Add voice control to your PC. Part 2. Building the speech output module. Est. cost: $90. Speech board makes anything talk. Synthesizer may be used alone or with virtually any computer. Est. cost: $150. How to interface the Texas Instrument "SPEAK & SPELL" learing device to a Sinclair or Timex computer. Computer-controlled stored-word speech synthesizer is driven by the parallel printer port. Est. cost: $75. Experiments in voice recognition. (1) Stand-alone circuit will recognize eight words and short phrases from almost any speaker, and light a corresponding LED in response. (2) Stand-alone circuit uses eight vocal inputs to control a motorized model car or other project. Computer-controlled voice synthesizer (speech processor) can be programmed to prompt the computer user and/or to provide audio feedback. How to attach a speech processor to the Radio Shack Color Computer. Some tips. Computer speech synthesizer receives standard ASCII code (via RS-232 port) and converts it into spoken words. Short program for the Apple II computer will produce a gross approximation of a human voice through its built-in speaker. The "words" are those actually recorded on a cassette and decoded by the computer. How to record a vocal response on a tape recorder connected to a computer, and then play back the voice under program control at appropriate places in the program to give the illusion that the computer is talking. Application to a TRS-80 is described. Two intriguing and useful Apple II peripherals. (1) Heuristics Speechlab. (2) Mountain Hardware Apple Clock. Includes program and use suggestions. Speech synthesis for the SWTP computer. Tips on interfacing and using the Votrax synthesizer (originally designed to interface to the TRS-80 computer). Advances in speech synthesis. Includes the codes for the "Digitalker" IC vocabulary, a TRS-80 hardware interface schematic, etc. Computer control of a Texas Instrument "Speak & Spell" toy. Uses an interface from Percom Data Company. Includes a 6502 machine-language driver and a BASIC driver. A super synthisizer.
