Speech在Visual Basic中的文本

Question

我有用Visual Basic編寫的用於語音的文本代碼，但它只識別所說的第一個單詞或句子，然後停止識別。我希望它繼續傾聽。我怎樣才能做到這一點？問題是什麼？ 這裏是我的代碼現在：

Imports System.Speech 

Public Class Form1 

    Public synth As New Speech.Synthesis.SpeechSynthesizer 
    Public WithEvents recognizer As New Speech.Recognition.SpeechRecognitionEngine 
    Dim gram As New System.Speech.Recognition.DictationGrammar() 

    Public Sub GotSpeech(ByVal sender As Object, ByVal phrase As System.Speech.Recognition.SpeechRecognizedEventArgs) Handles recognizer.SpeechRecognized 
     words.Text += phrase.Result.Text & vbNewLine 
    End Sub 

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 
     recognizer.LoadGrammar(gram) 
     recognizer.SetInputToDefaultAudioDevice() 
     recognizer.RecognizeAsync() 
    End Sub 
End Class 

Answer 1

RecognizeAsync()做一個單一的認可。 RecognizeAsync(RecognizeMode.Multiple)將做多重認可。
