• SpeakJet is a single-chip sound synthesizer consisting of 72 speech elements (allotments), 43 sound effects, and 12 DTMF touchtones.
• By selecting these sounds and controlling pitch, rate, bend, and volume parameters, you can generate unlimited phrases and sound effects with thousands of variations.
• Logic changes on any one of the eight event input lines can be simultaneously controlled by a single I/O serial line, allowing both CPU control and standalone operations.
