Mine have never been very articulate at a young age. I say, don't worry about their speech ability. You can compare, but it will only drive you crazy. My first only used sign language until she was 22 months old. Then she started speaking in simple sentences. My second didn't make a sound or peep until a few months after his second birthday. (We'd hear him babbling a little to himself if he was alone, but he wouldn't make any noise in front of people.) When he started talking, it was complete sentences that were completely understandable. (We're talking complex sentences. Not just "Want milk." But "Could you get me a cup of milk.") My third is 18 months old now and he does say a few words here and there.
Each child is different. 14 months is too early to be worried about speech. If they are 2 and a half and can't talk, then you can find solutions, but for now, let him be.
