A quick regexp search "\(..\)\1" revealed a sequence of four $e6 $d1. Other repeating two-byte sequences were probably data. I also searched for three-byte sequences: $06 $ee $84 repeats six times. I don't have a disassembler at hand, but this should be helpful to anyone who wants to investigate further. > It's possible the two writes to $FD20 in the final TED kernal are this > sort of thing, but I've not been able to disassemble the speech .bin > file.

In the beginning, it has two times jmp $839d (yes, that was also found by my regexp search). This suggests that the starting address is $8000. Prepend the bytes $00 $80 to the file, and load it as a normal program to $8000-$bfff. Marko - This message was sent through the cbm-hackers mailing list.
