| Number | Title | Issue Date |
| 4470150 | Voice synthesizer with automatic pitch and speech rate modulation Understandability of synthesized speech is improved by random modulation: after a predetermined number of phonemes, the speech rate is changed by a random amount, with proportional changes in pitch and phoneme transition rate.... | 09/04/1984 |
| 4433210 | Integrated circuit phoneme-based speech synthesizer A phoneme-based speech synthesizer that is particularly adapted for implementation on a single integrated circuit chip. The vocal tract is comprised of a fixed resonant filter and a plurality of tunable resonant filters whose resonant frequencies are cont... | 02/21/1984 |
| 4422196 | Method of forming a torque nut A prevailing type torque nut, and method and apparatus for manufacturing such a nut. The nut is formed with two locally deformed locking portions which are formed in such a way that the remainder of the threads extending between the locking portions is su... | 12/27/1983 |
| 4419657 | Speech digitization system A speech digitization system including novel encoder and decoder circuits that minimizes the number of resolution bits required to produce a given level of speech quality by optimizing the information content of the digital output signal from the encoder.... | 12/06/1983 |
| 4301328 | Voice synthesizer A voice synthesizer that is responsive to sequences of digital input command words to phonetically synthesize human speech. The system includes control circuits that are responsive to the input command words to introduce an articulated silent phoneme into... | 11/17/1981 |
| 4264783 | Digital speech synthesizer having an analog delay line vocal tract A phoneme based speed synthesizer that utilizes an analog delay line (ADL) vocal tract which simulates the variations in the acoustical characteristics of the human vocal tract which occur as a result of changes in the cross-sectional area of the human vo... | 04/28/1981 |
| 4215240 | Portable voice system for the verbally handicapped A completely self-contained, battery operated, portable voice system for the verbally handicapped which is sufficiently compact to be hand held.
