The VecVox is a SpeakJet based unlimited-vocabulary speech / sound synthesizer

connecting to the Vectrex console via the second joystick port

My on-board VecTrans™ chip accurately emulates the old SPO256-AL2 based VecVoice

making the unit fully compatible with the existing speech games -

(VecVoice is activated by holding down the mode switch on power-up)

In normal (SpeakJet) mode, the unit is capable of amazing retro speech and sound effects -
