A bio-signal related to the impedance between two points 34, 36 on a speaker's skin 32 is monitored while a speech recognition system is trained to recognize a word or utterance. An utterance is identified for retraining when the bio-signal is above an upper threshold or below a lower threshold while the recognition system is being trained to recognize the utterance. The recognition system is retrained to recognize the utterance when the bio-signal is between the upper and lower thresholds. (FIG. 2)

Un signal biologique, relié à l'impédance entre deux points (34, 36) sur la peau d'une personne qui parle (32), est contrôlé pendant que le système de reconnaissance de la parole est éduqué de façon à reconnaître un mot ou un énoncé. Un énoncé est identifié pour la rééducation lorsque le signal biologique est plus élevé qu'un seuil supérieur ou plus fiable qu'un seuil inférieur, pendant que le système de reconnaissance de la parole est éduqué afin de reconnaître l'énoncé. Le système de reconnaissance de la parole est alors rééduqué pour reconnaître l'énoncé lorsque le signal biologique se trouve entre les seuils supérieur et inférieur. (FIG. 2)
