private void recognizerInfoButton_Click(object sender, EventArgs e)
{
RecognizerInfo info = _recognizer.RecognizerInfo;
string AudioFormats = "";
foreach (SpeechAudioFormatInfo fmt in info.SupportedAudioFormats)
{
AudioFormats += String.Format(" {0}\n",
fmt.EncodingFormat.ToString());
}
string AdditionalInfo = "";
foreach (string key in info.AdditionalInfo.Keys)
{
AdditionalInfo += String.Format(" {0}: {1}\n", key, info.AdditionalInfo[key]);
}
MessageBox.Show(String.Format(
"Name: {0 }\n" +
"Description: {1} \n" +
"SupportedAudioFormats:\n" +
"{2} " +
"Culture: {3} \n" +
"AdditionalInfo: \n" +
" {4}\n",
info.Name.ToString(),
info.Description.ToString(),
AudioFormats,
info.Culture.ToString(),
AdditionalInfo));
