Abstract

Method and its corresponding apparatus for the mechanical recognition of spoken expressions, characterized by the apparatus comprising: a microphone intended to convert spoken expressions into audio signals, filtering means that respond to said audio signals to divide them into n bands, means to define a vocal path that constitutes a series of points with respect to fractions of time in the duration of each audio signal, said points being defined by coordinates, each one representing the respective energy levels of a corresponding energy band, thus located in an n-dimensional space, means to label each point of the path by means of the labels of the reference points preassigned in said space, thus generating a row of labels representative of each pronunciation, means for storing and generating rows of pre-assigned labels for a vocabulary of stored pronunciations, and means for comparing said generated rows of labels with the stored rows of labels in order to identify such spoken expressions.
