Abstract
Speech recognition is improved by adaptive update of reference word codes. The apparatus can be used for controlling a piece of equipment and comprises memories which in coded form contains the references of the vocabulary of the machine; a microphone, a coding circuit and a memory for coding and memorizing the word pronounced by the user; a device for displaying the word recognized by the apparatus; and a control circuit for comparing the pronounced word to the different memorized references and for displaying at each repetition of the word the words corresponding to the references in their order of resemblance to the pronounced word. The user is able to train the apparatus easily by repeating a word until the displayed word agrees with what he has said, the coded form of this spoken word then being stored as the reference for the corresponding word of the vocabulary.
