Morphology

subvocal = vocal (semi-transparent) = sub + vocal

Components are clear, but the sense referring to very slight, often instrument-detected articulatory signals is technical and not fully predictable from the parts alone.

Etymology

Subvocal comes from sub- 'under' and vocal 'voice'. Think of it as an 'under the voice' signal — very tiny mouth or throat movements that do not make sound but that machines can detect, which is why subvocal describes those slight speech signals.
