SpVoice SpeakStream method (SAPI 5.4)
Microsoft Speech API 5.4
The Speakstream method initiates speaking of a sound file by the voice.
SpVoice.SpeakStream( Stream As ISpeechBaseStream, [Flags As SpeechVoiceSpeakFlags = SVSFDefault] ) As Long
Specifies an ISpeechBaseStream object containing the stream.
[Optional] Specifies the Flags. Default value is SVSFDefault.
A Long variable containing the stream number. When a voice enqueues more than one stream by speaking asynchronously, the stream number is necessary to associate events with the appropriate stream.
The following code snippet demonstrates the use of the SpeakStream method. To run this code, create a form with the following control:
- A command button called Command1
Paste this code into the Declarations section of the form.
The Form_Load procedure creates a male and a female voice. The Command1_Click procedure causes the female voice to speak text into a file, and the male voice to play that file using the SpeakStream method.
