PromptEmphasis Enumeration

Enumerates values for levels of emphasis in prompts.

Namespace:  System.Speech.Synthesis
Assembly:  System.Speech (in System.Speech.dll)

public enum PromptEmphasis

Member nameDescription
ModerateIndicates a moderate level of emphasis.
NoneIndicates no emphasis.
NotSetIndicates that no emphasis value is specified.
ReducedIndicates a reduced level of emphasis.
StrongIndicates a strong level of emphasis.

Members of the PromptEmphasis enumeration are used by the PromptStyle constructor, by the AppendText method, and by the StartStyle method to specify the level of emphasis for spoken text. The Emphasis property gets the emphasis for a PromptStyle object using a PromptEmphasis instance.

NoteNote

The speech synthesis engines in Windows do not support variations in the emphasis of speech output at this time. Setting values for emphasis using a member of the PromptEmphasis enumeration will produce no audible change in the synthesized speech output.
