test for sound playing

Hi I want to string a series of sounds together, (phrases in to a sentence), is there a way of checking whether a sound has completed playing?

I've searched in the forum, and the only suggestions I could find is  using 'do after', but this complicated things as my phrases are all different lengths.

The ideal would be if I could set a boolean back to false when a channel is not playing anything.

Any ideas anyone?

cheers.

Use the sound events for that.

great thanks.
