Does the keyword recognizer understand phrases?

Question

I am using the keyword recognizer in Unity to display output on specific keyword and I am able to detect words like red or green.

 keywords.Add("Red", () =>{Red();});
         keywords.Add("white", () => { white(); });

However, the recognizer does not work when I use a phrase in the dictionery.

 keywords.Add("Red Ball", () =>{Red();});

It doesn't detect the phrase red ball. If I make them as two different functions then I have to speak both words far apart in time. Is there a way to detect phrases in the UNity phrase recognition?

Have you tried setting the ConfidenceLevel to Low? We have fairly good results in our tries with longer words as well as two word phrases.

 using UnityEngine.Windows.Speech;
 
 KeywordRecognizer keywordRecognizer = null;
 
 void Start() {
     keywordRecognizer = new KeywordRecognizer(words, ConfidenceLevel.Low);
     keywordRecognizer.OnPhraseRecognized += OnPhraseRecognized;
     keywordRecognizer.Start();
 }
 
 void OnPhraseRecognized(PhraseRecognizedEventArgs args) {
     Debug.Log("We recognized \"" + speech + "\" with confidence " + args.confidence);
 }

Also, there's PhraseRecognizer instead of KeywordRecognizer, though I haven't yet tried that.

I have recently come across this problem as well with the keyword recognizer. I'm going to attempt PhraseRecognizer this week. I'll keep you guys posted if I can get it working.
