Prevent an audio source from playing a clip until the previous clip is finished.

Hey everyone. I'm creating a survival shooter game but I am having an issue when triggering sounds for an enemy getting hurt. I've scripted it that when the enemy takes damage, one of three random audio clips from an array will play. I've tried to script it so that a clip will not play if the previous one is still playing (to prevent it from continuously cutting off the previous clip and playing the next one every time they are hit), but it is not working. I'm relatively new to coding so I apologize if there is a simple mistake I am overlooking, but I have not found a solution in my research so far.

I've posted the relevant code below.

 public AudioClip [] hurtSounds;
 
 AudioSource enemyAudio;
 
 void Awake ()
 
     {
          enemyAudio = GetComponent <AudioSource> ();
     }
 
   public void TakeDamage (int amount, Vector3 hitPoint)
     {
         enemyAudio.clip = hurtSounds[Random.Range (0,2)];
   
 
         if (!enemyAudio.isPlaying) 
         {
             enemyAudio.Play ();
         }
     }

Thank you in advance!
