Abstract: A method for retrieving information may include receiving a telephone call from a caller and identifying a telephone number from which the telephone call was made. The method may also include retrieving information from a database based on the identified telephone number. The method may further include providing an audible message to the caller to verify whether the retrieved information is correct.

Abstract: A method for performing speech recognition includes receiving a voice input and generating at least one possible result corresponding to the voice input. The method may also include calculating a value for the speech recognition result and comparing the calculated value to a particular portion of the speech recognition result. The method may further include retrieving information based on one or more factors associated with the voice input and using the retrieved information to determine a likelihood that the speech recognition result is correct.

Abstract: An approach providing the efficient use of speech synthesis in rendering text content as audio in a communications network. The communications network can include a telephony network and a data network in support of, for example, Voice over Internet Protocol (VoIP) services. A speech synthesis system receives a text string from either a telephony network, or a data network. The speech synthesis system determines whether a rendered audio file of the text string is stored in a database and to render the text string to output the rendered audio file, if the rendered audio is determined not to exist. The rendered audio file is stored in the database for re-use according to a hash value generated by the speech synthesis system based on the text string.

Abstract: A Voice User Interface (VUI) or Interactive Voice Response (IVR) system utilizes three levels of navigation (e.g. Main Menu, Services, and Helper Commands) in presenting information units arranged in sets. The units are “spoken” by a system in a group to a human user and the group of information at each level is preceded by a tone that is unique to the level. When navigating the levels, the tones of the levels are in a musical progression, e.g. the three-note blues progression I, IV, V, for preceding the groups of information, respectively. The musical progression returns to the tonic of the musical key when the navigation returns to the level one of the first group of information.

Abstract: An expandable tree-shaped device is formed from a sheet of material which includes a central apex and a plurality of spaced apart spiral strips extending therefrom, with the spiral strips being substantially coaxial to the central apex and to one another. The central apex and the spiral strips, in the operative position, are positioned in a vertically spaced, tiered array, with the central apex at an uppermost position such that the tiered array is configured to have a generally conical tree-shape. A plurality of connecting segments join each spiral strip or tier of the array to a next adjacent spiral strip or tier of the array to form a unitary structure. The width of each spiral strip increases proportionately with the increase in radial distance from the central point.

Abstract: A method and apparatus suitable for producing an artificial snow surface for tire evaluation is provided. The process provides for manufacturing a series of snow layers, each layer followed by a packing and a grooming step to provide a multi-layered snow surface. Desirable shear strength properties of the snow surface are enhanced by a surface grooming technique that applies a layer of water to the upper snow surface followed by grooming of the surface. The manufactured snow surface allows the testing and evaluation of tires that compares favorably to tire evaluation data obtained from outdoor testing facilities.

Abstract: Air dryer mechanism for a compressed air system includes a cover member, a desiccant housing, and an adapter member securing the desiccant housing to the cover member. In one embodiment, the adapter member is a integral purge volume which is releasably attached to both the cover member and to the desiccant housing and which defines a purge volume which stores purge air for later regeneration of the desiccant. In another embodiment, the adaptive member is a plate which is attached to both the cover member and the desiccant housing and provides flow paths communicating the supply port to the desiccant and the desiccant to the delivery port. The second embodiment, the cover member is provided with a purge volume port for connection to a remote purge volume.
