Sindarin was the Elvish language most commonly spoken in Middle Earth in the Third age. Sindarin was designed to have a Welsh like phonology and It has most of the same sounds. So if you can speak welsh you'll find it easier to learn Sindarin. No one can ever learn Sindarin fluently because it's not a complete language but you can learn some words and phrases from here. All of the words phrases I used I got from several diffrent websites. So I don't know that all of them are 100% accurate but I try to check and make sure that they are.
