The Echo II is a plug-in expansion card, speech synthesizer card for the Apple II and Apple IIe personal computers that allow applications to use speech synthesis. [1] The Echo II provides a speaker/headphones jack on board, with a physical volume control adjustment.
The Echo II software can synthesize either unlimited text-to-speech using stitched phonemes, or play back raw LPC data for specific words, with resulting higher speech quality.
LPC ( linear predictive coding) is the speech synthesis technology used, which allowed applications to encode speech data in a compact form. The Echo II uses the TMS 5220 LPC Speech Chip which was popular in other speech synthesizers.
