So I don't have the text to speach and thus far the only letter I have absolutely no idea how to pronounce is "I" and "i". So A)how do I get text to speach to work and B) how are those two letters pronounced?
Audio is not yet working for Android. And even on the Web and for iOS, only a few sentences have been recorded yet. More will be added over time.
When you are in Duolingo, look carefully at the bottom of all tall straight letters. There is a curl at the bottom of the l (lowercase L) that is not present at the bottom of the I (uppercase i). In Klingon, L is always lowercase (l) and i is always uppercase (I).
The Klingon l is pronounced exactly as in English. In English we have a few different ways to say the letter i, but the Klingon I is always pronounced like in "it" and not like in "ring" or "lite".
