The Echo 2 was a speech synthesizer card for the Apple 2 and Apple //c personal computers. The Echo 2 used the TMS5220 speech synthesis chip, which could accept either phonemes or raw LPC data, with resulting higher speech quality.
The Echo 2 was a plug-in expansion card designed for the Apple 2 computer, and allowed applications to use speech synthesis. LPC (linear predictive coding) was the speech synthesis technology used, which allowed applications to encode speech data in a compact form. The Echo 2 used the TMS 5220 LPC Speech Chip which was popular in other speech synthesizers
