Patent number: 8285537Abstract: Recognition of proper nouns by an automated speech recognition system is improved by augmenting the pronunciation of each proper noun or name in the natural language of the speech recognition system with at least one “native” pronunciation in another natural language. To maximize recognition, preferably the pronunciations are predicted based on information not available to the speech recognition system. Prediction of pronunciation may be based on a location derived from a telephone number or postal address associated with the name and the language or dialect spoken in the country or region of that location. The “native” pronunciation(s) may be added to a dictionary of the speech recognition system or directly to the grammar used for recognizing speech.Type: GrantFiled: January 31, 2003Date of Patent: October 9, 2012Assignee: Comverse, Inc.Inventors: Marc D.

Patent number: 8271278Abstract: A system, method and computer program product for classification of an analog electrical signal using statistical models of training data. A technique is described to quantize the analog electrical signal in a manner which maximizes the compression of the signal while simultaneously minimizing the diminution in the ability to classify the compressed signal. These goals are achieved by utilizing a quantizer designed to minimize the loss in a power of the log-likelihood ratio. A further technique is described to enhance the quantization process by optimally allocating a number of bits for each dimension of the quantized feature vector subject to a maximum number of bits available across all dimensions.Type: GrantFiled: April 3, 2010Date of Patent: September 18, 2012Assignee: International Business Machines CorporationInventors: Upendra V.

Patent number: 8265932Abstract: A system and method for identifying audio command prompts for use in a voice response environment is provided. A signature is generated for audio samples each having preceding audio, reference phrase audio, and trailing audio segments. The trailing segment is removed and each of the preceding and reference phrase segments are divided into buffers. The buffers are transformed into discrete fourier transform buffers. One of the discrete fourier transform buffers from the reference phrase segment that is dissimilar to each of the discrete fourier transform buffers from the preceding segment is selected as the signature. Audio command prompts are processed to generate a discrete fourier transform. Each discrete fourier transform for the audio command prompts is compared with each of the signatures and a correlation value is determined. One such audio command prompt matches one such signature when the correlation value for that audio command prompt satisfies a threshold.Type: GrantFiled: October 3, 2011Date of Patent: September 11, 2012Assignee: Intellisist, Inc.Inventor: Martin R.

Patent number: 7945444Abstract: In detection systems, such as speaker verification systems, for a given operating point range, with an associated detection “cost”, the detection cost is preferably reduced by essentially trading off the system error in the area of interest with areas essentially “outside” that interest. Among the advantages achieved thereby are higher optimization gain and better generalization. From a measurable Detection Error Tradeoff (DET) curve of the given detection system, a criterion is preferably derived, such that its minimization provably leads to detection cost reduction in the area of interest. The criterion allows for selective access to the slope and offset of the DET curve (a line in case of normally distributed detection scores, a curve approximated by mixture of Gaussians in case of other distributions). By modifying the slope of the DET curve, the behavior of the detection system is changed favorably with respect to the given area of interest.Type: GrantFiled: September 8, 2008Date of Patent: May 17, 2011Assignee: Nuance Communications, Inc.Inventors: Jiri Navratil, Ganesh N.

Patent number: 7917365Abstract: Exemplary methods, systems, and products are disclosed for synchronizing visual and speech events in a multimodal application, including receiving from a user speech; determining a semantic interpretation of the speech; calling a global application update handler; identifying, by the global application update handler, an additional processing function in dependence upon the semantic interpretation; and executing the additional function. Typical embodiments may include updating a visual element after executing the additional function. Typical embodiments may include updating a voice form after executing the additional function. Typical embodiments also may include updating a state table after updating the voice form. Typical embodiments also may include restarting the voice form after executing the additional function.Type: GrantFiled: June 16, 2005Date of Patent: March 29, 2011Assignee: Nuance Communications, Inc.Inventors: Charles W. Cross, Jr., Michael C. Hollinger, Igor R. Jablokov, Benjamin D. Lewis, Hilary A. Pike, Daniel M. Smith, David W. Wintermute, Michael A. Zaitzeff

Patent number: 7885818Abstract: An apparatus with a speech control unit includes a microphone array having multiple microphones for receiving respective audio signals, and a beam forming module for extracting a speech signal of a user, from the audio signals. A keyword recognition system recognizes a predetermined keyword that is spoken by the user and which is represented by a particular audio signal and is arranged to control the beam forming module, on basis of tie recognition. A speech recognition unit creates an instruction for the apparatus based on recognized speech items of the speech signal. As a consequence, the speech control unit is more selective for those parts of the audio signals for speech recognition which correspond to speech items spoken by the user.Type: GrantFiled: September 22, 2003Date of Patent: February 8, 2011Assignee: Koninklijke Philips Electronics N.V.Inventor: Fabio Vignoli
