Kurzer Ausflug: Der TI 99/4 A von Texas Instruments war ein Heimcomputer der 1980 auf den Markt kam. Für diesen gab es als Zubehör ein Speech Module. Die Entwickler dieser Speechbox als auch des legendären "Speak and Spell" Lernspielzeugs von Texas Instruments haben später den Sprachchip (Toshiba T6721A) des Magic Voice Moduls für den C64 entwickelt. Daran beteiligt war unter anderem Richard H. Wiggins, Jr.. Toshiba baute übrigens einige Chips für die Taschenrechner von Texas Instruments.

Document: US Patent Number 4209844
Title: Lattice filter for waveform or speech synthesis circuits using digital logic
Abstract: A digital filter of the type which may be used in circuits for generating complex waveforms, such as human speech. The filter has a multiplier, an adder coupled to the output of the multiplier and various delay circuits coupled to the output of the adder. A latch memory is coupled to the output of one of the delay circuits. Switching circuits are provided for the output of the delay and the latch memory to inputs of the multiplier and the adder to selected times. Coefficients of the filter are preferably stored in a memory coupled to another input of the multiplier. The excitation signal is coupled to the adder in one embodiment and to the multiplier in another embodiment. In either embodiment, the digital filter may be implemented on a single integrated circuit chip.

Document: US Patent Number 4970659
Title: Learning aid or game having miniature electronic speech synthesis chip
Abstract: An electronic hand-held, talking learning aid is disclosed. The learning aid includes a MOS speech synthesizer chip having an active surface area on the order of 45,000 square mils. The disclosed speech synthesizer chip includes a digital lattice filter, a voiced/unvoiced excitation circuit, a speech parameter interpolator, an input parameter decoder, a digital-to-analog converter and associated timing circuits. The learning aid is also provided with a microprocessor which functions as a controller for controlling the operation of the unit. A small speaker is driven by the digital-to-analog converter on the speech synthesis chip and a keyboard and display device are strobed by the microprocessor controller. Features include modes in which a speech synthesizer recites instructions or questions to the operator who must properly respond.

Title: C²MOS speech synthesis systems
Authors: Fuminari Tanaka, Hiroshi Shigehara, Hiroaki Suzuki, Yasoji Suzuki, Ichizoh Takimoto
Toshiba Corporation, Kawasaki, Japan
Abstract: Employing an updated C²MOS technique, two types of speech synthesizer LSI circuits, based on the PARCOR and the ADM methods, are introduced and described.
These two LSI circuits, fabricated with a standard metal gate CMOS process, have several features.
1) They can be operated with a single power supply over a 3-7 V range.
2) Their power dissipations are, respectively, 0.6 mW (PARCOR) and 0.18 mW (ADM) with the supply at 3 V.
3) High accuracy 9- and 10-bit R, 2R D/A converters are constructed in each LSI circuit.
In the PARCOR system, various high quality and low data rate speech outputs are obtainable. The ADM system is used for voice transmission and synthesis. By adequately applying these two systems to the wide needs in the market, it is possible to achieve good cost performance.
