Support specified language to decode

[alonsosilvaallende]

Thank you very much for your work. I want to use this package as speech-to-text to transcribe Spanish. When I change the language in both files to 'es', it seems to understand Spanish, however it transcribes in English. For example, I say "Cómo va la vida?" and it transcribes "How is life?" which is the correct translation of the phrase in English (so it understands what I say). Any idea how to change this? I am sure that I want to transcribe in Spanish so I don't need automatic dection of language or anything like that. Do you know how to tweak it so it does just that?
Thank you very much.
