Speech to text system using controlled vocabulary indices
First Claim
1. An Automated Speech Recognition system for taking dictation wherein the dictation has one or more recognizable contexts, comprising:
- a) means for capturing a first voice input of a dictator at a first time;
b) means for changing the first voice input into a first sound file;
c) means for comparing the first sound file to a first vocabulary list to make text;
d) means for analyzing the text to predict a context of the text;
e) means for selecting a second vocabulary list of refined word choice from the first vocabulary list based on the context of the text;
f) means for capturing a second voice input of a dictator at a second time;
g) means for changing the second voice input into a second sound file; and
h) means for comparing the second sound file to the second vocabulary list to make text.

Abstract
A synthesis of automated speech recognition (voice to text) technology and a knowledge-based analysis of the concepts and contexts of the free text therefrom enable a directed-vocabulary look up index to be used in conjunction with the speech recognition technology thus enabling medical dictation to be transcribed in real time without elaborate training of the dictator or the speech recognition technology. Thus, caregivers can create and review Computer-Based Patient Records in the necessary timeframe consistent with good patient care. The Computer-Based Patient Records can be linked to other applications such as prescription cross checking, lab test results, payer regulations, etc.
