Is this a case of the text within the speech Action being truncated, or the display of it within Unity UI?
If you're using Unity's provided Text component, you can set its Vertical Overflow property to Overflow to prevent truncation - but I recommend increasing the size of the RectTransform (either manually or dynamically) so that AC can refer to it more accurately when it comes to repositioning.
