How do deaf (since birth) people subvocalize?



Studies have suggested that some do, some don't. The more deaf you are, the less likely you are to subvocalise.

Totally not an expert in this area, but I think everybody associates more than just the sound of the word - movement of lips, memories, and other senses are also involved. Deaf people can obviously acquire those 'subvocalisations' instead.

Sub vocalizing is the fact or reading syllables instead of entire words at once.

Deaf could find very useful to vocalize words as they could read peoples lips and faces based on those units.

Everybody read lips and faces subconsciously, there are famous illusions in witch people hear different sounds with the same sound file depending of the video of a mouth they watch:
