The TMS1000 chip inside the original Speak & Spell synthesized voices on the fly both out of novelty and because of storage limitations from 1978-era technology -- it could only handle roughly 200 words. Basic Fun's model won't have those limitations, of course, but that also means the voice is different. It's using recorded dialog processed to sound like it's synthesized, instead of generating sounds on the spot. It's still true to the spirit of the original and offers on-device instructions that weren't an option decades ago, but you'll notice the difference.

As it stands, you might be willing to forgive the break with tradition given the cost. The rejuvenated Speak & Spell will sell for $25 when it arrives in the fall, or low enough that you might prefer this oy over a tablet your kids are more likely to break. We're just hoping there's a Speak & Math follow-up.
