使用系统.用Kinect说话

本文关键字：说话 Kinect 系统 | 更新日期: 2023-09-27 18:16:46

我正在为一个大学项目开发一个原型语音到文本字幕应用程序。我将在我的项目后期使用手势识别，所以我认为使用Kinect作为麦克风源是一个好主意，而不是使用额外的麦克风。我的应用程序的想法是识别自发的演讲，如长句和复杂的句子(我知道这并不意味着语音听写不完美)。我看到很多Kinect的语音样本都提到了微软。演讲，但不是系统，演讲。因为我需要训练语音引擎并将一个DictationGrammar加载到微软的语音识别引擎中。演讲是我唯一的选择。

在使用Kinect作为直接麦克风音频源时，我已经设法使其工作，但由于我正在加载Kinect以进行视频预览和手势识别，我无法将其作为直接麦克风访问。

这是直接访问麦克风的代码，无需加载Kinect硬件来进行手势等，并且工作完美:

private void InitializeSpeech()
{
    var speechRecognitionEngine = new SpeechRecognitionEngine();
    speechRecognitionEngine.SetInputToDefaultAudioDevice();
    speechRecognitionEngine.LoadGrammar(new DictationGrammar());
    speechRecognitionEngine.RecognizeAsync(RecognizeMode.Multiple);
    speechRecognitionEngine.SpeechRecognized += (s, args) => MessageBox.Show(args.Result.Text);
}

这就是我需要在加载后通过Kinect访问访问源的地方，它根本没有做任何事情。这是我想要做的:

using (var audioSource = new KinectAudioSource())
{
    audioSource.FeatureMode = true;
    audioSource.AutomaticGainControl = false;
    audioSource.SystemMode = SystemMode.OptibeamArrayOnly;
    var recognizerInfo = GetKinectRecognizer();
    var speechRecognitionEngine = new SpeechRecognitionEngine(recognizerInfo.Id);
    speechRecognitionEngine.LoadGrammar(new DictationGrammar());
    speechRecognitionEngine.SpeechRecognized += (s, args) => MessageBox.Show(args.Result.Text);
    using (var s = audioSource.Start())
    {
        speechRecognitionEngine.SetInputToAudioStream(s, new SpeechAudioFormatInfo(EncodingFormat.Pcm, 16000, 16, 1, 32000, 2, null));
        speechRecognitionEngine.RecognizeAsync(RecognizeMode.Multiple);
    }
}

所以问题是，是否可能使用System。用语音代替微软。语音与当前的Kinect SDK，我做错了什么在第二个代码样本?

GetKinectRecognizer方法
private static RecognizerInfo GetKinectRecognizer()
{
    Func<RecognizerInfo, bool> matchingFunc = r =>
    {
        string value;
        r.AdditionalInfo.TryGetValue("Kinect", out value);
        return "True".Equals(value, StringComparison.InvariantCultureIgnoreCase) && "en-US".Equals(r.Culture.Name, StringComparison.InvariantCultureIgnoreCase);
    };
    return SpeechRecognitionEngine.InstalledRecognizers().Where(matchingFunc).FirstOrDefault();
}

使用系统.用Kinect说话

根据我自己的实验，我可以告诉您实际上可以同时使用这两个库。

尝试此代码而不是当前代码(确保添加了对System的引用)。演讲中,显然):

using (var audioSource = new KinectAudioSource())
{
    audioSource.FeatureMode = true;
    audioSource.AutomaticGainControl = false;
    audioSource.SystemMode = SystemMode.OptibeamArrayOnly;
    System.Speech.Recognition.RecognizerInfo ri = GetKinectRecognizer();
    var speechRecognitionEngine = new SpeechRecognitionEngine(ri.Id);
    speechRecognitionEngine.LoadGrammar(new DictationGrammar());
    speechRecognitionEngine.SpeechRecognized += (s, args) => MessageBox.Show(args.Result.Text);
    using (var s = audioSource.Start())
    {
        speechRecognitionEngine.SetInputToAudioStream(s, new SpeechAudioFormatInfo(EncodingFormat.Pcm, 16000, 16, 1, 32000, 2, null));
        speechRecognitionEngine.RecognizeAsync(RecognizeMode.Multiple);
    }
}

祝你好运! !

用System.Speech的引用试试这段代码。

using (var audioSource = new KinectAudioSource())
{
    audioSource.FeatureMode = true;
    audioSource.AutomaticGainControl = false;
    audioSource.SystemMode = SystemMode.OptibeamArrayOnly;
    System.Speech.Recognition.RecognizerInfo ri = GetKinectRecognizer();
    var speechRecognitionEngine = new SpeechRecognitionEngine(ri.Id);
    speechRecognitionEngine.LoadGrammar(new DictationGrammar());
    speechRecognitionEngine.SpeechRecognized += (s, args) => MessageBox.Show(args.Result.Text);
    using (var s = audioSource.Start())
    {
        speechRecognitionEngine.SetInputToAudioStream(s, new SpeechAudioFormatInfo(EncodingFormat.Pcm, 16000, 16, 1, 32000, 2, null));
        speechRecognitionEngine.RecognizeAsync(RecognizeMode.Multiple);
    }
}
