引用System.Speech.Recognition库-C＃

Question

I have a problem with my speech recognition reference in my C# application. When I reference it in my C# code with the using System.Speech.Recognition statement, the program will only run when a microphone is present and will refuse to run when the opposite case is true. Is there a way that I can use this library selectively, so that the program won't shut down if another computer that is hosting it doesn't have a microphone? Thanks in advance!

Answer 1

You need to check for the presence of the microphone before you create the SpeechRecognizer object.

Ie, instead of doing:

using System.Speech.Recognition;

SpeechRecognizer reco = new SpeechRecognizer();

do

using System.Speech.Recognition;

SpeechRecognizer reco = null;

if (MicrophonePresent())
{
    reco = new SpeechRecognizer();
    // do remainder of setup here
}
