Abstract

974,850. Speech recognition. STANDARD TELEPHONES & CABLES Ltd. June 12, 1963, No. 23397/63. Heading G4R. In a speech recognition system each recognition signal is adapted to send back to the speaker a spoken indication of the word recognised. The microphone 1, Fig. 1 and the speaker 2 may be parts of a telephone hand-set. The microphone signal 5 passes to the recognition circuit 3 and a recognition output 6 causes the corresponding word, recorded e.g. on a magnetic drum in unit 4, to be returned on line 8 to the ear-piece. The recognition signal may also be stored and passed on to further apparatus under the control of the operator if the word returned is correct. The recognition circuit 3 consists of a bank of parallel filters dividing the signal with frequency bands and a timing circuit using the beginning and ending of words and pauses between syllables to derive timing pulses. A further circuit receiving the outputs of the frequency filters and the timing pulses recognises word elements and a recognition circuit compares the resulting combination of word elements with stored combinations to recognise the word. The apparatus also serves to train operators to speak the words in a manner suitable for machine recognition.
