How to connect audio clip's with dialog?

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.EventSystems;
 using UnityEngine.SceneManagement;
 using TMPro;
 public class Dialog : MonoBehaviour
 {
     // Start is called before the first frame update
 
     public TextMeshProUGUI textDisplay;
     public string[] sentences;
     private int index;
     public float typingSpeed;
 
     public GameObject continueButton;
     void Start()
     {
         StartCoroutine(Type());
     }
     void Update()
     {
         if(textDisplay.text == sentences[index])
         {
             continueButton.SetActive(true);
         }
     }
     IEnumerator Type()
     {
         foreach(char letter in sentences[index].ToCharArray())
         {
             textDisplay.text += letter;
             yield return new WaitForSeconds(typingSpeed);
         }
     }
     public void NextSentence()
     {
         continueButton.SetActive(false);
 
         if(index < sentences.Length - 1)
         {
             index++;
             textDisplay.text = "";
             StartCoroutine(Type());
         
         } else {
             SceneManager.LoadScene("Animation"); ;
         }
         
     }
     
 }
 

So that's my code, what i must add to the code, so when the text is shown on screen, audio clip is played at same time? and every time i click on button next, the next sentence and audio clip is played?
