Summary of SAPI usage in c how to use SpVoice

To use SAPI, first add a reference to DotNetSpeech, download DotNetSpeech.dll yourself.

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

When reading aloud, use

voice.Speak(string,SpeechVoiceSpeakFlags.SVSFlagsAsync);
Pause, use

voice.Pause();

Continue the reading from the pause, use

voice.Resume();

The stop function is not written clearly in most materials, and is rarely found on the Internet, used here

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

In this way, the function of "reading aloud", "pause", "continue" and "stop" can be realized completely.
