Hello @Erik Nguyen , Thanks for using Microsoft Q&A Platform.
Using language identification you can detect up to 10 possible input languages and automatically translate to your target languages.
auto_detect_source_language_config = \
speechsdk.languageconfig.AutoDetectSourceLanguageConfig(languages=["en-US", "de-DE", "zh-CN"])
For a complete code sample, please refer to language identification.
Is this something you are looking for?
