Hey
This is my first post, so dont rip me apart too much :P
One thing that has always baffled me about star trek is the comm badges. When one of the crew wants to communicate with another, they press the badge, say their name and miraculously start talking to him/her. What confuses me is how the reciever hears his name being said. The sender does not distinguish who he wants to talk to until he says the persons name, by which time the reciever is hearing the conversation. Its like picking up a phone, saying a name without ringing, and immediately starting to talk to someone, the exact person you wanted, without anybody else hearing!
I am sure someone on here will have an intelligent response XD

Actually, there's no indication whatsoever that the connection occurs prior to the entire phrase being stated, nor any indication that the person at the receiving end hears what's originally stated by the "caller."
Let's look at this from the standpoint of a "voice dial" feature on a contemporary cell phone.
I can preprogram a number of dial-ups which I can dial just by saying a name. For instance, when wearing my little bluetooth headset, I can just tap the side button, wait for a beep, and say "Christi's apartment" and it connects through.
Further, when someone calls me, I get a "caller ID" signal identifying the person calling.
This isn't a "real time analog" call. At my end, what I'm saying is converted into a digitally encoded signal, which is then passed through a signal-recognition program to identify what I've said, and correlate that to a digital command (in this case, to dial a specific number sequence). Then, the signal is passed through to the end user who gets to see who's calling.
Now... imagine just a tiny tweak to this. Imagine that your voice signal is interpreted by a "central switchboard" (in most cases in TNG, this would be the ship's computer. Prior to beaming down someplace, you'd get "preprogrammed" with key command sequences, including each of your party members... plus a limited ability to put out an "in the clear page" that everyone could intercept).
So, you say "Picard to Enterprise." Your combadge knows that you're off the ship, and knows what number to "dial" to get back to the ship. It executes a preprogrammed "dialing sequence" and sends an encoded copy of what you'd said as a form of "caller ID."
On the ship, this "call" is received. And whoever is manning the communication station (or equivalent functionality) hears your PRE-RECORDED "caller ID" voice message... sent along with your call... saying "Picard to Enterprise." This might be a measurable time later... perhaps as much as a second or two, though more likely less than a second in most circumstances.
From the standpoint of the caller and the receiver, it's essentially "magic" but it's not... it's digital communication replicating vocal patterns. You're not actually hearing the voice of the person you're talking to, you're hearing a digital encoding and reconstruction of that voice, which has been manipulated in all variety of ways along the way.
