我是C＃，HoloLens和Unity的新手。我想将Holograms 101的语音命令功能添加到Holograms 230。
完成Holograms 230后，我从Holograms 101获取了SpeechManager脚本，添加了一些Debug.Log命令，并将其拖到Unity的“Hierarchy”面板中的一个对象上。当我单击Unity中的“播放”按钮时，我的脚本会运行（事实证明我的Debug.Log出现在状态栏中）。但是当我构建并将其部署到HoloLens时（通过Visual Studio中的“Debug - ＆gt; Start Debugging”），我的新脚本中的Debug.Log不会显示在Visual Studio的“输出”面板中，甚至通过其他脚本的Debug.Log来做。
这是我的SpeechManager.cs：
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using UnityEngine;
using UnityEngine.Windows.Speech;
public class SpeechManager : MonoBehaviour {
KeywordRecognizer keywordRecognizer = null;
Dictionary<string, System.Action> keywords = new Dictionary<string, System.Action>();
// Use this for initialization
void Start () {
Debug.Log("!!Starting speech manager");
keywords.Add("Place item", () =>
{
Debug.Log("!!Place item");
});
// Tell the KeywordRecognizer about our keywords.
keywordRecognizer = new KeywordRecognizer(keywords.Keys.ToArray());
// Register a callback for the KeywordRecognizer and start recognizing!
keywordRecognizer.OnPhraseRecognized += KeywordRecognizer_OnPhraseRecognized;
keywordRecognizer.Start();
}
private void KeywordRecognizer_OnPhraseRecognized(PhraseRecognizedEventArgs args)
{
System.Action keywordAction;
if (keywords.TryGetValue(args.text, out keywordAction))
{
keywordAction.Invoke();
}
}
}
这是另一个附加到Unity中相同对象的脚本，它正常运行并触发Debug.Log s：

using UnityEngine;
using UnityEngine.Windows.Speech;
