Not to worry, my 2nd son didn't start speaking clearly until he was right around 3 years old. He was diagnosed with speech delay. However, all children are different. He does not stop talking now. My youngest son he will be 3 in May still doesn't have a very large vocabulary and I have discussed this with my pediatrician and this is the conclusion that we have come up with. We put my 2nd son in speech therapy and that helped a little. Then I decided that being around other kids his age (he was at home with me all the time, I am a stay at home mom) might be more productive. So I discussed with his pediatrician removing him from speech therapy and placing him in daycare with other kids his age and see if that would spark more of an interest in getting him talking. Sure enough that did it. Well I know that he would talk in his own time. I know that in my heart of hearts that my youngest son will talk when he is ready as well. He is saying quite a few words, just not carrying on conversations. If you are truly concerned about this I would discuss it with your pediatrician. As I said all kids learn and progress at their own rate. For example my oldest son was talking and carrying on conversations at 9 months old, which is highly unusual.
Good luck.
