ABSTRACT:
Upon analyzing grammatically and phonetically a printed text for accents, pauses, intonations and influences of adjacent voice elements in a sentence to be synthesized, a computer loads a plurality of registers including an address counter with instructions for addressing a read-only memory, these instructions specifying rates of counting, numbers or counts, whether counting is to be decremental or incremental and initial addresses of sequences of binary bits coding successive magnitudes of noise signals or of voice-frequency functions. The output of the read-only memory is fed to a loudspeaker via a digital/analog converter and an amplifier whose output is modulated by a signal transmitted from the computer through another d/a converter. The durations of noise and voice-frequency speech elements read out from the memory and the modulation of their amplitudes by the amplifier are randomly modified within .+-.3% for the frequency and .+-.30% for the amplitude by the computer to obtain natural-sounding speech from the loudspeaker, while smooth transitions between phonemes or voice elements are attained via the insertion of noise or voice-frequency elements ensuring an even formant or frequency distribution.
