关键字识别

  • Step 1: 定义字符串数组
  • Step 2: 订阅和处理OnPhraseRecognized事件。当给定短语被识别时,将调用此事件。.
  • Step 3: 开始关键字识别
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using UnityEngine.Windows.Speech;

public class KeyWordRecognizerBehaviour : MonoBehaviour {
	
	KeywordRecognizer keywordRecognizer;
	// keyword array
	public string[] Keywords_array;

	// Use this for initialization
	void Start () {
		// Change size of array for your requirement
		Keywords_array = new string[2];
		Keywords_array [0] = "hello";
		Keywords_array [1] = "how are you";

		// instantiate keyword recognizer, pass keyword array in the constructor
		keywordRecognizer = new KeywordRecognizer(Keywords_array);
		keywordRecognizer.OnPhraseRecognized += OnKeywordsRecognized;
		// start keyword recognizer
		keywordRecognizer.Start ();
	}

	void OnKeywordsRecognized(PhraseRecognizedEventArgs args)
	{
		Debug.Log ("Keyword: " + args.text + "; Confidence: " + args.confidence + "; Start Time: " + args.phraseStartTime + "; Duration: "  + args.phraseDuration);
		// write your logic
	}
}

如果在项目中使用多个关键字识别器,可以使用PhraseRecognitionSystem类用一行代码停止并重新启动所有关键字识别。

// shut down phrase recognition system. All keyword recognizer will be stopped
PhraseRecognitionSystem.Shutdown();
// restore all recognizer in the previous state
PhraseRecognitionSystem.Restart();
