摘要：A speech synthesis system comprising voiced/unvoiced excitation means forgenerating voiced/unvoiced excitation signals. Filter means are provided for convertingexcitation signals into digital signals representative of human speech. Converter meansare coupled to said filter means for converting said digital signals representative of

human speech into analog signals. Audio means are coupled to said converter means forconverting said analog signals into audible sound. External excitation input means areprovided for receiving externally generated excitation signals, and control means areoperably coupled to said voiced/unvoiced excitation means and said external excitationinput means for selectively coupling either said voicedunvoiced excitation means or saidexternal excitation input means to said filter means in response to a control signal. Thespeech synthesis system may be constructed by employing meta-insulator-semiconductor technology so as to provide circuits capatable of low voltage operation.
