"I am wanting glasses."
Translation:Tha mi ag iarraidh speuclairean.
Slender dh (that is, when it has i or e on either of its sides, eg. idh, idhe, dhe, dhi…), has [ʝ ~ j] sound (similar to English y in yes). The broad dh (when it has a, o, u on its sides) is [ɣ] (the g-like sound but a fricative, not a stop).
And the dh sounds might disappear in some instances (eg. the slender one after /i/, so iarraidh is just /iəRi/ not /iəRij/; or the broad one in a middle of a word, but affecting the vowel before it, eg. radharc /rɤərg/).
