The example uses the collection returned by the InstalledRecognizers method to find a speech recognizer that supports the English language. The following example shows part of a console application that demonstrates basic speech recognition.

The following illustration shows a RecognizerGuide structure with two lines for input. If a user writes on the lines, instead of some arbitrary space, recognition accuracy improves. For example, you can draw horizontal lines on a user's screen, almost like a ruled piece of paper, that show where handwriting should occur (this type of guide would consist only of rows, and no columns). The recognizer guide can consist of rows and columns, and gives the recognizer a better context in which to perform recognition. The RecognitionResult object can be persisted with the original Strokes collection from which it was generated. The results contain a best result string in the TopString property, as well as a collection of alternative results in a RecognitionAlternates collection. The results of the recognition are returned in a RecognitionResult object. RecognitionResult and RecognitionAlternate Objects MessageBox.Show("No recognizers installed.") RecoContext = defReco.CreateRecognizerContext() Recognizer defReco = recos.GetDefaultRecognizer() Recognizers recos = new Recognizers() //Check for recognizer. ::MessageBox(NULL, TEXT("No recognizers installed.\nExiting."), Hr = CoCreateInstance(CLSID_InkRecognizerContext, If a recognizer is not present, this call to CoCreateInstance fails.
NO RECOGNIZER IS INSTALLED C# CODE
To determine whether at least one recognizer is installed, instantiate an InkRecognizerContext object as shown in the following C++ and C# code examples.

A recognizer provides specific information about its capabilities such as the language it can recognize and the manufacturer. You can query the recognizer's collection to determine which recognizer to use.

When recognizing asynchronously, the RecognizerContext object returns the RecognitionResult object in an event callback to the application. The RecognizerContext object enables you to recognize a given collection of strokes synchronously or asynchronously. RecognizerContext ObjectĪ RecognizerContext object is the instantiation of a given recognizer. You can then send a Strokes collection from an Ink object to a recognition engine and have it return a RecognitionResult object. You can use the recognition features of the Tablet PC platform API to query for information about the recognition engines that are available, such as what languages they recognize. Not all applications require the use of recognition, but because most applications were designed with text as their primary data type, the ability to convert ink into text is very valuable.
