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.

#pragma strict
public class KeywordScript extends MonoBehaviour {

@SerializeField private var m_Keywords: String[];

private var m_Recognizer: KeywordRecognizer;

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

private function OnPhraseRecognized(args: PhraseRecognizedEventArgs) { var builder: var = 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()); } }
