CA 2340028
The invention concerns a neural net system comprising a plurality of levels (20, 21, 22) of interconnected computing elements (10, 11), said levels comprising an input level (20) whereto a sequence of input speech vectors (2) can be applied at least at a first rate. At least one computing element (10) includes a supervisory classifier (102) to reduce the rate of the delivered signal. A parametering unit enables to deliver said speech vectors (2) from a digital speech signal. The invention enables speech recognition from a set of speech vectors corresponding to a large number of frames of the speech signal.
Système de réseaux neuronaux comprenant une pluralité de niveaux (20, 21, 22) d'éléments de calcul interconnectés (10, 11), lesdits niveaux comprenant un niveau d'entrée (20) auquel une séquence de vecteurs vocaux d'entrée (2) peut être appliquée à au moins une première cadence. Au moins un élément de calcul (10) comporte un décimateur (102) pour réduire la cadence du signal délivré. Un paramétriseur permet de délivrer lesdits vecteurs vocaux (2) à partir d'un signal vocal numérique. Avantages: reconnaissance vocale à partir d'un ensemble de vecteurs vocaux correspondant à un nombre de trames important du signal vocal.
