Specify the language
You can use the optional language_code parameter to specify the language of the spoken audio in the files that you submit to the API. If you don’t include a language_code parameter in your request, it defaults to en_us.
To learn more about using the language_code parameter, see Set language manually.
If you’re unsure of the language spoken in your audio file, you can use our Automatic Language Detection feature to identify the dominant language in your file.

You can use the optional speech_model parameter to specify the model. To learn more, see Select the speech model.
