Question

我试图在使用Android并试图实现语音识别和手机的手机中连接麦克风。我想使用Microsot.Speech库，问题是我怎样才能访问麦克风。请查看微软网站上的示例代码：

using System;
using Microsoft.Speech.Recognition;

namespace SpeechRecognitionApp
{
  class Program
  {
    static void Main(string[] args)
    {

      // Create a SpeechRecognitionEngine object for the default recognizer in the en-US locale.
      using (
      SpeechRecognitionEngine recognizer =
        new SpeechRecognitionEngine(
          new System.Globalization.CultureInfo("en-US")))
      {

        // Create a grammar for finding services in different cities.
        Choices services = new Choices(new string[] { "restaurants", "hotels", "gas stations" });
        Choices cities = new Choices(new string[] { "Seattle", "Boston", "Dallas" });

        GrammarBuilder findServices = new GrammarBuilder("Find");
        findServices.Append(services);
        findServices.Append("near");
        findServices.Append(cities);

        // Create a Grammar object from the GrammarBuilder and load it to the recognizer.
        Grammar servicesGrammar = new Grammar(findServices);
        recognizer.LoadGrammarAsync(servicesGrammar);

        // Add a handler for the speech recognized event.
        recognizer.SpeechRecognized +=
          new EventHandler<SpeechRecognizedEventArgs>(recognizer_SpeechRecognized);

        // Configure the input to the speech recognizer.
        recognizer.SetInputToDefaultAudioDevice();

        // Start asynchronous, continuous speech recognition.
        recognizer.RecognizeAsync(RecognizeMode.Multiple);

        // Keep the console window open.
        while (true)
        {
          Console.ReadLine();
        }
      }
    }

    // Handle the SpeechRecognized event.
    static void recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {
      Console.WriteLine("Recognized text: " + e.Result.Text);
    }}}

我认为这里的兴趣点是：

recognizer.SetInputToDefaultAudioDevice();

如何将输入更改为设备麦克风？非常感谢。

将Microsoft.Speech与xamarin联系起来
