描述

From what I can tell, auto-detection simply picks the language with the highest probability score. Sometimes, I know the language could only be 1 out of 5 possible languages. In such cases, it would be useful to be able to specify the possible languages, to improve the likelyhood of the auto-detection picking the correct language.

研究方向
First, examine the existing auto detection implementation in whisper.cpp, likely in whisper.cpp or common.cpp, to understand how languages are scored and the highest probability selected. Then, propose a modification to accept a user specified subset of languages (e.g., via an API parameter or environment variable) that filters the candidate languages before scoring. Consider adding a new function or modifying the existing whisper full default params to include a language filter. Test the change with a few languages to ensure detection accuracy improves.
