Multiple speech requests

Hey Nick!

It's working pretty good!
One issue is if speech is triggered and then another is triggered; then it tends to cause issues. Such as stuttering/repeating and causing any previously playing music to not resume.
Would be real nice if you had the option to queue speech i.e. so they are just played one after the other; or a 'forced' speech which simply has priority over any other speech. Not sure what you do if a priority speech intercepts another priority speech.
I suppose if the 'length' value was available it would be possible to have a trigger use this as a timer before allowing any more speech i.e. until current speech has ended.

But if I don't abuse it it seems good.
