Appl. No.:

09/015393

Inventors:

Manish Sharma - Somerset NJ
Richard J. Mammone - Bridgewater NJ

Assignee:

T-NETIX, Inc. - Dallas TX

International Classification:

G01L 1700

US Classification:

704270, 704273, 704275, 379 67, 379 88

Abstract:

The present invention is a reliable system and method for detecting a recorded voice, which can be employed independently or to provide protection from fraudulent use of a recording to defeat an automatic speaker recognition system. Several techniques and systems are employed either independently or in combination to verify that a detected audio sample is live and not recorded. Temporal speech characteristics of an audio sample are analyzed to determine whether a sample under examination is so similar to a previous sample as to indicate a recording. Communications channel characteristics are examined to determine whether an sample was recorded on a different channel from a predetermined communications channel. A pattern classifier is trained to distinguish between live and recorded speech. Finally, an âaudio watermarkâ is used to determine whether a detected audio sample is a recording of a previous communication by an authorized user.

International Classification:

G02B 626

US Classification:

385 27, 385 10, 385 16, 385 37

Abstract:

A hitless wavelength selective optical device includes a first thermo-optic switch (TOS), a second TOS, a first waveguide, a second waveguide, a third waveguide, a heating element and a control unit. The first TOS includes receives a wavelength division multiplexed (WDM) signal at a first port of the first TOS. The second TOS provides at least one channel of the WDM signal at a first port of the second TOS. The first waveguide is coupled between second ports of the first and second TOS. The second waveguide includes a tunable filter that reflects a selected channel from the received WDM signal and coupled between the third ports of the first and second TOS.

International Classification:

H04J014/02

US Classification:

359/128000, 359/127000

Abstract:

A wavelength selective optical cross-connect includes a first demultiplexor feeding into individually removable modules that in turn feed a first multiplexor, such that the cross-connect is expandable and repairable on a wavelength or waveband basis. The modules desirably include multiple optical components in the optical path, with components in each module matched to others in that module to provide module-to-module variation below that of the variation in module components. The modules desirably include an additional demultiplexor and multiplexor. The modules also desirably include wavelength or narrowband amplification together with power equalization. The modules may also include a switch fabric. Alternatively, the switch fabric may be provided in the form of a separate removable switch module or modules, with various technologies employed in various switch modules, including manual switching with automatic connection discovery, with simple plug-in upgradeability to modules having automatic or remotely actuated switching.

US Classification:

385/016000

Abstract:

An optical communication system that includes an optical network is disclosed having a plurality of nodes and a plurality of optical fiber links which includes optical fiber links that interconnect the nodes. Signals passing through the network are similarly pre-compensated and/or similarly post-compensated. The network preferably includes dispersion-managed optical fiber spans, and preferably further includes distributed amplification, preferably erbium amplifiers and/or Raman amplifiers. Preferably, the network is transparent.

Inventors:

Jonathan D. HOMA - Livingston NJ, US
Manish Sharma - Morgan Hill CA, US

International Classification:

H04J 14/02

US Classification:

398 48

Abstract:

An optical switching device with a switch-and-select architecture uses a single multi-port optical channel router, such as a wavelength selective switch, as a bidirectional switching device. The optical switching device includes the multi-port optical channel router and optical circulators coupled to the input/output ports of the multi-port optical channel router. The optical circulators couple one or more output ports and one or more input ports of the optical switching device to the input/output ports of the optical channel router so that the optical channel router provides symmetric, bi-directional switching at an optical network node.

International Classification:

G10L 500

US Classification:

704232

Abstract:

The present invention relates to a pattern recognition system which uses data fusion to combine data from a plurality of extracted features and a plurality of classifiers. Speaker patterns can be accurately verified with the combination of discriminant based and distortion based classifiers. A novel approach using a training set of a "leave one out" data can be used for training the system with a reduced data set. Extracted features can be improved with a pole filtered method for reducing channel effects and an affine transformation for improving the correlation between training and testing data.

International Classification:

G10L 506
G10L 900

US Classification:

704231

Abstract:

The present invention relates to a method for segmenting speech into subword speech segments. Optimal boundary locations for each estimate of a number of segments are determined within an estimated range of the number of segments. In addition, an optimality criteria is found for each estimate of the number of segments within the range. Using the optimality criteria, the optimal number of subwords are determined. From the location of the boundaries and the optimal number of segments, data can be clustered or speech can be segmented. The method can be used in data processing systems, speaker verification, medium size vocabulary speech recognition systems, language identification systems and coarse subword level speech segmentation processes.
