ISpeechVoiceStatus Example (SAPI 5.4)

Microsoft Speech API 5.4

Interface: ISpeechVoiceStatus



The following code snippet demonstrates the use of all ISpeechVoiceStatus properties. To run this code, create a form with the following controls:

  • A command button called Command1
  • A list box called List1

Paste this code into the Declarations section of the form.

The Form_Load procedure creates a voice object. The Command1_Click procedure speaks two streams asynchronously, and adds status information into the list box every one-half second until both streams have been spoken.
