  Here an example. I use either a trigger or a bool (if it is looping) to change the animation states, in this case the face expression, during a dialogue. I set an Actionlist like this:

  When using Mecanim or Sprites Unity Complex, AC animates characters by controlling Animator parameter values. It's the same when using expressions.

  It's possible to insert tokens into your speech text of the form [expression:Name], in order to update a character's active expression. For example:

  [expression:Happy]It's the weekend! [expression:Sad]Oh, but it's raining.
  

  For these to have an effect, you'll need to define "Happy" and "Sad" expressions in your character's Inspector. When doing so, you'll find that expressions each have an ID number, e.g. Happy is 0, Sad is 1, etc.

  If you then go and define an Integer parameter in your Animator, and define that as the character's Expression ID integer, you'll find that this parameter always takes the ID value of the character's active expression.

  So in the example above, it'll be set to "0" when they say "It's the weekend!" and "1" when they say "Oh, but it's raining."

  How you make use of this parameter, however, is more open-ended. You can either use it to trigger transitions between different talking-animations, or you can use a simple script to convert it to a Float parameter and use it in a Blend tree, for example:

  void Update ()
  {
      int expressionID = GetComponent <Animator>().GetInteger ("ExpressionID");
      GetComponent <Animator>().SetFloat ("ExpressionFloat", (float) expressionID);
  }
