Translation: Supported Languages

WLK supports translation into 201 languages from the FLORES-200 dataset through the NLLW translation system.

How to Specify Languages

You can specify languages in three different ways:

1. Language Name (case-insensitive): "English", "French", "Spanish"
2. ISO Language Code: "en", "fr", "es"
3. NLLB Code (FLORES-200): "eng_Latn", "fra_Latn", "spa_Latn"

Usage Examples

Command Line

# Using language name
whisperlivekit-server --target-language "French"

# Using ISO code
whisperlivekit-server --target-language fr

# Using NLLB code
whisperlivekit-server --target-language fra_Latn

Python API

from nllw.translation import get_language_info

# Get language information by name
lang_info = get_language_info("French")
print(lang_info)
# {'name': 'French', 'nllb': 'fra_Latn', 'language_code': 'fr'}

# Get language information by ISO code
lang_info = get_language_info("fr")

# Get language information by NLLB code
lang_info = get_language_info("fra_Latn")

# All three return the same result
