Claims
- 1. A speech synthesizer circuit, comprising:
- first storage means for storing phoneme data therein;
- second storage means for storing adjustment data and a repetition number therein;
- control means connected to the first and second storage means for retrieving selected ones of said phoneme data from said first storage means and combining the selected phoneme data to produce a first tone of speech waveform, said control means retrieving selected ones of said adjustment data from said second storage means and modifying said first tone of speech waveform utilizing the selected adjustment data from said second storage means to produce a second tone of speech waveform, said second tone of speech waveform being divided into a plurality of frames on the time axis;
- means connected to said control means and responsive to said second tone of speech waveform for producing an audible speech message at a predetermined readout rate, said audible speech message being generated in a predetermined period of time at said predetermined readout rate; and
- readout time control means connected to said control means and responsive to the repetition number stored in said second storage means for causing said control means to selectively vary the number of repetitions of like frames associated with said second tone of speech waveform for producing a modified form of said audible speech message in a time period different from said predetermined time period but at said same readout rate.
- 2. A speech synthesizer circuit in accordance with claim 1, wherein said speed control means comprises:
- further storage means connected to said second storage means for receiving said repetition number from said second storage means and storing said repetition number therein;
- switch means for selecting a desired speed of generation of said audible speech message; and
- multiplier means interconnected between said further storage means and said switch means for sensing the selection made by said switch means, for storing a constant therein corresponding to said selection, and for multiplying said constant by said repetition number stored in said further storage means, producing a resultant repetition number,
- said control means varying the number of each of said frames associated with said second tone of speech waveform in correspondence with said resultant repetition number.
