本文介绍了一个Unity中的语音识别系统实现，使用KeywordRecognizer类进行关键词识别，详细展示了如何创建识别器、设置关键词、启动识别及处理识别结果。文章还强调了在销毁时释放资源的重要性。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Windows.Speech;//引入命名空间  利用
public class speechKey : MonoBehaviour {
    /// <summary>
    /// 短语识别器
    /// </summary>
    private PhraseRecognizer m_PhraseRecognizer;
    /// <summary>
    /// 关键字
    /// </summary>
    public string[] keywords;
    /// <summary>
    /// 可信度
    /// </summary>
    public ConfidenceLevel m_confidenceLevel = ConfidenceLevel.Medium;

// Use this for initialization
void Start ()
{
    //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();
}
/// <summary>
/// 当识别到关键字时，会调用这个方法
/// </summary>
/// <param name="args"></param>
private void M_PhraseRecognizer_OnPhraseRecognized(PhraseRecognizedEventArgs args)
{        
    print(args.text);
}
private void OnDestroy()
{
    //用完应该释放，否则会带来额外的开销
    m_PhraseRecognizer.Dispose();
}
// Update is called once per frame
void Update ()
{
	
}
}
