static System::Collections::ObjectModel::ReadOnlyCollection<System::Speech::Recognition::RecognizerInfo ^> ^ InstalledRecognizers();public static System.Collections.ObjectModel.ReadOnlyCollection<System.Speech.Recognition.RecognizerInfo> InstalledRecognizers();static member InstalledRecognizers : unit -> System.Collections.ObjectModel.ReadOnlyCollection<System.Speech.Recognition.RecognizerInfo>Public Shared Function InstalledRecognizers () As ReadOnlyCollection(Of RecognizerInfo)Returns
A read-only collection of the RecognizerInfo objects that describe the installed recognizers.
Examples
The following example shows part of a console application that demonstrates basic speech recognition. The example uses the collection returned by the InstalledRecognizers method to find a speech recognizer that supports the English language.
using System;
using System.Speech.Recognition;
namespace SpeechRecognitionApp
{
class Program
{
static void Main(string[] args)
{
// Select a speech recognizer that supports English.
RecognizerInfo info = null;
foreach (RecognizerInfo ri in SpeechRecognitionEngine.InstalledRecognizers())
{
if (ri.Culture.TwoLetterISOLanguageName.Equals("en"))
{
info = ri;
break;
}
}
if (info == null) return;
// Create the selected recognizer.
using (SpeechRecognitionEngine recognizer =
new SpeechRecognitionEngine(info))
{
// Create and load a dictation grammar.
recognizer.LoadGrammar(new DictationGrammar());
// Add a handler for the speech recognized event.
recognizer.SpeechRecognized +=
new EventHandler<SpeechRecognizedEventArgs>(recognizer_SpeechRecognized);
// Configure input to the speech recognizer.
recognizer.SetInputToDefaultAudioDevice();
// Start asynchronous, continuous speech recognition.
recognizer.RecognizeAsync(RecognizeMode.Multiple);
// Keep the console window open.
while (true)
{
Console.ReadLine();
}
}
}
// Handle the SpeechRecognized event.
static void recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
Console.WriteLine("Recognized text: " + e.Result.Text);
}
}
}
Remarks
To get information about the current recognizer, use the RecognizerInfo property.
