You are developing a speech translation service for recording lectures given in English (United Kingdom). The goal is to provide transcripts in multiple target languages: English, French, Spanish, and German.

Key requirements from the code snippet:

Source Language (Recognition Language):

config.SpeechRecognitionLanguage = "en-GB";

The input is English (UK).

Target Languages:You need to define a list of supported target languages. Since English, French, Spanish, and German are supported, the correct syntax is:

var lang = new List() { "en", "fr", "de", "es" };

This uses ISO language codes expected by the Translator API ("fr" = French, "de" = German, "es" = Spanish).

Recognizer Type:Since this is speech translation, you must use:

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

The TranslationRecognizer class is specifically for translating speech input into multiple languages.

Completed Codestatic async Task TranslateSpeechAsync()

{

var config = SpeechTranslationConfig.FromSubscription("69cad5cc-0ab3-4704-bdff-abf4aa07d85", "uksouth");

var lang = new List() { "en", "fr", "de", "es" };

config.SpeechRecognitionLanguage = "en-GB";

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)

{

foreach (var element in result.Translations)

{

AppendToTranscriptFile(element.Value, element.Key);

}

}

}

First Blank: {"en", "fr", "de", "es"}
