windows 语音识别！

  The Recognition namespace contains Windows Desktop Speech technology types for implementing speech recognition.

The Windows Desktop Speech Technology software offers a basic speech recognition infrastructure that digitizes acoustical signals, and recovers words and speech elements from audio input.

   Applications use System.Speech.Recognition namespace to access and extend this basic speech recognition technology, by defining algorithms for identifying and acting on specific phrases or word patterns, and by managing the run time behavior of this speech infrastructure.

 Applications manage and obtain use grammars -- sets of rules defining how specific combinations of words and phrases are to be understood --through the general purposeGrammar class, which hosts runtime, persisted, or dynamically constructed instances ofSrgsDocument.SrgsDocument instances contain W3C Speech Recognition Grammar Specification (SRGS) compliant grammar documents.

A simplified means of specifying grammar documents is provided through the GrammarBuilder and Choices classes. Full support for generating SRGS compliant grammars is provided by the members of theSystem.Speech.Recognition.SrgsGrammar name space.

   我在讲一下，GrammarBuilder类

  The Speech platform offers the GrammarBuilder class as a simple mechanism for constructingGrammar objects programmatically. Unlike the construction of Grammar instances from objects created using the System.Speech.Recognition.SrgsGrammar namespace, creating Grammar objects through a GrammarBuilder does not require a detailed understanding of the Speech Recognition Grammar Specification (SRGS).

To construct a basic Grammar object from a GrammarBuilder the following steps are required:

1. Create an appropriate GrammarBuilder instance. For more information on creatingGrammar objects see GrammarBuilder, Add and Addition.

2. Append to the GrammarBuilder objects which support grammar logic such as external reference to external rules, the Speech platform provided dictation grammars,[System.String],Choices,SemanticResultKey,SemanticResultValue, and other GrammarBuilder instances. For more information, seeAppend.

3. Construct a Grammar object from the GrammarBuilder using a Grammar.Grammar(GrammarBuilder) .

To support debugging, the current status of a GrammarBuilder can be written to a string usingDebugShowPhrases.

 System.Speech.Synthesis

The System.Speech.Synthesis namespace contains classes for initializing and configuring a speech synthesis engine, for creating prompts, for generating speech, for responding to events, and for modifying voice characteristics

这个System.Speech.Synthesis 命名含有初始化和配置一个对话，为了创造提示，为了发生，为了回应

System.Globalization Namespace

The System.Globalization namespace contains classes that define culture-related information, including language, country/region, calendars in use, format patterns for dates, currency, and numbers, and sort order for strings. These classes are useful for writing globalized (internationalized) applications. Classes such asStringInfo andTextInfo provide advanced globalization functionalities, including surrogate support and text element processing

EventHandler<TEventArgs> Delegate

The event model in the .NET Framework is based on having an event delegate that connects an event with its handler. To raise an event, two elements are needed:

• A delegate that refers to a method that provides the response to the event.

• A class that holds the event data.

这个事件在.net  framework 是基于有一个事件代理

The delegate is a type that defines a signature, that is, the return value type and parameter list types for a method. You can use the delegate type to declare a variable that can refer to any method with the same signature as the delegate.

The standard signature of an event handler delegate defines a method that does not return a value, whose first parameter is of typeObject and refers to the instance that raises the event, and whose second parameter is derived from typeEventArgs and holds the event data. If the event does not generate event data, the second parameter is simply an instance ofEventArgs. Otherwise, the second parameter is a custom type derived from EventArgs and supplies any fields or properties needed to hold the event data

那个代理是一个定义签名类型，那个返回类型和参数列表类型的方法。

SpeechRecognizer.SpeechRecognitionRejected Event

The shared recognizer raises this event if it determines that input does not match with sufficient confidence any of the loaded speech recognition grammars. TheResult property of theSpeechRecognitionRejectedEventArgs contains the rejected RecognitionResult object.

Confidence thresholds for the shared recognizer, managed by SpeechRecognizer, are associated with a user profile and stored in the Windows registry. Applications should not write changes to the registry for the properties of the shared recognizer.

When you create a delegate for a SpeechRecognitionRejected event, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate.
