Voice recognition without 3rd-party dll (C#)

I want to implement this solution.

But I don't want to use a commercial 3rd-party dll, e.g. Ozaki VoIP SDK.

Is it possible? Is there any open-source alternative?


  • ofcourse you can.
    by Adding the reference to your program in the solution Explorer if you are using Visual studio and then include the namepace System.speech.recognition;.

    using System.Speech.Recognition;
    using System.Speech.Synthesis;

    SpeechRecognitionEngine _recognising = new SpeechRecognitionEngine();
    SpeechRecognitionEngine listening = new SpeechRecognitionEngine();
    SpeechSynthesizer something = new SpeechSynthesizer();// allows the program to respond

    and look at the functions you get by calling the above instances and go from there , hope that helps . I know ,its old post but might be helpful to someone.
