With the introduction of Windows Phone Cortana, the speech-activated personal assistant as well as the similar she-who-must-not-be-named from the Fruit companyspeech-enabled applications see more taken an increasingly important net in software development. A good way to see what this article will explain /service-to-man-is-service-to-god-essay.html online speech recognition net take a look at the screenshots of two different demo programs in Figure 1 and Figure 2.

The net asked the application to add one plus two, then two plus three. The application recognized these spoken commands and gave recognition net answers out loud. With speech off, the next spoken command to add one plus two online speech ignored. Figure 2 shows a dummy speech-enabled Windows Forms application.

I have online speech recognition used speech with Visual Studio andbut any recent version online speech recognition net work. After the template code loaded into the editor, in the Solution Explorer window I renamed file Program. Next, I added a Reference to file Microsoft. This DLL was not on my host machine and had to be downloaded. Installing the files necessary net add net recognition and synthesis to an application is not entirely trivial.

After adding the online speech recognition net to the speech DLL, at the top of the source code I deleted all using statements except for the one that points to the top-level System namespace.

Then, I added net statements to namespaces Microsoft. The first two namespaces are associated with the read article DLL. Somewhat confusingly, there are also System. The entire source code for the console application demo is shown in Figure 3and is also available in the code download that accompanies this online speech recognition net.

I removed all normal error checking to keep net main ideas as clear as possible. The class-scope SpeechSynthesizer object gives the application the ability net speak.

However, if speechOn is false, only the command to exit the program will recognition net recognized and online speech on; other commands will be recognized but ignored.

The Grammar object encapsulates the template and choices. In the online speech recognition net, I restrict the numbers to here to 1 through 4, and add them as strings to the Choices collection. A net approach is:.
