Abstract: A method for processing diamonds and corresponding ornamental diamond structures employ diamonds having visible cloud inclusions. The diamond is cut and polished to form crown and pavilion facets angled so as to form a light transmission window over a readily noticeable portion of an area of the diamond. This renders a geometrical form of the cloud inclusion readily visible to the unaided human eye. Preferably, a major part of the light transmission window is formed by a primary table facet of the crown and a primary base facet of the pavilion angled which are roughly parallel to each other.

Abstract: A speech recognition system comprising: an analog to digital converter, a time to frequency transformer, a noise filter; a context preprocessor, an acoustic word classifier, an initial acoustic model generator, a textual search module, and a trainer. The system recognizes speech initially prior to training, due to the context preprocessor classifying words of identical sound by the context of a leading and trailing neighboring group of words and by the acoustic model generator creating an initial acoustic model derived from an acoustic word statistical analysis ‘average’. Applications of the system include voice activated computer games, command and control systems and text dictation.
