非英语语言的语音识别帮助

Question

I am trying to create a web app using asp.net to support Speech recognition. The catch is that I want to convert Swedish audio to text. I have tried several APIs and frameworks but no luck. I only could get AT&T to work, sort of. It only recognizes one word in a six word sentence. I also tried Micosoft.Speech library but couldn't get it to work. can anyone see what is wrong with my code?

var engine = null as SpeechRecognitionEngine;

engine = new SpeechRecognitionEngine(new CultureInfo("sv-SE"));


using (engine)
{
    engine.SetInputToWaveFile("C:\\temp\\samplecall.wav");


    var result = engine.Recognize();

    Console.WriteLine(((result != null) ? new SpeechRecognitionResult(result.Text, result.Alternates.Select(x => x.Text).ToArray()).toString : null));
    Console.ReadLine();
}

any other help regarding the speech recognition would be appreciated very much.

If you want to transcribe 8khz audio from calls, desktop speech recognition APIs will not help you, so Microsoft is not your choice.

AT&T should work if you configure it properly. Another alternative would be to build an callcenter acoustic model for CMUSphinx , the Swedish database for that is available.
