Use Speech Controls and ASP.NET Application Speech Controls in Speech Control Editor to perform basic speech recognition tasks and to extend the ease and speed of development provided by Speech Controls to more complex dialogs.

Speech Controls

Use the following Speech Controls in Speech Control Editor to perform basic speech recognition tasks.

Speech Control Description

Speech QA

Use the Speech QA (QA) control to recognize responses and bind elements of the recognition results to Speech SemanticItem (SemanticItem) controls. QA controls are composed of:

  • Answers collections, which are composed of Answer objects that copy recognition results to the intended target SemanticItem controls.
  • ExtraAnswers collections, which are composed of Answer objects that copy extra recognition results to destinations other than the intended target SemanticItem controls.
  • Confirms collections, which are composed of Answer objects that confirm the recognition results in the intended target SemanticItem controls.

Speech SemanticMap

Use the Speech SemanticMap (SemanticMap) control to define semantic properties that a control sends to an application using Semantic Markup Language (SML). The SML contains the XML text that notifies the application of the user's answer. SemanticMap controls are composed of a set of SemanticItem controls that contain information about a control's semantic state and its binding and autopostback characteristics.

ASP.NET Application Speech Controls

Use the following ASP.NET Application Speech Controls in Speech Control Editor to extend the ease and speed of development provided by Speech Controls to more complex dialogs. Application Speech Controls contain linguistic components, such as built-in prompts and grammars, and provide other built-in mechanisms to handle speech events such as mumbling or silence that can occur during a dialog. Use these controls when recognizing common scenarios. Examples of these common scenarios include allowing users to pick a date, input an amount in dollars, provide a ZIP/postal code, or select an item from a list.
