Summary

Christian Brothers Aids to the Pronunciation of Irish (1905)

For the production of the broad sounds of D and T the tongue is pressed against the upper teeth (the tongue does not touch the gums) . The only difference between d and t is that d is voiced (§ 3) , t voiceless.
Throughout the most of Ireland the English sounds of “th” are never heard. The vast majority of Irishmen employ the broad sounds of t and d. In English “th” is not a “stop,” it is a spirant, the tongue being placed between the teeth in such a way that the breath is not completely stopped.
(a) Broad s in Irish has not quite so hissing a sound as the English “s.”

Initial slender r is usually pronounced broad, except in aspirable positions, when it gets its slender sound.
(c) The slender sound of r is produced by spread in the tongue and forming a small hollow in the front portion of it. The point of the tongue is brought close to the gum just above the upper teeth (i.e., below the “hard rim”) . The stream of voiced breath is directed into the hollow in the front of the tongue, and can be felt striking the lower lip.
