How a divine name is spoken in these rituals: breathed in, drawn down through the body, sent out with the Sign of the Enterer, and closed with the Sign of Silence.
The pentagram ritual says “Say (i.e., vibrate) I H V H”. This is Liber O's account of what vibrating means, from the chapter before the rituals.

Liber O, 1909
The steps
Each step gives the action in plain language, the spoken words with their
Hebrew, and the corresponding line from Liber O in The
Equinox I:2 (1909). The drawings follow those instructions.
The vibration
(a)
Stand with the arms stretched out.
(a) Stand with arms outstretched. (See Illustration.)
When it seems to touch the feet, step forward with the left foot, throw the body forward and shoot the hands out — the Sign of the Enterer — breathing the name out as it rushes up through the body.
(d) The moment that it appears to touch the feet, quickly advance the left foot about twelve inches, throw forward the body, and let the hands (drawn back to the side of the eyes) shoot out, so that you are standing in the typical position of the God Horus, and at the same time imagine the Name as rushing up and through the body, while you breathe it out through the nostrils with the air which has been till then retained in the lungs. All this must be done with all the force of which you are capable.
Liber O's own warning about what these practices are
It is immaterial whether these exist or not. By doing certain things certain results will follow; students are most earnestly warned against attributing objective reality or philosophic validity to any of them.
How Liber O says to tell that a vibration was done rightly
It is a sign that the student is performing this correctly when a single “Vibration” entirely exhausts his physical strength. It should cause him to grow hot all over, or to perspire violently, and it should so weaken him that he will find it difficult to remain standing.
It is a sign of success, though only by the student himself is it perceived, when he hears the name of the God vehemently roared forth, as if by the concourse of ten thousand thunders; and it should appear to him as if that Great Voice proceeded from the Universe, and not from himself.
The Golden Dawn's papers have the names pronounced inwardly, in the breath
The order's instruction has the name spoken inwardly and the whole body felt to throb with it, the vibration sent out to the ends of the quarter. The edition is in copyright and is cited, not quoted.
