How to Remove Delay in Button Click to Animation

I am a noob to Unity, i am making a simple game that need fast response. so in GUI, there will be some button. if i press button X then do Animation X, then if i press button Y then do Animation Y. Currently, i just create one button to test.

But There's a problem. Whenever i click button X, there's a delay around 1-2 seconds until animation play.

Animator Scheme:

Button onClick Target:

TalkingButtonScript.cs :

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.UI;
 
 public class TalkingButtonScript : MonoBehaviour {
 
     public Button Text;
     public AudioClip sound;
     public Animator ani;
     public Canvas yourcanvas;
     Animator myAnimator;
     public PlayerAnimatorControllerScript cas;
 
     void Start () 
     {
         Text = Text.GetComponent<Button> ();
         ani.enabled = true;
         yourcanvas.enabled = true;
     }
         
     public void Press() 
     {
         PlayerAnimatorControllerScript.instance.talking_btn_clicked = true;
     }
 }
 

Maybe there's something wrong in my code, PlayerAnimatorControllerScript.cs :

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class PlayerAnimatorControllerScript : MonoBehaviour {
 
     public static PlayerAnimatorControllerScript instance;
     public float speed = 10.0f;
     public float jumpSpeed = 8.0f;
     public float gravity = 20.0f;
     private float total =0.0f;
     private Vector3 moveDirection = Vector3.zero;
     CharacterController controller;
     public Animator myAnimator;
     float currSpeed, Param1;
     bool Param2, Param3;
     public bool talking_btn_clicked = false;
 
     // Use this for initialization
     void Start () {
         instance = this;
         controller = GetComponent<CharacterController> ();
         myAnimator = GetComponent<Animator> ();
         //myAnimator.SetBool ("TalkingStatus", true);
     }
 
     public void talkingActive()
     {
         Debug.Log ("set talking button = active");
         talking_btn_clicked = true;
     }
         
     // Update is called once per frame
     void Update ()
     {
         Param1 = 0;
         Param2 = false;
         Param3 = false;
         if (controller.isGrounded) {
 
             if (talking_btn_clicked == true) {
                 myAnimator.SetBool ("TalkingStatus", true);
             }
                 
             currSpeed = speed;
             if (Input.GetKey (KeyCode.LeftShift)) {
                 Debug.Log ("ShiftLeft Pressed");
                 Param2 = true;
                 currSpeed = speed / 2;
             }
 
             if (Input.GetKey (KeyCode.LeftControl)) {
                 Param3 = true;
             }
 
 
             Param1 = Mathf.Abs (Input.GetAxis ("Vertical"));
             transform.Rotate (0, Input.GetAxis ("Horizontal"), 0);
             myAnimator.SetFloat ("Speed", Param1);
             myAnimator.SetBool ("Shift", Param2);
             myAnimator.SetBool ("Attack", Param3);
             moveDirection = new Vector3 (0, 0, Input.GetAxis ("Vertical"));
             moveDirection = transform.TransformDirection (moveDirection);
             moveDirection *= currSpeed;
 
             if (Input.GetButton ("Jump")) {
                 moveDirection.y = jumpSpeed;
                 Param1 = 0.2f;
             }
             
                     
         }//==controller.isGrounded        
         if (!myAnimator.IsInTransition(0)) {
             //Debug.Log("Animation is in Transition");
             total = gravity * Time.deltaTime;
             moveDirection.y -= gravity * Time.deltaTime;
             controller.Move (moveDirection * Time.deltaTime);
             //Debug.Log("total = "+total);
         }
     }//==update
 }//==class
 

btw, Thanks in advance...and sorry for my english...
