deafdyke - Firstly CS is not basically Visual Phonics.
For example, cueing with an infant: all the phonemes are received visually and depending on the level of hearing loss auditorally.
Let me provide for you the linguistic definition of phoneme, from: phoneme - Definitions from Dictionary.com

pho·neme/ Pronunciation Key - Show Spelled Pronunciation[foh-neem] Pronunciation Key - Show IPA Pronunciation –noun Linguistics.
any of a small set of units, usually about 20 to 60 in number, and different for each language, considered to be the basic distinctive units of speech sound by which morphemes, words, and sentences are represented. They are arrived at for any given language by determining which differences in sound function to indicate a difference in meaning, so that in English the difference in sound and meaning between pit and bit is taken to indicate the existence of different labial phonemes, while the difference in sound between the unaspirated p of spun and the aspirated p of pun, since it is never the only distinguishing feature between two different words, is not taken as ground for setting up two different p phonemes in English.
The person who is cueing provides the phonemes of spoken language, (using English as the example through out this post), as a stream of sound rhythmically, using the syntax and grammar of English.
For example:
"Are you enjoying you weather today?"
I would cue to you the phonemes of those exact words in that exact order, even raising my eyebrows. Cueing is done with prosody (stress and intonation) and expression.
I am not a neuroscientist and cannot explain to you the precise pathways or science involved, BUT, for a person who is profoundly deaf and they are receiving phonemes of English via CS, in conjunction with the mouth shapes, this information is processed in the auditory "cortex" of the brain. People who are deaf, and have been raised consistently with an accurate model of phoneme cues for communication, language and literacy develop "inner voices". This has been described to me, (in discussion with adults, with profound hearing loss, who have used cueing as their primary familial communication) when asked for clarification of what exactly this means for them, simply as "hearing the words”. I find this absolutely amazing!
Does this explanation answer you question:
