There are two major families of K-2-8, the Votrax SC01A based unit which uses TMS roms for text/question data (you dumped these kevtris):

CM62050 1981 Tiger Electronics K-2-8 model 7-230 1/2 16KiB 4bit (inv. CE) Non-TI Speech Chip Yes 6AFB8645
CM62051 1981 Tiger Electronics K-2-8 model 7-230 2/2 16KiB 4bit (inv. CE) Non-TI Speech Chip Yes 0FA61BAA

And The Tiger Electronics K-2-8 model 7-232, which was also OEM'ed to Coleco as the Talking teacher, AND to SEARS as the Talkatron.
These later ones are TMS5110 based, and uses onboard and cartridge VSM's for LPC data. (I wand to make a blog post of the 4 variants at one point)
