如何在帶有 SpeechRecognizer EventArgs 變量的 TextBox 中放置換行符

Question

我正在創建一個語音識別器，我必須放置 SpeechRecognizer EventArgs 變量，但我希望我所說的內容累積在文本框中，當我停止並重新開始時，它不會被替換

我的代碼：

private void button2_Click_1(object sender, EventArgs e)
    {

        engine_load();

    }
    private void engine_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {
        textBox1.Multiline = true;
        textBox1.Text = e.Result.Text + Environment.NewLine;
    }

    private void engine_load()
    {


            engine = new SpeechRecognitionEngine();
            engine.SetInputToDefaultAudioDevice();
            Grammar g = new DictationGrammar();
            engine.LoadGrammar(g);
            engine.RecognizeAsync(RecognizeMode.Multiple);
            engine.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(engine_SpeechRecognized);
            Console.ReadLine();

    }

也許您可以聲明一個全局變量text來保存之前輸入的字符串。

請參考以下代碼。

string text;

private void engine_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
    textBox1.Multiline = true;
    text += e.Result.Text + Environment.NewLine;
    textBox1.Text = text;
}
