How do I turn off auto-transcribe, for audio files in Notes.app notes?

I listen to my own foreign language-study MP3s on my phone, by importing them into Notes.app notes. I find that Apple tries to auto-transcribe the audio, as though it contained lyrics. Since the audio is a combination of Japanese and English, the results are a mess. - **Question**: I would like to turn off this auto-transcription function, but I don't see a way to do so. It is a waste of computer resources, and doubles the height of each affect MP3-object in the note. Any ideas?
