Unity native speech recognition/no plug-ins/can be offline/no need for online speech recognition

• Just upload the code and make sure your device is connected to the microphone. Then hang the following code directly on the empty object in the scene and run it.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Windows.Speech;
//using UnityTools;
/// 语音识别
public class SpeechRecognition : MonoBehaviour
{
    
    
    // 短语识别器
    private PhraseRecognizer m_PhraseRecognizer;
    // 关键字
    public string[] keywords = {
    
     };
    // 可信度
    public ConfidenceLevel m_confidenceLevel = ConfidenceLevel.Medium;
    void Start()
    {
    
    
        if (m_PhraseRecognizer == null)
        {
    
    
            //创建一个识别器
            m_PhraseRecognizer = new KeywordRecognizer(keywords, m_confidenceLevel);
            //通过注册监听的方法
            m_PhraseRecognizer.OnPhraseRecognized += M_PhraseRecognizer_OnPhraseRecognized;
            //开启识别器
            m_PhraseRecognizer.Start();
        }
    }
    /// 当识别到关键字时，会调用这个方法
    private void M_PhraseRecognizer_OnPhraseRecognized(PhraseRecognizedEventArgs args)
    {
    
    
        _SpeechRecognition(args.text);
        print(args.text);
    }
    private void OnDestroy()
    {
    
    
        //判断场景中是否存在语音识别器，如果有，释放
        if (m_PhraseRecognizer != null)
            m_PhraseRecognizer.Dispose();
    }
    /// 识别到语音的操作
    void _SpeechRecognition(string msg)
    {
    
    
        switch (msg)
        {
    
    
            case "你好你好":
                Debug.Log("我在，你说");
                break;
            case "XXXXX":

        }
    }
