Abstract: A method and apparatus for authenticating a proffered identity of a speaker in which the verbal information content of a speaker's utterance, rather than the vocal characteristics of the speaker, are used to identify or verify the identity of a speaker. Specifically, features of a speech utterance spoken by a speaker are compared with at least one sequence of speaker-independent speech models, where one of these sequences of speech models corresponds to speech reflecting information associated with an individual having said proffered identity. Then, a confidence level that the speech utterance in fact reflects the information associated with the individual having said proffered identity is determined based on said comparison. In accordance with one illustrative embodiment, the proffered identity is an identity claimed by the speaker, and the claimed identity is verified based upon the determined confidence level. In accordance with another illustrative embodiment, each of a plurality of proffered identities is checked in turn to identify the speaker as being a particular one of a corresponding plurality of individuals. The features of the speech utterance may comprise cepstral (i.e., frequency) domain data, and the speaker-independent speech models may comprise Hidden Markov Models of individual phonemes. Since speaker-independent models are employed, the need for each system user to perform an individual training session is eliminated.

Granted: 2008-06-17
Abstract: The invention relates to a process for producing by electronic means a model for automatically inspecting the print quality on deformable objects. The model is firstly produced by capturing with an electronic camera (CCD for example) the images of a set of sheets whose print quality is regarded as acceptable; the images are stored so as to produce a first reference image, together with the relevant densitometric tolerance limits. This reference image is thereafter divided into a multitude of sub-images by superimposing a grid with very small mesh cells. During inspection, the distances between the nodes of the grid are measured on the image to be inspected: this therefore produces an elastic modification of the model, which is such as to make the distances between the nodes the same as in the image to be inspected. The image to be inspected is thus verified with respect to the modified reference (model) by using any of the standard inspection techniques.
