描述
KeywordRecognizer 监听语音输入，并尝试将说出的短语与已注册的关键词列表匹配。
在任何给定时间，可能存在许多活动关键词识别器，但两个关键词识别器不能监听相同的关键词。

public class KeywordScript : MonoBehaviour

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());
}
}
关键词识别器目前仅在 Windows 10 上运行。
