我在访问 kinect 的音频流以在我的项目中用于语音控制时遇到问题。到目前为止，我还没有收到音频流的响应。我正在使用安装了最新的 kinect sdk 包的 xna。
我正在使用的代码来自 sdk 中使用 xna 中的语音控制的示例，但在控制台应用程序中。
没有触发任何侦听器事件，我认为这是由于某些原因导致音频流未启动？
任何帮助，将不胜感激。
这段代码在InitializeKinect()我的程序部分：
// Obtain the KinectAudioSource to do audio capture
KinectAudioSource source = kinectSensor.AudioSource;
source.EchoCancellationMode = EchoCancellationMode.None; // No AEC for this sample
source.AutomaticGainControlEnabled = false; // Important to turn this off for speech recognition
source.Start();
RecognizerInfo ri = GetKinectRecognizer();
if (ri == null)
{
lol = "Could not find Kinect speech recognizer. Please refer to the sample requirements";
}
lol = "Using: {0}"+ ri.Name;
// NOTE: Need to wait 4 seconds for device to be ready right after initialization
using (var sre = new SpeechRecognitionEngine(ri.Id))
{
var colors = new Choices();
colors.Add("Kinect");
colors.Add("test center ");
colors.Add("left");
colors.Add("right");
colors.Add("indirect controls");
colors.Add("gesture control");
colors.Add("exit application");
var gb = new GrammarBuilder { Culture = ri.Culture };
// Specify the culture to match the recognizer in case we are running in a different culture.
gb.Append(colors);
// Create the actual Grammar instance, and then load it into the speech recognizer.
var g = new Grammar(gb);
sre.LoadGrammar(g);
sre.SpeechHypothesized += new EventHandler<SpeechHypothesizedEventArgs>(sre_SpeechHypothesized);
sre.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(sre_SpeechRecognized);
sre.SpeechRecognitionRejected += new EventHandler<SpeechRecognitionRejectedEventArgs>(sre_SpeechRecognitionRejected);
using (Stream s = source.Start())
{
sre.SetInputToAudioStream(
s, new SpeechAudioFormatInfo(EncodingFormat.Pcm, 16000, 16, 1, 32000, 2, null));
sre.RecognizeAsync(RecognizeMode.Multiple);
}
}
