Title: A speech recognition system
Inventor: STRONG ROBERT DON
IPC: G10L15/193
Filed: 1993-12-29
Granted: 2005-02-15
Abstract: Maintaining dynamic categories for speech rules in a speech recognition system which has a plurality of speech rules each comprising a language model and action. Each speech rule indicates whether the language model includes a flag identifying whether the words in the language model is dynamic according to changing data in the speech recognition system. At periodic intervals, such as system initialization or application program launch time, for each flag in each speech rule which indicates that words in the language model an dynamic, the words of each of the language model(s) are updated depending upon the state of the system. Concurrent with the determination of acoustic features during speech recognition, a current language model can be created based upon the language models from these speech rules. Also, speech rules are partitioned according to the context in which they an active. When speech is detected, concurrent with acoustic feature extraction, the current state of the computer system is used to determine which rules are active and how they are to be combined in order to generate a language model for word recognition. Also, partitioning speech recognition rules for generation of a currant language model and interpretation in a speech recognition system is described. Rapid and efficient generation of a language model upon the detection of a current context at a second interval (e.g. upon the detection of speech in one embodiment) then may be performed.

Abstract: Anhydrous milk powder is prepared to have substantially the same constituent ingredients as dry whole milk powder that is manufactured using conventional processes, except that 100% of the fat constituent is available as fat. Whole milk is first separated into skim milk and anhydrous butter fat; the skim milk is dried by removing all of the available free water therefrom; and the resultant anhydrous skim milk powder solids are combined in a selected amount together with a further selected amount of the separated anhydrous butter fat constituent in a ribbon blender. The resultant blended product has the same constituent make-up as ordinary dry whole milk, but all of the fat constituent is recoverable as fat. The anhydrous milk powder of the present invention is intended primarily for use by the chocolate industry, in the manufacture of milk chocolate, but may also be utilized for other purposes such as the manufacture of dry baking mixes, or other prepared foods, where the dry whole milk powder is not to be rehydrated. The apparatus includes means for extracting anhydrous butter fat constituent from unhomogenized whole milk, means for drying the resultant skim milk, and a ribbon blender equipped with spray nozzles to re-blend the anhydrous butter fat with the dried skim milk. The precise amount of available fat constituent in the resultant anhydrous whole milk powder can be closely defined and obtained. In certain cases, a portion of the anhydrous fat that is added back to the dried skim milk may be a compatible vegetable oil.
