SAPI usage in c # -- SpVoice usage

To use SAPI, first add reference DotNetSpeech. Download DotNetSpeech. dll on your own.

Initialize the object, SpVoice voice = new DotNetSpeech. SpVoiceClass ();

When reading aloud, use

Voice. Speak (string, SpeechVoiceSpeakFlags. SVSFlagsAsync );
Pause and use

Voice. Pause ();

Continue reading from the pause. Use

Voice. Resume ();

The stop function is not clearly written in most documents and is rarely found on the Internet.

Voice. Speak (string. Empty, SpeechVoiceSpeakFlags. SVSFPurgeBeforeSpeak );

In this way, the functions of "read aloud", "pause", "continue", and "stop" can be fully realized.
