I believe Ford too incorporated his consciousness to the hosts' programming.

NO

It's clear that the voices that Delores hears are programmed in the attempt by Ford to give the hosts sentience...and eventually Delores' mind starts an internal dialogue.

The key to Dolores' achieved sentience lies in the Bicameral mind theory — a theory Arnold used to "bootstrap" consciousness. He programmed Dolores and the other hosts to hear "the voice of God" in their head, and his hope was that their own internal thoughts would eventually take over.

..

Dolores hasn't been guided by the ghost of Arnold or by some of Ford's new narrative code. The whole time she was truly hearing her own thoughts, her own voice. There wasn't a second host version of herself or anything like that, but she was having visions of herself as a manifestation of her developing consciousness.
