Play sound only once.

Question

Hi! i have a enemy and i want to play his sound, i play his sound when the player is near him, but if the player not move, all time it called, like a Update(), how could I call the sound correctly? Thanks :)

 if (target != initialPosition && distance < visionRadius)
 {
     sound.Play();
     anim.SetBool("Emerge", true);
     anim.SetBool("Hide", false);
     Debug.DrawLine(transform.position, target, Color.blue);
 }
 else
 {
     anim.SetBool("Hide", true);
     anim.SetBool("Emerge", false);
 }

And here is my animator and its transitions

 // class member
 private bool inSight;
 
 // ...
 if (target != initialPosition && distance < visionRadius)
 {
     if(!inSight)
     {
         sound.Play();
         anim.SetBool("Emerge", true);
         anim.SetBool("Hide", false);
         Debug.DrawLine(transform.position, target, Color.blue);
         inSight = true;
     }
 }
 else if(inSight)
 {
     anim.SetBool("Hide", true);
     anim.SetBool("Emerge", false);
     inSight = false;
 }
