I know some users use SubtitleEdit; I’m not sure if that would work, assuming the info is in the SRT.
But there might be someone who knows more about SubtitleEdit and what it can do or how it can do it.
SubtitleEdit can even scan movies with no subtitles and analyze the audio, and what language the audio is in is what language the SRT will be in. It does audio/speech-to-text conversion.
