How to connect audio clip's with dialog?

Hi,

so, i’m working on a game, and i have a dialog between two people. I already make, that when the player click on button next, the next dialoge is shown. i have 9 dialogs, so the player must press 9 times on button next, to end up dialoge.

The problem i have now, that i want when text is shown the audio clip(i recorded voices and export as mp3 in audacity) is on volume too. i have 9 audio clips and i can’t pair it with texts.

any solutions?

Thanks

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?
