing circuitry is positioned in at least one of the earcup assembly and the power source assembly and includes speech processing circuitry for recognizing and synthesizing speech. A radio communicates with a central system to process the activity information of the headset terminal user. A rotatable microphone boom assembly includes controls mounted on opposite sides of a rotation axis to maintain a consistent orientation on the boom assembly with respect to the head of a user. The boom assembly snaps together with the earcup assembly to rotate. The headband assembly includes at least one transverse band and a sliding arm coupled to the earcup assembly for dynamically adjusting the position of the earcup assembly. A latch of the power source assembly snaps into position to secure it with the assembly and slides between latched and unlatched positions to secure a battery.

Abstract: A wireless device for use with speech recognition applications comprises a frame generator for generating successive frames from digitized original audio signals, the frames representing portions of the digitized audio signals. An autocorrelation circuit generates a set of coefficients for each frame, the coefficient set being reflective of spectral characteristics of the audio signal portion represented by the frame. In one embodiment, the autocorrelation coefficients may be used to predict the original audio signal to be subtracted from the original audio signals and to generate residual signals A Bluetooth transceiver is configured for transmitting the set of coefficients and/or residual signals as data to another device, which utilizes the coefficients for speech applications.

Abstract: A device is comprised of processing circuitry operable for providing a speech interface to facilitate a speech dialog with a user or generates commands for a user. An RFID reader, operably coupled with the processing circuitry, is operable for reading data from an RFID tag. In one aspect, the reading occurs in the context of a speech dialog. In another aspect, the data is used to generate speech commands. In another aspect, information is stored to an RFID tag during the speech dialog.

Abstract: A consumer uses a portable device to record voice input of items that are needed when shopping at a store. The device is then carried to the store when shopping and upon entering the store becomes connected to a wireless LAN within the store. Once on the LAN, the device can exchange information with a store computer such as by sending the list of voice inputs to the computer and receiving back information about the location of those items in the store. The received information is provided as audio output by the device. By including a locator service within the wireless LAN, the store computer is able to identify where the device is located and customize any announcements that the store computer sends to the device.

Abstract: An apparatus for detecting user speech comprises a first microphone and at least a second microphone, each operable to generate sound signals with respective signal characteristics. The first microphone is operable to capture a greater proportion of speech sounds of a user than the second microphone. Processing circuitry processes the signal characteristics of the sound signals generated by the first microphone and the second microphone to determine variations in those signal characteristics for determining if the user is speaking.

Abstract: A headset for communication with a device is configured for processing audio signals captured by the headset to detect user speech and transmitting, to the device, sampled representations of the captured audio signals generally only when user speech is detected.

Abstract: A dialog engine includes methods for integrating multi-modal data capture device inputs with multimodal output capabilities in which a work flow description is extracted from objects in a graphical user interface and a multi-modal user interface is defined. The dialog engine synchronizes the flow of information, in accordance with the work flow description, between input/output devices and an application.
