CA 2158849

A recognition system comprising: input means for receiving a speech signal; recognition processing means for processing the speech signal to indicate its similarity to predetermined patterns to be recognised, said recognition processing means being arranged repeatedly to partition the speech signal into a pattern-containing portion and, preceding and following said pattern-containing portions, noise or silence portions, and to identify a pattern corresponding to said pattern containing portion; and output means for supplying a recognition signal indicating recognition of one of said patterns, characterised by pause detection means for detecting the noise or silence portion which follows the pattern-containing portion, and means, responsive to the detection thereof, arranged to supply a signal identifying the pattern currently corresponding to the pattern portion to the output means. Also provided are similarly operating rejection means.

Système de reconnaissance comprenant: des moyens d'entrée servant à recevoir un signal vocal; des moyens de traitement de reconnaissance servant à traiter le signal vocal, afin d'indiquer sa similitude à des configurations prédéterminées à identifier, lesdits moyens de traitement de reconnaissance étant conçus de façon répétée afin de diviser le signal vocal en une partie contenant une configuration et en des parties de bruit ou de silence précédant et suivant lesdites parties contenant des configurations, ainsi que d'identifier une configuration correspondant à ladite partie contenant une configuration; des moyens de sortie servant à émettre un signal de reconnaissance indiquant la reconnaissance d'une desdites configurations, charactérisée par des moyens de détection de pause servant à détecter la partie de bruit ou de silence suivant la partie contenant une configuration, ainsi que des moyens, réagissant à ladite détection, conçus pour émettre un signal identifiant la configuration correspondant normalement à la partie de configuration vers les moyens de sortie. L'invention concerne également des moyens de rejet fonctionnant de façon similaire.
