A recognition system is a computer application that can be used to recognise things like speech fingerprints and writing.

Distributed real time speech recognition system

InactiveUS20050080625A1Facilitates query recognitionAccurate best responseNatural language translationData processing applicationsFull text searchTime system
A real-time system incorporating speech recognition and linguistic processing for recognizing a spoken query by a user and distributed between client and server, is disclosed. The system accepts user's queries in the form of speech at the client where minimal processing extracts a sufficient number of acoustic speech vectors representing the utterance. These vectors are sent via a communications channel to the server where additional acoustic vectors are derived. Using Hidden Markov Models (HMMs), and appropriate grammars and dictionaries conditioned by the selections made by the user, the speech representing the user's query is fully decoded into text (or some other suitable form) at the server. This text corresponding to the user's query is then simultaneously sent to a natural language engine and a database processor where optimized SQL statements are constructed for a full-text search from a database for a recordset of several stored questions that best matches the user's query. Further processing in the natural language engine narrows the search to a single stored question. The answer corresponding to this single stored question is next retrieved from the file path and sent to the client in compressed form. At the client, the answer to the user's query is articulated to the user using a text-to-speech engine in his or her native natural language. The system requires no training and can operate in several natural languages.

Method and apparatus for training a multilingual speech model set

The invention relates to a method and apparatus for training a multilingual speech model set. The multilingual speech model set generated is suitable for use by a speech recognition system for recognizing spoken utterances for at least two different languages. The invention allows using a single speech recognition unit with a single speech model set to perform speech recognition on utterances from two or more languages. The method and apparatus make use of a group of a group of acoustic sub-word units comprised of a first subgroup of acoustic sub-word units associated to a first language and a second subgroup of acoustic sub-word units associated to a second language where the first subgroup and the second subgroup share at least one common acoustic sub-word unit. The method and apparatus also make use of a plurality of letter to acoustic sub-word unit rules sets, each letter to acoustic sub-word unit rules set being associated to a different language. A set of untrained speech models is trained on the basis of a training set comprising speech tokens and their associated labels in combination with the group of acoustic sub-word units and the plurality of letter to acoustic sub-word unit rules sets. The invention also provides a computer readable storage medium comprising a program element for implementing the method for training a multilingual speech model set.

Method and apparatus for providing unsupervised adaptation of phonetic transcriptions in a speech recognition dictionary

InactiveUS6208964B1Improve task adaptabilitySpeech recognitionSpeech identificationSpeech sound
An adaptive speech recognition system is provided including an input for receiving a signal derived from a spoken utterance indicative of a certain vocabulary item, a speech recognition dictionary, a speech recognition unit and an adaptation module. The speech recognition dictionary has a plurality of vocabulary items each being associated to a respective dictionary transcription group. The speech recognition unit is in an operative relationship with the speech recognition dictionary and selects a certain vocabulary item from the speech recognition dictionary as being a likely match to the signal received at the input. The results of the speech recognition process are provided to the adaptation module. The adaptation module includes a transcriptions bank having a plurality of orthographic groups, each including a plurality of transcriptions associated with a common vocabulary item. A transcription selector module in the adaptation module retrieves a given orthographic group from the transcriptions bank on a basis of the vocabulary item recognized by the speech recognition unit. The transcription selector module processes the given orthographic group on the basis of the signal received at the input to select a certain transcription from the transcriptions bank. The adaptation module then modifies a dictionary transcription group corresponding to the vocabulary item selected as being a likely match to the signal received at the input on the basis of the selected certain transcription.

Systems and methods for managing and detecting fraud in image databases used with identification documents

We provide a system for issuing identification documents to a plurality of individuals, comprising a first database, a first server, and a workstation. The first database stores a plurality of digitized images, each digitized image comprising a biometric image of an individual seeking an identification document. The first server is in operable communication with the first database and is programmed to send, at a predetermined time, one or more digitized images from the first database to a biometric recognition system, the biometric recognition system in operable communication with a second database, the second database containing biometric templates associated with individuals whose images have been previously captured, and to receive from the biometric recognition system, for each digitized image sent, an indicator, based on the biometric searching of the second database, as to whether the second database contains any images of individuals who may at least partially resemble the digitized image that was sent. The a workstation is in operable communication with the first server and is configured to permit a user to review the indicator and to make a determination as to whether the individual is authorized to be issued an identification document or to keep an identification document in the individual's possession.

Cashless payment system

InactiveUS20050015332A1Without any loss of transaction processing flexibilityWidespread acceptanceFinanceBuying/selling/leasing transactionsComputer networkEngineering
A payment system that does not rely on credit or debit cards, does not require the merchant and purchaser to have compatible memberships to complete a transaction, and does not limit single transactions to a single account provides a wide range of flexibility permitting debit, credit, pre-paid and payroll cards to be accommodated in a seamless and invisible manner to the electronic transaction network. The transaction may be verified and approved at the point-of-sale whether or not the merchant is a member of a specific financial transaction system. Specifically, the point-of-sale transaction system permits an identified customer to use any of a variety of payment options to complete the transaction without requiring the merchant to pre-approve the type of payment selected by the customer. In one configuration, and in order to take advantage of the widespread use of the ATM/POS network, the invention uses a typical credit/debit card format to provide the identifying information in a stored value card. When a transaction is to be completed, the user enters the identifying information carried on the card at the point-of-sale. This can be a merchant or other service provider at a retail establishment, or on-line while the user is logged onto a web site, or other location. The information can be swiped by a card reader, or manually entered via a keyboard or other input device. The system supports a wide range of flexibility, permitting issuing systems such as parents and state welfare agencies to restrict the types of authorized uses, and permitting users to access accounts in a prioritized manner. Further, the accepting merchant is not required to be a member because settlement with the merchant may be made via the Federal Reserve Automatic Clearing House (ACH) system by typical and standard electronic transfer. This permits the merchant to take advantage of the lower ACH transaction fees with even greater convenience and flexibility than the current ATM/POS system. The system supports numerous types of identification methods from typical credit card structures with magnetic data strips to various biometric systems such as finger prints, facial recognition and the like. Specifically, once the user is identified, the transaction is managed by his membership data on record with the transaction processing system.
