  • Speech recognition with sequence parsing, rejection and pause detection options
    Patent number: 5848388
    Abstract: A recognition system includes a speech recognition processing unit for processing input speech signals to indicate similarity to predetermined patterns to be recognized. The recognition processing unit is arranged to repeatedly partition the input speech signal into a pattern-containing portion and, preceding and following the pattern-containing portions, noise or silence portions, and to identify a pattern corresponding to the pattern containing portion. An output supplies a recognition signal indicating recognition of one of the patterns. A pause detector detects the noise or silence portion which follows the pattern-containing portion. In response to its detection, a signal identifying the pattern currently corresponding to the pattern portion is supplied to the output. Also provided are similarly operating rejection portions.
