KeywordRecognizer

class in UnityEngine.Windows.Speech

继承自：Windows.Speech.PhraseRecognizer

描述

KeywordRecognizer 监听语音输入，并尝试将说出的短语与注册关键字列表匹配。

在任何给定的时间点可能有许多关键字识别器同时处于活动状态，但是没有哪两个关键字识别器监听同一个关键字。

using UnityEngine.Windows.Speech;

public class KeywordScript : MonoBehaviour
{
    [SerializeField]
    private string[] m_Keywords;

    private KeywordRecognizer m_Recognizer;

    void Start()
    {
        m_Recognizer = new KeywordRecognizer(m_Keywords);
        m_Recognizer.OnPhraseRecognized += OnPhraseRecognized;
        m_Recognizer.Start();
    }

    private void OnPhraseRecognized(PhraseRecognizedEventArgs args)
    {
        StringBuilder builder = new StringBuilder();
        builder.AppendFormat("{0} ({1}){2}", args.text, args.confidence, Environment.NewLine);
        builder.AppendFormat("\tTimestamp: {0}{1}", args.phraseStartTime, Environment.NewLine);
        builder.AppendFormat("\tDuration: {0} seconds{1}", args.phraseDuration.TotalSeconds, Environment.NewLine);
        Debug.Log(builder.ToString());
    }
}

关键字识别器目前仅在 Windows 10 上可用。
