Do any of you sleeptalk while you’re having a lucid dream?
Just curious. 
Wired,
I think it’s unlikely that you will sleeptalk unless you know that it’s something you already do in your non-lucid dreams. Even when it feels like you are saying something loudly in your dream it’s not usually the case that you are uttering it in reality.
Are you worried that you might shout the wrong name? 
lol yeah I get worried about this too whenever I talk in my LD’s … my parents haven’t said anything yet so I assume that when we talk in LD’s we don’t sleep talk … even though it may feel like it! 
Sleeptalking usually occurs in Delta, or quiet sleep, so you probably won’t be dreaming while your sleep talking…so no worries about saying something embarrassing in a lucid dream and having someone else hear it
I have never sleeptalked while LD’ing. I don’t remember to have seen something like that on the forum. I agree with Josh Redstone, it seems to me that sleeptalking occurs during nREM sleep, but LD’s occurs generally during REM sleep, hence sleeptalking in LD’s would be very uncommon.
This seems highly unlikely to me, where did you get this information? As far as I know you are fully paralized in deep sleep (nREM phase 3 and especially 4). I have been lucid on occasion in this stage and there is no way you feel your physical body here (which I think is a requirement to speak).

Actually it’s the other way around, you generally become paralyzed during REM, and in nREM you can experience myoclonic jerks, toss and turn in your sleep, get muscle twitches, etc. Again, thats from EWLD.
What Xetrov said above surprised me too. 
my brother falls asleep easily, and sometimes, I can hear him talking, sometimes it’s bubbling, but sometimes he says understandable things (but without any sense). And I usually try to speak back to him by saying: “What did you say?”, and almost ever he answer me by saying the same thing. But if I insist too much he awakes. Once when he told me something, I told him that he’s sleeping and dreaming, and he told me: “Who?, me?, no, i’m not dreaming”.
He always forget what I say back to him, or what he says.
I once screamed “Increase Lucidity Now” in a dream, and I woke up affraid of actually having screamed it IRL!
Ok let me explain it more in depth. nREM is devided up into 4 parts and Josh, you seem to bundle them up as 1 whole: “in nREM you can experience myoclonic jerks, toss and turn in your sleep, get muscle twitches”… I see this done very often here on this site and it just doesnt make any sense at all. nREM stages 1 and 2 is what you are speaking about (perhaps also part of stage 3), but NOT stage 4 deep sleep, im 100% sure about that. All these things we are speaking about here on the forum that can happen during non-REM (dreams, muscle spasms, whatevers) ALL happen only in these stages 1 up till 3 (where you go as deep as theta combined with small bits of delta, brainwave-wise), and not in stage 4 where you are almost all the way into deep delta brainwaves. I dont know if you are aware what this means, but in deep delta the neo-cortex parts of your brain shut down and only basic systems stay active, so there is no way you can dream here, or move yourself, or speak.
So in the end it comes down to:
nREM stages 1 to 3 + REM : dreams
nREM stage 4 + REM : paralyzed
You see the fact that during nREM stages 1, 2 and 3 you are not paralyzed and yet you do have occasional dreams, partly explains the muscle spasms and twichtes you can have here because you might actually be acting out your dream.
Where did you get this info Xetrov? I’ve never read anything like this before now, so I’d be curious to read about it more.
For an oversight on sleep stages (also handy if you are already familiar, just because its a lot of info!)

To continue, i have read a plethora of scientific articles in the past few years on all related topics, it would be too much to mention them all here. If you have specific questions I can try to seek related information (for example, on deep sleep and brain functions etc). Also, a great deal of the info I gave, comes from first hand experience and from discussions with some other very advanced and experienced lucid dreamers (Jeff for one, but also Dm7).
I often wake myself up talking in my dreams out loud which at first was annoying if I am having a good, or coming out of one I should say… I have done this most of my life so in may not be something many people tend to do. It doesn’t seem to matter if its a ld dream or not.
I realize when i am doing this I am not fully in REM sleep, or I would be paralyzed. I am somewhere in between stages. It also said you go through these stages at least three times each nigh, many people wake up in-between. I just read a good article on the stages of sleep and the other poster is very correct about this, they think the paralyzing state is so people do not hurt themselves while dreaming, kick your partner or fall out of bed.
Yet I have found I can still use this to get into a lucid state by not stopping the dialog. I continue the dialog, and as I have began to do this over time - I no longer startle myself into a full waking state. I tend to drift back to sleep often into a lucid dream.
Alas I sleep alone at the moment so talking, its not an issue, but has been in the past!
Peace
