DT1000 Master Word List Schematic Diagram Timing Waveforms Typical ApplicationGeneral Description (in brief)The DIGITALKER (DT1000) speech synthesis evaluation board is an extremely easy to use device for understanding the operation and application of the DIGITALKER chip set in an end product.The DT1000 contains all components required to output speech upon demand a speech processor chip (SPC) 2 Maxi-ROMs containing 138 individual words linear filter audio amplifier keyboard and COPS microcontroller with stored data programmed to provide the various functions on the board. The only external hardware required for complete operation are a single 7V-11V power supply a speaker of your choice for size and quality and this instruction sheet.The 2 speech MAXI-ROMs employed on the board contain a brief introductory phrase 138 separate and individual words consisting of numbers and letters of the alphabet assorted useful nouns verbs and tones and 5 individual silence durations. (In constructing a phrase different silence durations between different words significantly affect the overall quality of the phrase).A COPS program is provided which permits the user to 1) sequentially output each word automatically 2) repeat any desired word 3) build any store several short phrases for outputting when desired 4) output a canned phrase which permits insertions and changing a word in the phrase 5) play a simple game which requires some interaction between the keyboard and the user and 6) output hex equivalent decimal number inputs.
