例

この例では、マイクから翻訳認識エンジンを使用し、認識エンジンによって生成されたイベントを受信します。

public async Task TranslationContinuousRecognitionAsync()
{
    // Creates an instance of a speech translation config with your subscription key and region.
    // Replace with your own subscription key and service region (e.g., "westus").
    var config = SpeechTranslationConfig.FromSubscription("YourSubscriptionKey", "YourServiceRegion");

    // Sets source and target languages.
    string fromLanguage = "en-US";
    config.SpeechRecognitionLanguage = fromLanguage;
    config.AddTargetLanguage("de");

    // Sets voice name of synthesis output.
    const string GermanVoice = "Microsoft Server Speech Text to Speech Voice (de-DE, Hedda)";
    config.VoiceName = GermanVoice;
    // Creates a translation recognizer using microphone as audio input.
    using (var recognizer = new TranslationRecognizer(config))
    {
        // Subscribes to events.
        recognizer.Recognizing += (s, e) =>

        // Starts continuous recognition. 
        // Uses StopContinuousRecognitionAsync() to stop recognition.
        Console.WriteLine("Say something...");
        await recognizer.StartContinuousRecognitionAsync().ConfigureAwait(false);

        do
