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:

G10L021/00

US Classification:

704/273000

Abstract:

The present invention applies speech recognition technology to remote access, verification, and identification applications. Speech recognition is used to raise the security level of many types of transaction systems which previously had serious safety drawbacks, including: point of sale systems, home authorization systems, systems for establishing a call to a called party (including prison telephone systems), internet access systems, web site access systems, systems for obtaining access to protected computer networks, systems for accessing a restricted hyperlink, desktop computer security systems, and systems for gaining access to a networked server. A general speech recognition system using communication is also presented. Further, different types of speech recognition methodologies are useful with the present invention, such as “simple” security methods and systems, multi-tiered security methods and systems, conditional multi-tiered security methods and systems, and randomly prompted voice token methods and systems.

International Classification:

G02B006/26
G02B006/42

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.

Assignee:

T-Netix, Inc. - Englewood CO

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.
