Abstract: Method of order assembly, including the following steps: a plurality of orders each including a plurality of articles are displayed successively or simultaneously on an assembly screen; team member from among a plurality of team members says the order on which he will work (“prepare orange order”), reads article identifications on the assembly screen, will pick the physical article or articles corresponding to these identifications and verbally designates these articles by means of voice commands; the designation of orders and of articles indicated by the team member as well as various commands said by the team member during the method of assembly are recognized by means of a voice recognition system; the order concerned is updated on the assembly screen so as to indicate that the article or articles has or have been picked.

Abstract: A portable voice capture device having an orientable arm comprising a first leg and a second leg, the first leg and the second leg having different orientations, the first leg of the first arm comprising a first differential linear array of microphones, a directivity of the first differential linear array being arranged for improved sensing of voice from a user, the second leg of the arm comprising a second differential linear array of microphones, a directivity of the second differential linear array being arranged for improved sensing of noise from a different than the direction of said sensed voice, and a noise reduction circuit for providing a voice signal with reduced noise, based on the output of the first array and on the output of the second array.

Abstract: An automatic speech recognition system for recognizing a user voice command in noisy environment, including: matching means for matching elements retrieved from speech units forming said command with templates in a template library; characterized by processing means including a MultiLayer Perceptron for computing posterior templates (P(Otemplate(q))) stored as said templates in said template library; means for retrieving posterior vectors (P(Otest(q))) from said speech units, said posterior vectors being used as said elements. The present invention relates also to a method for recognizing a user voice command in noisy environments.

Abstract: A portable voice capture device comprising: an orientable arm with a first differential array of microphones comprising at least one pair of microphones, the directivity of said first array being arranged for sensing voice from a first direction depending on the orientation of said arm; a second differential array of microphones comprising at least one pair of microphones, the directivity of said second array being arranged for sensing noise from a second direction different from the first direction; a noise reduction circuit for providing a voice signal with reduced noise, based on the output of said first array and on the output of said second array.
