  "wonderful staff".

  Box 3: No

  Key phrase extraction does not have confidence levels.

  static async Task TranslateSpeechAsync() { var translationConfig = SpeechTranslationConfig.FromSubscription(SPEECH__SUBSCRIPTION__KEY, SPEECH__SERVICE__REGION);

  translationConfig.SpeechRecognitionLanguage = "it-IT";

  // Translate to languages. See, https://aka.ms/speech/sttt-languages

  translationConfig.AddTargetLanguage("fr");

  translationConfig.AddTargetLanguage("de");

  }

  Box 2: TranslationRecognizer

  After you've created a SpeechTranslationConfig, the next step is to initialize a TranslationRecognizer.

  Example code:

  static async Task TranslateSpeechAsync()

  {

  var translationConfig =

  SpeechTranslationConfig.FromSubscription(SPEECH__SUBSCRIPTION__KEY, SPEECH__SERVICE__REGION);

  var fromLanguage = "en-US";

  var toLanguages = new List { "it", "fr", "de" };

  translationConfig.SpeechRecognitionLanguage = fromLanguage;

  toLanguages.ForEach(translationConfig.AddTargetLanguage);

  using var recognizer = new TranslationRecognizer(translationConfig); }
