I modified the attached sample mission two posts above to include the lip file. The example now has both units doing this say command so their lips move for a few minutes:
this say "NoSoundLongLip";
For this to work, you will need the .ogg and .lip files in the Sound directory, and this entry in your description file:
class CfgSounds
{
sounds[] = {NoSoundLongLip};
class NoSoundLongLip
{
name = "NoSoundLongLip";
sound[] = {"NoSoundLongLip.ogg", db-20, 1.0};
titles[] = {0,""};
};
};
Note that in this case the .ogg file is a short file with no sound in it. Just a placeholder so the say command will work. The lip file was taken from a lip file of a guy singing a two minute (or so) song, so the lips move a long time. Not sure exactly how long though.
