When you think you silently speak.
‘Speak Thinking’ is the recording of that process.
If you can record this silent speech then you can record your thinking.
Speak thinking is not dependent on the electrical activity of your muscles  to record thinking but rather on the flow of air in your thoracic cavity that is created because of breathing.  The constant air flow in and out because of breathing is modulated by your vocal cords in silent speaking when you think and it is the recording of this modulation that creates ‘speak thinking’.
Think strongly numbers 1 to 20 and pick a number in your mind.
speak thinking numbers 1-20/14

Think of the name of the singer (clue: it is not about the money).
Subvocal: reading
As technology get more adventurous algorithms could be written to better interpret these “speak thinking” recordings and more sensitive recording devices used to listen in to the thinking process – as you silently speak when you think. The thinking is modulated in your breath as you breath in and out.  This is only an external manifestation of what happens silently 24/7 between us as we communicate all the time with each other subliminally, and I think this is what the ancients meant by the human race is united as 1, Manchester United subliminal.
