The SoundGin is a completely self contained, single chip voice and complex sound synthesizer. It uses a mathematical sound algorithm to control an internal five channel sound synthesizer to generate on-the-fly, unlimited vocabulary speech synthesis and complex sound generation. The SoundGin is programmed with 72 speech elements (allophones), 43 sound effects, and 12 DTMF Touch Tones. Through the selection of these sounds and in combination with the control of the pitch, rate, bend, and volume parameters, the user has the ability to produce unlimited phrases and sound effects, with thousands of variations, at any time. The SpeakJet can be controlled simultaneously by logic changes on any one of its eight Event Input lines, and by a single I/O line from a CPU (such as the OOPic or the Basic Stamp) allowing for both CPU-Controlled and Stand-Alone operations. Other features include an internal 64 byte input buffer, Internal Programmable EEPROM, three programmable outputs, and direct user access to the internal five channel sound synthesizer.
The Soundgin's P.C. Console Software provides a means of experimenting with the sounds that can be produced by the Soundgin. The software generates, displays and sends to the Soundgin all the necessary serial data for the functions found on the console.
