Question

我正在尝试统一测试语音识别程序。我正在使用UnityEngine.Windows.Speech.KeywordRecognizer。但是，每当我运行该程序时，都会出现以下错误：

MissingMethodException：尝试访问一个缺少方法。 UnityEngine.Windows.Speech.KeywordRecognizer..ctor （System.String []关键字，UnityEngine.Windows.Speech.ConfidenceLevel minimumConfidence）（在 /Users/builduser/buildslave/unity/build/Runtime/Export/Windows/Speech.cs:221） UnityEngine.Windows.Speech.KeywordRecognizer..ctor（System.String [] 关键字）（在 /Users/builduser/buildslave/unity/build/Runtime/Export/Windows/Speech.cs:201） VoiceRecognition.Start（）（位于Assets / VoiceRecognition.cs：23）

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Windows.Speech;
using UnityEngine.UI;

public class VoiceRecognition : MonoBehaviour
{
    public string[] keywords = { "right", "left", "up", "down" };
    public ConfidenceLevel confidence = ConfidenceLevel.Low;
    public float speed = 1;

    public Text results;
    public Image target;

    private KeywordRecognizer recognizer;
    protected string word = "right";

    private void Start()
    {
        if (keywords != null)
        {
            recognizer = new KeywordRecognizer(keywords, confidence); #Source of error
            recognizer.OnPhraseRecognized += Recognizer_OnPhraseRecognized;
            recognizer.Start();
        }
    }

    private void Recognizer_OnPhraseRecognized(PhraseRecognizedEventArgs args)
    {
        word = args.text;
        results.text = "You said: <b>" + word + "</b>";
    }

    #Code to move image
    private void Update()
    {
        var x = target.transform.position.x;
        var y = target.transform.position.y;

        switch (word)
        {
            case "up":
                y += speed;
                break;
            case "down":
                y -= speed;
                break;
            case "left":
                x -= speed;
                break;
            case "right":
                x += speed;
                break;
        }

        target.transform.position = new Vector3(x, y, 0);
    }

    private void OnApplicationQuit()
    {
        if (recognizer != null && recognizer.IsRunning)
        {
            recognizer.OnPhraseRecognized -= Recognizer_OnPhraseRecognized;
            recognizer.Stop();
        }
    }
}

当用户说“向右”，“向左”，“向上”或“向下”时，我希望能够移动图像，但是我一直收到MissingMethodException，并且无论如何我的图像都向一个方向移动我所说的话。

自从您提到MacOS以来，我很遗憾地告诉您，您使用的API方法仅适用于Windows 10。

摘自文档：Keyword recognizer is currently functional only on Windows 10.
