  • Speech recognition incorporating a priori probability weighting factors
    Patent number: 5999902
    Abstract: A recognizer is provided with a priori probability values (e.g., from some previous recognition) indicating how likely the various words of the recognizer's vocabulary are to occur in the particular context, and recognition "scores" are weighted by these values before a result (or results) is chosen. The recognizer also employs "pruning" whereby low-scoring partial results are discarded, so as to speed the recognition process. To avoid premature pruning of the more likely words, probability values are applied before the pruning decisions are made. A method of applying these probability values is described.
