Abstract
The method consists in analyzing phonemes of the phonetic signal at regular intervals of time, comparing the phonemes with a series of reference phonemes, selecting the reference phoneme closest to the phoneme of the phonetic signal and generating a visible indication of the selected phoneme in real time on a monitor (20) to allow the speaker to adapt his speech to the response of the apparatus. The apparatus comprises a series of analyzers (A.sub.1, A.sub.2 . . . A.sub.n) for a phonetic signal segment for generating a series of vectors (V) to be compared by a set (13) of comparators (C.sub.1, C.sub.2 . . . C.sub.m) with a plurality of reference vectors corresponding to the various reference phonemes. A control unit (19) receiving the result of the comparison controls the visual display on the monitor (20) of a histogram indicating the selected phoneme and also a merit value (P) and a stability value (ST), of the recognition. A lexical recognition unit (22) is adapted to link individual phonemes together to recognize words and to display the words on the monitor (20).
