Street Electronics Echo Speech Synthesizer PC2 - Vintage Voice Synthesizer?

Anyone know more about this one? I don't believe I've ever seen one of these before. The listing doesn't state much: "Up for sale or best offer is one Vintage Street Electronics Echo PC2 Synthesizer!

No card was included in the box, however it includes the external speaker box unit,manual,
and two larger floppy discs."

According to one of the floppies the brand is Street Electronics CORP. and the copyright date is 1988.

Update via Dave O Mahony in the comments: "Looks like the Echo 2 speech sound card add on for the Apple II. Seems it used the same chip as the Speak & Spell! [link] Auction doesn't include the card - just software and speaker!"

via Wikipedia:

"The Echo II was a plug-in expansion card, speech synthesizer card for the Apple II and Apple IIc personal computers that allowed applications to use speech synthesis. The Echo II used the TMS5220 speech synthesis chip to synthesize speech. The Echo II software could 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) was the speech synthesis technology used, which allowed applications to encode speech data in a compact form. The Echo II used the TMS 5220 LPC Speech Chip which was popular in other speech synthesizers"
