Have you developed a system for transmitting audio data supporting multiple language versions?

I have not developed a specialized system for transmitting audio data with support for multiple language versions, but I can describe a general approach to such a task.

To support multiple languages, the following are usually used:

• Storing audio files for each language separately, for example, in folder structures or with names containing the language code.
• Metadata indicating the language of the audio.
• When transmitting data to the client, the required language version of the audio is selected.

In Java, audio can be transmitted using streams, and for multilingual support, configuration or request parameters that determine the language can be used.

An example of a simplified selection of an audio file by language:

String language = "en"; // or "ru", "fr", etc.
String audioPath = "/audio/greeting_" + language + ".mp3";
InputStream audioStream = new FileInputStream(audioPath);
// then transmit audioStream to the client

Thus, the system flexibly supports different languages through the organization of storage and the logic of selecting audio.
