I don't know what software you use, but for me, I get all the voices done first and add the audio track underneath the video track, just like with video editing software. With mine, when you click on a frame, it plays the sound from that frame. I also have the option to playback, so I know exactly what I'm doing when I animate dialogue. My suggestion: if you can't do this with your software, upgrade to a software that can. Trust me, it's worth doing!

I used to do it your way Headpods, however as you said it can be time consuming at times (especially when I somehow never thought of breaking up the dialogue recording sessions so that I didn't have to start again if I messed up half-way through ).

Now, I use a free software called Audacity (absolutely amazing) for recording dialogue (which I now do before I start animating) and then either after I have finished the animation I pair it up in an editing software (even the simplest should be able to do that) or (and this is only in certain circumstances) I will pair it up with my animation while I'm animating in Dragonframe, usually if I am needing to exaggerate/emphasise what is being said.

Unfortunately, having done a quick search as far as I'm aware Dragonframe is the only one that I can find, however, you may find something if you do some more searching or perhaps someone else knows of something.

Thanks for the info. I try and search.
