The Bing Speech Recognition Control
The Bing Speech Recognition Control enables a Windows 8, Windows 8.1, or Windows RT machine to convert audio speech input to written text. It does this by receiving audio data from a microphone, sending the audio data to a web service for analysis, and then returning its best interpretations of user speech as text.
When you embed the Bing Speech Recognition Control in an application, you control how your application interprets the text returned by the Speech Recognition Service. By linking to recognized patterns, such as e-mails addresses and URIs, you can link that text to common actions such as sending an e-mail or visiting a web site. You can also combine Speech Recognition with other services such as Bing Translator or Bing Search to translate spoken words or look up a recipe without using your hands.
If you want to create a custom speech recognition UI, you can use the APIs in the Bing.Speech namespace without putting a SpeechRecognizerUx control on the page. Instead, you can use the methods and events of the SpeechRecognizer class with your chosen UI elements. For more information, see How to: Add the Bing Speech Recognition Control to an application with a custom UI.
End users must have Windows 8 or 8.1 or Windows RT installed to use applications that include Bing Speech Recognition. Headset microphones are recommended.

To gain access to the Bing Speech Recognition Control and the web service that it depends on, you must subscribe at the The Windows Azure Data Marketplace, and then register your application. The subscription is free for the first 500,000 service calls per month.
When you are ready to publish your application, you can do so on the Marketplace. You can strong-name your application.
