Speed the animation speed using Spine

Hi dear community,
I’m using an animation make it with Spine.
My character have to increase the animation speed over the time of game and if the player miss some mechanic it will be reset to the normal speed. I’m looking in the sp.skeleton api, but i haven’t found any information about the speed or the animation.

Any help?

I found a property that makes the tirck.

TimeScale is the solution!
