谷歌語音識別不起作用

Question

所以我最近決定再次重做我的賈維斯AI的基礎設施。現在我正在使用代碼組合（谷歌和微軟）。代碼中的Google部分不會因某種原因而觸發，並在向麥克風說話時顯示任何文字或文字。

public const int DEFAULT_BIT_RATE = 8000; 
public const string DEFAULT_LANGUAGE = "en-US"; 
static string client = "Jarvis"; 
public class SpeechInputResult 
{ 
     static public string ID; 
     public int status; 

     public class Hypothesis 
     { 
      public string utterance; 
      public double confidence = -1.0d;//-1 = No Value 
      public override string ToString() 
      { 
       return "'" +utterance + "'" + ((confidence == -1) ? "" : "@" + confidence); 
      } 
      public List<Hypothesis> hypotheses = new List<Hypothesis>(); 

      public Hypothesis getBestHypothesis() 
      { 
       if (hypotheses.Count() <=0) 
        return null; 
       Hypothesis H = hypotheses[0]; 
       foreach (Hypothesis h in hypotheses) 
       { 
        if (h.confidence>=H.confidence) 
        { 
         H = h; 
        } 
        return H; 
       } 
       return null; 
      } 
      public string json_men = ""; 
      public void FromJSON(String JSON) 
      { 
       json_men = JSON; 
       JSON = JSON.Replace("\n","").Trim(); 
       Match M; 

       //status 
       M = new Regex("\\\"status\\\"\\:([0-9]*),", RegexOptions.IgnoreCase).Match(JSON); 

       //ID 
       M = new Regex ("\\\"id\\\"\\:\\\"([^\\\"]*)\\\",", RegexOptions.IgnoreCase).Match(JSON); 
       ID = M.Groups[1].Value; 

       //Hypotheses 
       int l1 = JSON.IndexOf("hypotheses"); 
        l1 = JSON.IndexOf("[",l1); 
       int r1 = JSON.LastIndexOf("]"); 
       string JSON2 = JSON.Substring(l1, r1-l1+1); 

       MatchCollection m2 = new Regex("{([^\\}]*)}", RegexOptions.IgnoreCase).Matches(JSON2); 
       foreach (Match g in m2) 
       { 
        string s = g.Value; 
        SpeechInputResult.Hypothesis h = new SpeechInputResult.Hypothesis(); 

        M = new Regex("\\\"utterance\\\"\\:\\\"([^\\\"]*)\\\"", RegexOptions.IgnoreCase).Match(s); 
        h.utterance = M.Groups[1].Value; 

        M = new Regex("\\\"confidence\\\"\\:([0-9\\.]*)", RegexOptions.IgnoreCase).Match(s); 
        string confidence = M.Groups[1].Value; 
        confidence = confidence.Replace(".", ","); 
        if (confidence != "") 
        { 
         h.confidence = float.Parse(confidence); 
        } 
        hypotheses.Add(h); 
       } 
      } 
     } 
     public static SpeechInputResult ProcessFlacFile(string FlacFileName, int BIT_RATE = DEFAULT_BIT_RATE, string language = DEFAULT_LANGUAGE, uint maxresults = 1) 
     { 
      HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("https://www.google.com/speech-api/v1/recognize?xjerr=1" + "&client=" + client + "&lang=" + language + "&maxresults=" + maxresults + "&pfilter=0"); 
      FileStream fStream = new FileStream(FlacFileName, FileMode.Open, FileAccess.Read); 
      request.Proxy = null; 
      request.Timeout = 60000; 
      request.KeepAlive = true; 
      request.Method = "POST"; 
      request.ContentType = "audio/x-flac; rate=8000"; 
      //bitrate must = .flac file 
      request.UserAgent = client; 
      FileInfo fInfo = new FileInfo(FlacFileName); 
      long numbytes = fInfo.Length; 
      byte[] data = null; 
      using (FileStream fstream = new FileStream(FlacFileName, FileMode.Open, FileAccess.Read)) 
       data = new byte[fstream.Length]; 
      fStream.Read(data, 0, Convert.ToInt32(fStream.Length)); 
      fStream.Close(); 
      using (Stream wrStream = request.GetRequestStream()) 
      { 
       wrStream.Write(data, 0, data.Length); 
      } 
      try 
      { 
       HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
       dynamic resp = response.GetResponseStream(); 
       if (resp != null) 
       { 
        StreamReader sr = new StreamReader(resp); 
        MessageBox.Show(sr.ReadToEnd()); 
        //resp.Close(); 
        //resp.Dispose(); 
       } 
      } 
      catch (System.Exception ee) 
      { 
       MessageBox.Show("hi"+ee); 
      } 
      return null; 
     } 
    } 
} 

這裏的代碼全部來自this website。

得到它沒有錯誤後，它仍然不會返回或做任何事情，請幫助！

用正則表達式解析JSON通常會導致問題。考慮使用類似JSON.NET的庫來將字符串解析爲對象。
