注解

在语音识别器开始语音识别之前，必须至少加载一个识别语法并为识别器配置输入。

若要加载语法，请调用 LoadGrammar 或 LoadGrammarAsync 方法。

若要配置音频输入，请使用以下方法之一：

• SetInputToAudioStream

• SetInputToDefaultAudioDevice

• SetInputToNull

• SetInputToWaveFile

• SetInputToWaveStream

以下示例演示演示基本语音识别的控制台应用程序的一部分，并初始化 en-US 区域设置的语音识别器。

using System;
using System.Speech.Recognition;

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

      // Create an in-process speech recognizer for the en-US locale.
      using (
      SpeechRecognitionEngine recognizer =
        new SpeechRecognitionEngine(
          new System.Globalization.CultureInfo("en-US")))
      {

        // Create and load a dictation grammar.
        recognizer.LoadGrammar(new DictationGrammar());

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

        // Configure 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);
    }
  }
}

注解

Microsoft Windows 和 System.Speech API 接受所有有效的语言国家/地区代码。 若要使用参数中指定的 CultureInfo 语言执行语音识别，必须安装支持该语言国家/地区的代码的语音识别引擎。 Microsoft Windows 7 附带的语音识别引擎适用于以下语言国家/地区代码。

• en-GB。 英语(英国)

• en-US。 英语（美国）

• de-DE。 德语（德国）

• es-ES。 西班牙语(西班牙)

• fr-FR。 法语(法国)

• ja-JP。 日语（日本）

• zh-CN。 中文（中国）

• zh-TW。 中文（台湾）

还允许使用双字母语言代码，如“en”、“fr”或“es”。

在语音识别器开始识别之前，必须至少加载一个语音识别语法并为识别器配置输入。

若要加载语法，请调用 LoadGrammar 或 LoadGrammarAsync 方法。

若要配置音频输入，请使用以下方法之一：

• SetInputToAudioStream

• SetInputToDefaultAudioDevice

• SetInputToNull

• SetInputToWaveFile

• SetInputToWaveStream
