Good day! It is about Microsoft Server Speech SDK v11.0 (Server version).
I have run test example at MSDN sample . So English phrases -red,blue - recognized well. But I want to recognize Russian language too -install Microsoft Speech Recognition Language -TELE (ru-RU) and runs my app/
Code:
static void DoWork()
{
Thread.CurrentThread.CurrentCulture = new CultureInfo("ru-RU");
Thread.CurrentThread.CurrentUICulture = new CultureInfo("ru-RU");
// Create a new SpeechRecognitionEngine instance.
SpeechRecognitionEngine sre = new SpeechRecognitionEngine();
// Configure the input to the recognizer.
sre.SetInputToWaveFile(@"c:\Test\красный.wav");
// Create a simple grammar that recognizes "red", "green", or "blue".
Choices colors = new Choices();
// colors.Add(new string[] { "red", "green", "blue","красный" });
colors.Add(new string[] { "красный" }); //russian word- "red"
// Create a GrammarBuilder object and append the Choices object.
GrammarBuilder gb = new GrammarBuilder();
gb.Culture = new CultureInfo("ru-RU"); // add Culture Info
gb.Append(colors);
Console.WriteLine(gb.Culture.CultureTypes);
// Create the Grammar instance and load it into the speech recognition engine.
Grammar g = new Grammar(gb);
sre.LoadGrammar(g);
// Register a handler for the SpeechRecognized event.
sre.SpeechRecognized +=
new EventHandler<SpeechRecognizedEventArgs>(sre_SpeechRecognized);
// Start recognition.
sre.Recognize();
}
// Create a simple handler for the SpeechRecognized event.
static void sre_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
Console.WriteLine(String.Format("Speech recognized: {0}",e.Result.Text));
}
Error appears at this line:
sre.LoadGrammar(g);
The language for the grammar does not match the language of the speech recognizer.
So, how to fix this error? I try to set CultureInfo, but it does not works... Thank you!
Change the GrammarBuilder.Culture
property would solve this error.
After:
GrammarBuilder gb = new GrammarBuilder();
Add:
gb.Culture = Thread.CurrentThread.CurrentCulture
So that the grammar culture matches the recognizer.
