The phone was from the 80's: it is possible the voice recognition was a single chip solution from TI - they did other specialised ICs. If so multiple devices could have the same voice recognition. Or maybe a firmware solution for a TI processor? I did a quick search, but finding data sheets from the 80's without knowing the part number is difficult. I tried to find a schematic for the FV-1000 but no luck there either.
