Question by ThomasAqtl · Dec 14, 2020 at 07:11 PM · inputkeyword

KeywordRecognizer does not seem to work

Hi everyone,
This is my very first question on this site so I apologize if I'm at the wrong place.
I am working on gaze-based interactions in VR with Unity (v2018.3.14f1) and I want to use KeywordRecognizer class to suit my needs. I used the script from the doc KeywordRecognizer. However nothing happens once I play. Here is my script :

 using UnityEngine;
 using UnityEngine.Windows.Speech;
 using System.Text;
 using System;
 public class VoiceManager : MonoBehaviour
 {
     private string[] m_Keywords;
 
     private KeywordRecognizer m_Recognizer;
 
     void Start()
     {
         m_Keywords = new string[] { "take", "drop" };
         m_Recognizer = new KeywordRecognizer(m_Keywords, ConfidenceLevel.Low);
         m_Recognizer.OnPhraseRecognized += OnPhraseRecognized;
         m_Recognizer.Start();
     }
 
     private void OnPhraseRecognized(PhraseRecognizedEventArgs args)
     {
         print("OnPhraseRecognized called");
         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());
     }
 }

What bothers me is that the last time I tried it DID work. I changed nothing since. The line with print("OnPhraseRecognized called"); is only here to see if the function is called. But once in game, no matter what I say, nothing happens.

I am using VIVE Pro Eye for voice input.

Regards
