PromptVolume Enumeration

Enumerates values for volume levels (loudness) in prompts.

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

public enum PromptVolume

Member nameDescription
NotSetIndicates that the volume level is not set.
SilentIndicates a muted volume level.
ExtraSoftIndicates an extra soft volume level.
SoftIndicates a soft volume level.
MediumIndicates a medium volume level.
LoudIndicates a loud volume level.
ExtraLoudIndicates an extra loud volume level.
DefaultIndicates the engine-specific default volume level.

Members of the PromptVolume enumeration are used by the PromptStyle(PromptVolume) constructor, by the AppendText(String, PromptVolume) method, and by the StartStyle(PromptStyle) method to specify the volume level for spoken text. The Volume property gets the volume for a PromptStyle object using a PromptVolume instance.

The Default setting for PromptVolume is full volume, which is the same as ExtraLoud. The other settings decrease the volume of speech output relative to full volume.

You can also set volume levels on the SpeechSynthesizer object. See TtsVolume and Volume.
