Stenographic translation system automatic speech recognition
First Claim
1. A stenographic translation system, comprising:
- (a) a stenographic processor device for converting lexical stroke symbols to a first output having a time value, said first output comprising units of (i) language text words and (ii) sets of undefined lexical stroke symbols,(b) a speech recognition system for converting utterance to a second output having a time value, said second output comprising units of (i) language text words and (ii) textual symbols to indicate undefined utterances,(c) means for matching units of said first output with corresponding units of said second output within a time window to provide paired units, and(d) outputting means for processing said paired units for outputting from each paired unit a unit selected from the group consisting of language text words and sets of undefined lexical stroke symbols.

Abstract
The present invention involves a stenographic translation system which comprises (a) a stenographic processor device for converting lexical stroke symbols to first output units comprising language text words and sets of undefined lexical stroke symbols; (b) a speech recognition system using clusters of speech word models of a vocabulary to define word output units from speech, the units each having a system clock time value; (c) an output controller for outputting defined words by matching the output units within a time window and selecting a final output word or undefined symbol. A method is provided wherein a human speaker makes an utterance which is received essentially simultaneously by a stenographer and a speech recognition system. The stenographer manually applies first inputs to keys in a stenographic processor device to generate first outputs by using a scan chart with translations to define a word output from the stenographic processor. The speech recognition system converts the utterances to a second output. The controller processes the outputs to provide words. The system permits updating of vocabulary dictionaries of the system.

6. A method for providing a stenographic translation of utterances, said method comprising:
-
(a) providing stenographic key strokes corresponding to said utterances, (b) translating said strokes into first units comprising words in language text format and undefined lexical stroke sets, (c) providing word models corresponding to said utterances, (d) translating said word models into second units comprising words in language text formats an textual symbols to indicate undefined utterances, (e) matching said first units with said second units to provide pairs of corresponding units, (f) outputting a word from each pair comprising a word. - View Dependent Claims (7, 8)
