Yes, it uses digitised speech, so you're limited to the words and word
parts that are addressable in the ROMs. There were two standard ROMs in
the kits, and a few others available at one time. I assume there was
information on how to digitise your own, but I've never seen it. It was
quite good quality, though.
The Texas TMS5200NL was a bit more versatile in that it was possible to
provide your own data, but I don't think it was easy. It normally used
special serial ROMs. Better quality; you could actually make it sing.

The SP0256 sounds very robotic compared to the NS and Texas devices.
The SC-01 is reputedly better (variable pitch, for one thing) but I've
not got much experience of either. I've not used any of the more modern
chips, but there are a few out there.
