KeywordRecognizer

Description

KeywordRecognizer listens to speech input and attempts to match uttered phrases to a list of registered keywords.

There can be many keyword recognizers active at any given time, but no two keyword recognizers may be listening for the same keyword.

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());
    }
}

Keyword recognizer is currently functional only on Windows 10.
