Fill in the code snippet to correctly configure the translation languages and initialize the TranslationRecognizer.

static async Task TranslateSpeechAsync() {
  var config = SpeechTranslationConfig.FromSubscription("{{slot1}}", "{{slot2}}", "{{slot3}}");
  var lang = new List<string> { {{slot4}} };
  config.SpeechRecognitionLanguage = "{{slot5}}";
  lang.ForEach(config.AddTargetLanguage);

  using var audioConfig = AudioConfig.FromDefaultMicrophoneInput();
  using var recognizer = new TranslationRecognizer(config, audioConfig);

  var result = await recognizer.RecognizeOnceAsync();
  if (result.Reason == ResultReason.TranslatedSpeech)
    Console.WriteLine(result.Translations["{{slot6}}"]);
}
