Cancels the asynchronous synthesis operation for a queued prompt.
Assembly: Microsoft.Speech (in Microsoft.Speech.dll)
You can also use this method to cancel an asynchronous speak operation for the following:
When you call SpeechSynthesizer.SpeakAsync(String), SpeechSynthesizer.SpeakAsync(PromptBuilder), or SpeakSsmlAsync(String), the method creates a Prompt object and populates it with the contents of the method's parameter, and returns the Prompt object. If you retain a copy of the returned Prompt, you can pass it into to cancel speaking content specified in a String or a PromptBuilder object.
