Again, a listening excercise. I know you're all chomping at the bits to learn how to actually say anything, but please bear with me. It will help you get your pronunciation and perception off to a good start.
1. Read the page on Articulatory Phonetics. Please don't try to understand and memorize everything I wrote there yet, just try to get a bit of an overview. Pay special attention to the sections on stops and laryngals only.
2. Go again to Radio nan Gaidheal and pick any show you might feel like listening to. Now, this time I want you to listen to the following: in Gaelic, words aren't separate entities like in English, but they all flow together. One of the consequences of this is that in the middle of a sentence, you don't add a glottal stop ([ʔ]) to the beginning of words that start with a vowel. You only do that when you have paused for breath, or at the beginning of a sentence. For comparison, another language that has the same behaviour in regard to this is French.
